Do not allow bad air in the children's classrooms
The new ACU classroom purifier reduces the transmission of contagious diseases and helps those suffering from allergies and asthma to stay indoors without discomfort.

Bacteria and viruses have no wings but fly with the particles in the room. The ACU radically reduces the number of particles in the room and the really dangerous gases from mold (mVOC).


Using the ACU classroom cleaner, a large number of students and teachers who previously suffered from indoor air pollution can now stay in their classrooms without any problems.

The least dangerous particles are eliminated at an early stage of the cleaning process and at the same time healthy air is being creating.

The ACU air purifier also very efficiently removes odors and pollutants. Better air contributes to increased concentration levels and better study results.

The finer the particles in the air, the deeper they penetrate into the lungs and finally they reach the small balloon-like structures called alveoli.

The most dangerous particles are at nano size and come e.g. from modern diesel cars. These particles penetrate the lungs and enter the blood.

The ACU eliminates 100% of the static electricity that often occurs between students' clothes and chairs and benches. Static electricity causes particles in the air to be drawn to the students.

The air currents of the silent built-in fan have purifying effects in all corners of the room.

The ACU is a combination variant for quick and easy installation in ceilings, on walls, in corners or on tables.

The classroom purifier is maintenance free and produces no ozone.

It is easily connected with the supplied cord to a grounded wall outlet.

The ACU air purifier unit is available in three sizes for rooms of 84m2/200m3, 167m2/400m3 and  250m2/600m3 respectively.




Now you can see exactly how polluted the air is in your room or in the city air.

With more information, you can make better decisions - if for example an air cleaner should to be installed or if increased ventilation is needed.

You can connect multiple detectors and display the results of your property to a webpage or other display.

Everyone has probably experienced water drops from chilled beams.

Automatikprodukter, Sweden now launch a new condensation detector with early condensation warnings to solve a known moisture problem and prevent “indoor rain” from occurring.

Chilled ceilings are becoming more and more common in commercial buildings. By ordinary climatic conditions the operating temperature of the chilled ceiling may be close to the dew point with a potential danger of giving rise to water drops.

The new WCD condensation monitor WCD senses the danger of dew a short time before this occurs and reduces or shuts off the cooling water supply to the chilled ceiling.
The closer to the dew point the cooling water temperature can be, the better for the energy efficiency. The chilled beams can be made smaller.

The new condensation monitor WCD senses the danger of dew a short time before this occurs and reduces or shuts off the cooling water supply to the chilled ceiling.
The closer to the dew point the cooling water temperature can be, the better for the energy efficiency. The chilled beams can be made smaller.

New in the WCD condensation monitor is that it includes a humidity sensor and there is also a temperature sensor in order to calculate the dewpoint based on both variables RH and T.

When dew starts to build on this element the electrical resistance increases rapidly. The detector also emits an alarm at the onset of dew.

The condensation monitor has either a VFC (Volt Free Contact) or a current output and is mounted in a small housing that can be attached to the cooled surface to be measured.

The detector comes with a strap for easy mounting on the coolest position of the chilled ceiling.

It may also be screwed on to the chilled ceiling’s water supply unit.

The condensation monitor is a reasonable monitoring solution that can be used to prevent condensation damages to chilled ceilings from occurring.

This is a damper actuator series suitable for rough environments with a protection degree of IP66 in a durable housing.

The damper actuator allows farmers to make savings by avoiding exchanges of standard units at regular intervals.

Nuisance issues associated with air emissions in agriculture affect the ventilation systems.

Sources of dust in buildings are cattlefood, down feathers, microorganisms and crystalline urine.

Ammonia in poultry houses comes from waste.

Sprinkle supplies, waste disposal, humidity, pH and temperature affect the ammonia concentration and the level of emissions which together often cause standard engines to break down.

The product is fully protected against dust and against powerful water jets.

How can the number of false alarms caused by dirty Duct Smoke Detectors be reduced without any reduction in sensitivity?

This was an important starting-point when developing this completely new type of the smoke detector system described in this article.


As the smokes from the fire enters the ductwork system it may be diluted by with clean air from other areas, therefore, it is necessary for any detectors to be very sensitive.

Unfortunately, in the past, high sensitivity has often led to false alarms and as a result confidence in these systems has fallen.

The common reason for false alarms from duct smoke detectors is dust contamination and high airflow rates.

To manage these problems we often been forced to lower the sensitivity of the detectors either by:

  • Fitting a filter on the detectors to limit the effect of dust and high air velocity. Without a filter the wind velocity may be to high.

  • With a filter the sensitivity will be greatly reduced and when the filter is clogged with dust the detector may not function at all. Placing the detector outside the duct and diverting the air/smoke mix through tubes to the detector and back again.

  • What have we achieved here?
    If you take only a sample to the detector it may not be reprensentative of the main airflow but may solve the velocity problem.

    This leaves the dirt problem, so if the detector is not maintained a false alarm will still result.

    If you have difficulties detecting when the detector is in the ventilation duct, with access to all passing smoke, how difficult is it then to detect outside the duct where you only take a small part of the smoke and lead it out for detecting:

    • You must know surely that it is possible both to detect smoke and to make it at different levels.

    • You can’t mix the sensitivity of detection with different elements that cause false alarms.










    A Duct Smoke Detector called TDD (True Duct Smoke Detector) is able at a very early stage in the rough environment of a ventilation duct without giving false alarms.

    TDD is an optical obscuration designed to function inside the ventilation duct.
    The sensing part of the detector covers as much as possible of the duct.

    A infrared beam is transmitting through the sensing tube in the duct and if smoke present the beam is obscured to some extent and an alarm signal is given.

    The TDD-detector has an adjustable level of sensitivity that goes from 3 to 25% (0,1 to 0,9 db) obscurity for all different environments that can exist in a duct.

    You may ask, how does the TDD cope with dust?

    It surely must affect this detector as well.

    Dust is always present in the return air duct as is air velocity.

    The air will inevitably bring dust and this will stick to the detector optical parts, however, the detector electronics constantly monitor the obscuration within the sensing tube.

    The air brings along dust and particles that of course also catches of the TDD-detector.

    Despite it manage to be dirty without making a false alarm and without loosing its sensitivity and as the level changes slowly over a long period of time (Weeks or Months).

    The signal is adjusted to compensate for this build up of dust, however, should the obscuration change quite rapidly (Seconds) this is signalled as smoke and will cause an alarm after an initial delay to compensate for drops of water or dust that disturbed from duct wall etc.







    Self compensating
    Eventually even the TDD will become dirty, how long time this takes is a function of the environment in which the detector is used.

    The internal calibration of the detector is provided at an outgoing terminal in order that the level may be seen if connected, for example , to a BMS system.

    This signal is 2 to10 volt with 3 volt being clean 10 volt dirty or in alarm and 7 volt being service indication.

    Modern smoke detectors are often difficult to clean, some needing special knowledge due to the radioactive nature of the devices used with consequential costs involved in special instrumentation required to recalibrate them after cleaning.

    Normal maintenance staff without previous training can clean TDD.

    If they clean a pair of glasses they can clean the TDD it is the same technique.

    This provides a better economic solution for the low life cost (LCC) for the end users.

    Adjustment of TDD to different supervision system
    TDD is constructed to be connected to all in the market existing Fire Alarm- and BMS- system, both digital and analogue.

    As standard there is two alarm output with an open switch for smoke alarm and one analogue 2-10Volt for an output service alarm.

    The output service alarm can for example be connected to system that are computerized and where you can see the dirtiness 0-100% on a BMS or Webb.

    The option variant of the detector has 2 output relays for smoke alarm.

    One example for how to use the two alarm output can be that alarm output 2 is used for control of fire dampers and valves and gives a local alarm signal while output 1 is used for external alarm signals, suitably for fire defence.

    Reset the alarm signal
    The detector can be reset by pressing the reset button (front panel) for one second or by interrupting the supply voltage (Remote reset).

    The detector can also be reset automatically when the around obscurity ended.

    Ozone free air purification with the new SPG ionization needle

    Many applications require odor control. Odors can indeed be difficult to trace.

    Odors can be hard to track down and many times, exhaustive (and expensive) IAQ investigations raise more questions than they provide answers.

    Many applications require odor control. SPG patented needlepoint technology has been used in:

    • Airports

    • Hospitals

    • Casinos

    • Locker rooms

    • Restaurants

    • Dining halls

    • Morgues

    • Nail saloons

    • Kennels

    • Veterinarian offices

    • Fish markets

    • Fire damage areas

    • Trash rooms

    In general, SPG’ technology can effectively control gases with electron volt potentials less than 12.
    Every gas has an electron volt potential (Ev) associated with it.
    SPG purposely controls the ionization output so nothing over an electron volt potential of 12 will be oxidized; this is how SPG prevents ozone from being created. Oxygen’s Ev number is a little over 12.

    If you ionize oxygen, ozone is created, and that is an undesirable byproduct.

    Below are odors effectively controlled by SPG’ technology:

    • Food Odors

    • Diesel Odors

    • Jet Fumes

    • Cooking Odors

    • Body Odor

    • Mold & Mildew Odors

    • Red Tide Odor

    • Dirty Sock Syndrome

    • Helicopter Odors

    • Cigarette and Cigar Smoke Odors

    A recent study from an installation at Methodist Hospital in Houston, Texas, shows how well the SPG-IBAR system controlled the problem-atic diesel generator exhaust odors during weekly testing.

    When the backup generators are tested, the exhaust odors were being drawn back into the building causing a high volume of complaints..

    After the installation of the SPG-IBAR system, the odor complaints ceased.

    The SPG ionization needle does not need to be replaced which eliminates annual costs, is ozone free and fits ionization units from other manufacturers.

    Automatikprodukter markets a new portable instrument that measures the ambient levels of ozone concentrations with great accuracy.

    Thus, people who in the years to come will be exposed to ozone can be protected against this deadly toxic gas which is triggered by rising ozone levels.

    The human olfactory sense is not sufficiently sensitive to detect the metallic smell of ozone when the gas has reached hazardous levels.

    The sensitivity of the human olfactory dense varies and is influenced by local conditions.

    Ozone is used in many industrial processes and commercial buildings.

    It has therefore become increasingly important to measure ambient ozone around ozone generators, ozone equipment for rooms, air purifying units, electrostatic filters, needle- and tube ionization units, garbage room units, sets with UV radiation and other types of air conditioning systems that induce ozone.

    A unique sensor technology provides high accuracy and precision measurements with detection limits down to 1 ppb.

    This gas-sensitive sensor has a dynamic setpoint for reducing drift.

    Easily serviced measuring instrument makes downtime shorter and one of the unique characteristics of the portable ozone detector is the ability to change the sensor heads between devices.

    Sensors can be easily replaced without additional configuration.

    The choice of three portable ozone measuring instrument provides custom usability depending on the application:

    • PS 500 is the complete package that includes built-in data logging functionality, alarm setting levels and control options.

    • If ozone control is the most important requirement the PS 300 may be the right option.
      It is equipped with high and low alarms and user defined setpoints for the monitoring and control of ozone concentrations.

    • PS 200 is the basic model. It is mainly suited for health and safety samples and to test against personal exposure.

    Reduced maintenance costs for gas detectors

    For air quality monitoring in car parks and garages, Automatikprodukter introduces an innovative replaceable sensor.  

    The sensor can be replaced without specialist competance.

    Whether in underground parkings areas, tunnels or loading zones – even the smallest gas leakage must immediately be detected, located and reported.

    The sensors specially optimized for the different gas types, CO, NO2 and LPG work selectively in the defined hazard area.

    The gas sensors in conjunction with sophisticated controllers and obligatory warning devices primarily monitor the air quality required for health and also reliably supervise the plant.





    Revolutionary replaceable sensors provide cost savings and independence.

    Gas detection systems must not only meet the latest technological standards, (Level SIL2 EN50271), but also the latest legal requirements EN50545.

    From time to time, but at least every 2 years, these gas sensors have to be adjusted or recalibrated in order to ensure proper monitoring.

    The necessary calibration of the sensors has been a very complicated procedure so far: the underground garage operator was dependent on an external certified specialist who had to come regularly for the on-site calibration of the sensors, costing a lot of time and money.


    Thanks to the replaceable sensor, recalibration becomes a home game.

    Automatikprodukter sends the car park operator the newly calibrated sensor heads on request, which can be replaced independently according to the principle Plug & Play with little effort and in a short time.

    This means significant time and cost savings, because without the need to employ an external specialist you can carry out the replacement much faster and cheaper.

    This ensures a low life cycle cost (LCC).


    LCC means the total investment and operating costs during the product's life time.

    Sick building syndrome: delivering the complete picture with instant clarity

    As the move to more tightly-structured indoor air quality (IAQ) legislation continues, environmental consultants, safety professionals and building managers all search for more accurate, reliable and flexible systems to monitor potentially harmful indoor environments.

    First identified as ‘office illness’ back in the 1970s, as data emerged linking office workers in newly constructed buildings and tenants in new homes with a range of non-specific symptoms, sick building syndrome (SBS) as it became known was identified in around 20% of newly constructed commercial buildings in Europe.

    Research soon linked SBS and its impacts on humans - such as headaches, eye irritation, respiratory discomfort, dizziness, visual disorders and memory impairment - to a number of specific indoor sources, many of which contain volatile organic compounds (VOCs). These sources include carpets and furniture, cleaning products, office equipment, human occupancy as well as microbial action and pesticides.

    These specific sources release VOCs into the atmosphere, known as outgassing.

    The effects of outgassing are often intensified by poor heating and ventilation (HVAC) systems or the over-use of air recirculation in both residential and commercial buildings, exacerbating symptoms.

    Now, with the emergence of potentially much more stringent IAQ legislation, those with environmental, safety, hygiene and building control responsibilities are beginning to recognise the complexities of monitoring IAQ, particularly in larger buildings.

    This is because there is now a growing understanding that the impacts of SBS are not necessarily uniform across a building, and may vary significantly over a single floor.

    And this variation may well be caused by human occupation, or other variables throughout the course of any given period.

    The monitoring complexities caused by lack of uniformity in IAQ can be further exacerbated by the potential for additional reading errors caused by humidity or contamination. These errors can range between 15-20% and can, in combination with lack of detailed zone-by-zone data, render the entire monitoring process void.

    Automatikprodukter can deliver air quality detectors to provide highly accurate and continuous data information about indoor air in different zones.

    QHT and BIO

    The IAQ detector makes the picture complete by offering continuous and highly accurate humidity, temperature and barometric pressure information so that variables, such as human proximity can by tracked, day and night.

    The detectors provide continuous, highly accurate IAQ monitoring and can be tracked throughout the building zone-by-zone, floor-by-floor no matter how large the facility may be.

    This means users, whether experienced environmental consultants, safety and hygiene professionals or building managers, will have a complete picture of ever-changing environmental conditions with instant clarity.

    Traffic lights warn students of poor indoor air

    A standard wall mounted CO2 detector has been equipped with LED indicators to alert students and teachers of excessive levels of CO2 in their classroom.

    The new RC 24 CO2 detector from Automatikprodukter features LEDs of different colors indicating different CO2 concentrations.

    Red means bad air (1100-2000ppm), yellow means that the air is ok (900-1000ppm) and green indicates fresh air
    Red light means that ventilation should be increased by for instance opening windows.

    It takes about two minutes to reduce the CO2 concentration from 1400ppm to 800ppm.

    The RC24 detector indicates the CO2 concentration in an easily understood way.

    It is better to trust CO2 detectors than ventilation systems which according to media often do not function properly.

    The RC 24 CO2 detector continuously monitors the air; the LED’s on the detector are visible for both students and teachers.

    Poor air affects a student'' ability to concentrate. It makes both students and teachers tired, which affects learning in a negative way.

    Teachers working in schools with fresh air have fewer sick days than their colleagues in 'sick' schools.

    The RC 24 CO2 detector also features a selectable analog output 4-20mA, 0-10Vdc or 0-5Vdc and Modbus communication that can be connected to an automatic monitoring- and control system of the CO2 concentration.

    The detector is optionally available with a built-in monitoring device for humidity and temperature - RCHT 24.

    New detector secures visual control of air quality.

    The last few years of international debates on clean air has attracted much attention and created an increased focus on good air in schools, etc.

    AP launches new affordable air quality detector that can provide up to date information visually via a display and prevent bad air.

    The display automatically shows for the people in the occupied zone four different levels of current status:

    • Bad

    • Poor

    • Fair

    • Fine

    Easily understood by everyone!

    The QHT 24R detector also includes features for humidity and temperature with selectable output signals 0-10Vdc,
    0-5Vdc or 4-20mA.

    Modbus RTU is built-in as standard.

    The QHRT 24R is marketed at a time when there is an increased focus on clean air. Safgety awareness regarding air has also become an issue of great importance.

    It has been established that welding plants, swimming pools, laboratories, gymnasiums and many other unhealthy areas need better ventilation to achieve a better indoor climate. AP Environmental Detector BIO can be the solution for a better indoor environment.

    Most systems designers use CO2 sensors to indicate personal load as part of demand-controlled ventilation.

    A disadvantage of this method is that it ignores the harmful impurities that may be present in the air even when CO2 levels are low.

    VOC sensors offer the best of both worlds.

    They allow ventilation based on occupancy and air pollution - and does not require any more work than installing a CO2 sensor.

    The Environmental BIO detector measures both the VOC and the CO2, and does this by measuring volatile organic compounds (VOCs) and leaves the output signal corresponding to a CO2 level of 0-2000 ppm.

    This means that systems designers can use VOC/CO2-based detectors and simultaneously monitor both personal load and VOC.

    One of the keys to the AP sensor´s reliability is that VOC is an indicator of human load just as good as CO2.

    This is because a large proportion of volatile organic compounds in indoor space is generated by human breath, sweat and skin or from colognes and perfumes etc.

    Extensive research has been conducted on human occupancy, VOC levels and CO2levels in 1,500 offices, schools and homes to establish the relationship between these three factors.

    The research identified a complex correlation algorithm between VOC and CO2. This algorithm was used to create the output of the VOC sensor.

    The accuracy of this output compared to CO2levels is shown in the pdf file Experience tests.

    The graph shows that the VOC sensor tracks occupancy and that production has a high correlation with CO2level.

    The detector indicates when the additional VOC or air pollution occurs from cooking or other activities.

    Gas Central for reduced air pollution

    The Gas Central, VOC, from Automatikprodukter comes with an integrated detector that senses the need to remove odors to improve the air quality and optimize ventilation.

    The integrated CO2 / VOC sensor (VOC = Volatile Organic Compounds) measures the concentration of various gases and odors such as tobacco smoke, body odors, frying, carbon monoxide, methane, ethanol, acetone, methanol, etc. in the room.

    This gas central intended for indoor use, offers a solution in a variety of applications in for example restaurants, pubs, kitchens, toilets, recreation areas, locker rooms, smoking rooms and controlled ventilation in homes.

    The gas central can be supplemented with an additional external detector for detection of other gases.

    The gas central significantly adds to the comfort in office buildings while at the same time reducing energy consumption.

    The sensor is pre-calibrated and easy to install. As a result of this, commissioning can be made with the regular installation measures including placement on the wall 1.6 m above the floor. There is no need for additional calibration by a qualified technician.

    By using the detector, energy costs like heating and running costs can be reduced by better optimization of the ventilation system.

    AP launches a new indoor monitor measuring PM 2.5 particles (less than 2.5 microns). The monitor instantly provides clear information on air quality.

    This means that everybody who is concerned about their indoor environment can now have full control over the air quality.

    People in schools, or in their homes, etc., can clearly see how clean the air is in each room. The PM2.5 concentration is shown as averages over an hour in six levels and gives clear indication about just how clean the air is.

    The information is clearly presented on the front of the monitor/detector and one can easily determine if proper filtration comes from the ventilation system or from another installed air purification technology.

    An LCD display shows real-time measurement of PM2.5, with moving averages, and actual measurement of temperature and humidity.

    The integrated sensor has an optical sensing method using infrared LEDs, monororing in real-time indoorPM2.5 concentrations.

    The technique has a compensation method with up to 10 calibration points to ensure PM2.5 accuracy in different environments.

    Public demands for clean air means that there is a strong preference for an indoor monitor showing local air quality in the rooms as well as being able to connect this information to a parent monitoring system.

    Now this indoor monitor is available either as a table-top or for wall mounting.

    Having installed the indoor monitor, each one of us can take control of the air quality produced by the ventilation system. This provides  an entirely different insight into what happens to the air in different rooms at different activities in a way that has hitherto not been possible.

    The wall mounted option is equipped with Modbus connectivity.

    The product comes with guide which is easy to understand. This guide should be placed adjacent to the product.

    The indoor monitor should create attention and impetus to improve the air quality.

    Discover the risk of "indoor rain" from chilled ceilings / beams.

    The WCD 2 is a new condensation monitor, which monitors and detects the risk of condensation.

    Early condensation warnings is one way of solving this moisture problem and prevent possible presence of "indoor rain".

    With a microprocessor based moisture and temperature system the dew point is calculated in real time.



    When the dew point is getting close the WCD 2 monitor rapidly emits a flashing light and the relay output switches to turn off or reduce the cooling water supply to the chilled ceiling / beam when:

  • the dew point is reached

    Daylight control provides significant energy savings by switching lights on or off or by providing analog control according to the amount of daylight required for a certain activity adjacent to the light source.

    A light detector detects how much light there is in the room and adjusts the light source accordingly.

    The light level is lowered or raised automatically or is on / off controlled.

    Daylight control connected to fluorescent lights gives automatic adjustment of light level.

    The detector indicates when the light level should be increased or decreased.

    This technology is also available for outdoor lighting and greenhouse applications.

    Lighting control can generate energy savings of up to 70%.


    The detector is equipped with a switch for optional setting in different lux ranges with output 0-10V/4-20mA for easy adaptation to the controller / PLC or other control system.

    AP light detector provides efficient indoor and outdoor energy depending on the current light conditions.

    Gas detection for parking houses

    For the best gas detection in closed parking houses, we recommend the following:

    The NO2 010 detector for diesel cars should be placed 2 dm above the floor since the gas settles like smoke above the floor. NO2 is a heavy slow-moving gas.

    See pdf about number of detectors and location.

    Evacuation of exhaust air is achieved by means of depression with the right balance of supply and exhaust air.


    The detector is programmed 2 ppm for warning alarms and 5 ppm for sharp alarms.

    Extraction fans are used to evacuate the exhaust fumes at high speed to disperse air instead of influencing the surrounding area.

    Inlets to the extractor fans are placed close to the floor to collect the exhaust fumes.

    At high gas levels the system alerts a flashing light or warning siren while starting / speed regulating the current extraction fan automatically so that the gas concentration is reduced.

    Nitrogen dioxide is a carcinogen and can not be filtered out by your nose or throat but enters the lungs and then into the bloodstream and eventually ends up in your heart.

    Energy Savings


    Pioneering wireless sensor technology SonNet from Automatikprodukter has made it possible to save 15% of the electrical installation costs for building automation contracts.
    Electrical installation costs are often as high as 30-40% of the building automation contract.

    SonNet is based on a completely new installation philosophy of building automation with radio-based sensors for new and existing building automation controls.
    Electrical installation costs have been the most expensive part of all projects in building automation.

    With wireless sensors offers an effective concept that reduces expensive labor costs, while making a better long term solution for property owners.

    It is only recently that wireless sensors have become economically viable for widespread use in applications for building automation.
    Previously, wireless sensors have only been installed in places such as museums, churches and other historic buildings where exposed wiring is not allowed.
    With the same or lower installation costs, wireless systems can replace wired systems in a variety of different buildings.

    Since wireless sensors can be easily repositioned, their use can be very advantageous when system changes are made.

    A property owner may, for example determine that an accurate temperature measurement is necessary in areas with certain critical areas, which means that additional sensors need to be installed.
    If the ceiling is already in place and the wall surfaces are finished, the installation of wired sensors may prove costly and cause significant chaos.

    This problem does not occur with wireless devices.

    Sensors may also need to be moved when all the equipment is finally installed in a new building.
    Rearrangement of furniture often occurs and it is not uncommon that sensors end up very close to copying machines, vending machines, which certainly does not contribute to accurate control.

    Wireless sensors overcome these limitations since they can easily be repositioned.
    The same advantages occur when new or additional equipment is to be installed since wireless sensors will substantially reduce both the number of business disruptions and costs.

    Clean Air company AP have developed a new technology for indoor air hygiene. A device installed in a suspended ceiling system called UC, removes impurities and odours with increased efficiency while providing a significant improvement of wellbeing.

    As a consequence, 60% of the population staying indoors can now breathe clean air, even if the outside air is polluted. This has previously been difficult to achieve in the indoor environment.

    Indoor air is recirculated and purified in modules, available in versions for air flows up to 1450m3/h The system stops the transmission of contagious diseases (colds, flu, etc.) and kills the microorganisms present in the air such as bacteria and mold.

    An oxygen generator is available as an option to control CO2 levels and other gases.

    This device is suitable to use in order to reduce the CO2 level in meeting- and conference rooms, where the normal ventilation is insufficient.

    There has been a strong demand from our customers for a combined room based air purification system that effectively and quickly filters out micro particles, dust, smoke, etc. down to 0.1 micro and significantly reduces odour while controlling the CO2 level in the rooms.

    90% of the impurities can be reduced within the first 10 minutes. The bacterial levels are reduced by up to 88%.

    The optimum air hygiene technology has been developed in combination with scientific measurements of air quality before and after UC installations.

    The UC technique is based on a an electrostatic filter in combination with generation of negative ions. By restoring the natural balance between positive and negative ions real oases are created in rooms resulting in increased concentration and productivity among employees.

    The UC is a modular technology for easy and quick installation in suspended ceilings 600x600mm and is available with up to 24 installation options.

    The UC has a negligible noise level and has a very low power consumption.

    It is run by remote control, which has a built-in control box giving operational status.

    In short, UC is the perfect choice for optimum air hygiene in rooms.




    NAI Air Purification Filter
    AP is launching an air purification filter called NAI, which keeps air ducts constantly clean.

    It is mounted after the electrostatic EFX filter.
    The combination provides purification up to 99% and eliminates particles down to 0.1 microns.
    This type of cleanup and near sterilization has been developed after several studies, which demonstrated that bacteria / mold in conventional ventilation ducts are often the cause of certain diseases.
    Inadequate cleaning allows the spread of mold in the ventilation ducts, which are ideal sites for growth of colonies of bacteria and viruses.

    Heavily soiled ducts should be cleaned first and the technique is preventative.
    The new purification principle “negative ion generation" neutralizes the air during continuous operation for an unlimited period.
    The negative ion generation cleans the inner walls and makes them almost become sterile.
    Furthermore, certain odors and gases are minimized in this phase.
    A favourable climate is created in the occupational zone when the polluted air is gone and the air has been purified by means of negative ions.
    Negative ions remove pollen, dust and mold.
    For the property owner this means that periodic chemical or mechanical cleaning operation costs previously done with the help of a robot can now be reduced.

    The EFX / NAI method saves money for the customer.

    Detector that alerts for ozone toxicity

    A new series of detectors from AP measure ambient ozone levels in industrial kitchens, water and sewage plants, homes and industries in a variety of security related applications.

    Ozone is now used in many industrial processes and commercial buildings. It has become increasingly important to measure ozone content around different types of devices that produce ozone indoors such as air purification devices, bipolar ionization plants, devices with UV radiation, etc.

    The ozone detector is designed to protect and alert against ozone exposure. It meets the Work Environment Authority's requirements for level limit 0.1 ppm (exposure limit period), and 0.3 ppm max limit (exposure limit over a period of 15 minutes). It detects leaks and provides automatic control of processes and equipment.


    In the U.S. the hygienic exposure limit is 0.05 ppm (50ppb), an alarm level we strongly recommend.

    O3-detectors from AP are designed for early detection of ozone, measurement and control of the air, including process ozone (high concentrations), ambient ozone (low concentrations) and fluid gas ozone (low concentrations).

    The detector is pre-calibrated and easy to install.

    The start-up process is done according to standard installation practices, including position on the wall 0.3 m above the floor.

    Additional calibration by a qualified technician is not needed.

    Ozone is a toxic gas and more and more Europeans will die of diseases induced by rising levels of ozone in the coming years.

    Approximately 1400 people die annually in Sweden of ozone.

    The human olfactory organs cannot detect the metallic smell of ozone. Furthermore the sense of smell varies from person to person and is also affected by local environmental conditions.



    Water damage is often unexpected. Early detection is vital to limit the extent of the damage.

     The damaged area can be divided into two groups:

    • Unforeseen water damage

    • Intentional water damage

    The most common causes of water damage are a technical errors, improper construction, poor maintenance and supervision, lack of waterproofing, carelessness, accidents and water damage caused by workmen.

    Reasons for intentional water damage, are for example, deliberately turned on water taps where the drain is blocked and vandalism causing broken water pipes.

    Projecting guides

    • Complement existing controls /alarm-installations in buildings with water detectors

    • Freezers and refrigeration systems should be equipped with alarms

    The importance of early detection is of vital importance to limit the damage.

    AP launches an electrostatic filter cartridge called EFX, which is environmentally friendly, energy saving and providing clean air at the same time. 

    Property owners do not have to now change filters several times per year and can avoid complaints about ventilation, since the air has been washed clean. The cost has been reduced for operation and maintenance while at the same time you save energy. 

    The EFX has been designed to be used in schools, hospitals, apartment buildings and industrial processes, etc. and for companies working with energy-saving measures, EPC, Energy Performance Contracting, etc., where you want to create good indoor air quality.


    Electricity consumption for the operation of fans in ventilation systems in different buildings is an essential part of the overall electricity consumption in these buildings. 

    A great part of the electricity needed for the operation of fans - sometimes up to 30% - is caused by the pressure drop in the filters of the air supply units. 

    The EFX is a filter with a low pressure drop and does not change significantly during the operating time and thus requires less work for the fan motor.

    The filter is reused and only needs washing. You avoids the problem of service staff working in unhealthy environments when changing the pocket filters.

    EFX is designed to last for 20 years, with nothing more than maintenance and cleaning.
    As a consequence of this Life Cycle Cost is low.


    The electrostatic filter is based on a technology with efficient particle capture and acts as an air purifier for rooms. A capture system holds the particles in position. 

    The filter has been developed in collaboration with the Institute for Hygiene and hospitals.
    Hospital staff have conducted product tests. 

    Common air purification, energy savings and no changes of filters are much appreciated improvements.

     “I have dreamed of this kind of filter for years. So far, you have had to stand in the dust with a protective mask to replace the pocket filter. This has obviously been a poor and unhealthy working environment. With this filter, you save working hours, and in fact I think all pollutants have now disappeared in the occupied zones.

    Not having to discard a number of pocket filters, as refuse, I believe this is also the way towards a more sustainable society “ says Harry Kraaijenhagen from Airionic in Mölndal (Gothenburg suburb).

    EFX is available in a number of air modules assembled from smaller to larger systems in relation to airflow in the ventilation system. It fits in both existing and new air supply units and can replace the old filter without significant adjustment costs. 

    One conclusion is that it pays to install electrostatic filters. This has been found out life cycle cost calculations.
    The electricity consumption for fan operation required by the air filter, becomes more than 30 % lower, if one chooses to install EFX electrostatic filters.

     AP contribute to accelerating the development of more efficient ventilation products and - systems for energy efficient “Green Buildings”.

    The EFX is a climate-smart filter kind to the earth's resources.

    Detector for hydrogen sulphide protects people and plants from toxic emissions.

    The new gas detector H2S from AP is designed to protect people, equipment and plants from risks associated with hydrogen sulphide (H2S). It is equipped with a Modbus communications protocol to facilitate bus communication.

    Hydrogen sulphide is a toxic gas whose odor is usually described as that of "rotten eggs".

    At high concentrations, however, there occurs a paralysis of the sense of smell.

    It is therefore not possible to use the sense of smell to determine if an area is dangerous due to the presence of hydrogen sulphide.

    Modbus is a proven communications protocol for the instrumentation that provides digital communication without disturbing the integrity of the analog output signal 0-10Vdc or 4-20mA.

    Modbus allows multiple variables, parameters, device configuration and diagnostics to be transferred digitally simultaneously with the analog signal.

    The H2S gas detector is also available in explosion-proof design and ATEX-compliant with CE certification.

    The gas concentration is displayed on an LED display.

    The gas detectors come as standard with two analog outputs, and as an option with two additional relay outputs.

    H2S is equipped with an electro-chemical element, which are highly selective and unaffected by ammonia, alcohols and other gases that are commonly found in these environments.

    The detector monitors H2S gas in parts per million (ppm) and provides status indication. It is also equipped with alarm outputs.

    The sensor is available in 0-50ppm 0-100ppm or 0-200ppm to support a wide range of applications.

    For the smoke control systems to function satisfactorily, one must first of all have a smoke detector that is manufactured for ventilation ducts.

    It must be designed to withstand the environment in the ventilation duct without interference.

    There are two major interference problems which have caused a huge number of false alarms on duct smoke detectors.
    Pollution is a great problem in all ventilation ducts.
    The detectors detect pollution as smoke, and often emit false alarms.

    The second major problem is the air velocity in the duct.
    High air velocities often interfere with detectors.





    The FCO detects the fire before the smoke has emerged

    The FCO is a high sensitivity detector which detects the first stage of a fire - namely the gasification which preceeds the development of smoke.

    The FCO measures the concentration of CO in the ambient air and mixes completely with the oxygen. This ensures a comprehensive detection of the room or space.

    The FCO works with relay outputs, analog signals and bus systems e.g. Modbus and can thus be connected to all smoke control systems, DDC-controllers and fire alarm systems.

    • The sensitivity can be selected from 5 - 45 ppm with an accuracy of + /- 3 ppm

    • 2 relay outputs for alarm 10 ppm (for control measures), respectively 25 ppm (for real fire alarm)

    • Can be placed virtually anywhere, need not be placed in a turbulent flow

    • Works even when stratification prevents the smoke from spreading

    • CO penetrates dirt and dust etc.

    • Creates no false alarms

    • In a ventilation duct the IP65 protected detector can be accessed via a manhole

    • Detects up to a height of 12 meters

    Installation inside ventilation duct


    The OVK detector has a cleansing alarm for early action against pollution from dust and other particles that circulate in the ventilation systems of properties.

    To prevent deterioration of the circulation and efficiency alarm at various levels are given for monitoring measures or for cleaning of ventilation ducts.

    The OVK detector improves your indoor climate and prevents the spread of fire by means of an automatic cleansing alarm.




    The TDD duct smoke detector detects smoke at all hours directly inside the duct

    Countless examples show that a small fire damage can have huge smoke and clean-up damages. This is mainly due to the new plastic material now available on the market.

    Detecting smoke automatically in a duct should not be especially difficult if you had tried to make a detector specially adapted for ventilation ducts and the problems that can occur there.

    What has been done before are adaptations of ordinary standard room detectors for installation in ducts.

    The TDD is a duct smoke detector designed for ventilation that

    • works inside the ventilation duct

    • has adjustable sensitivity levels for various environments that may exist in a duct

    • enables smoke detection to be measured several times per second and dirt to be measured every two hours

    • tells you during the whole operating time how clean/dirty it is

    • compensates automatically for the current pollution level with no change of sensitivity

    • provides a special service alarm when it reaches maximum contamination

    • has marker that clearly indicates which detector has given the alarm

    The TDD is total economic LLC and this can be summarized as follows:

    • Low operating costs for the owner, long time between cleaning sessions, you know exactly how dirty the detector is

    • No false alarms - no emergency expenses

    • No lost confidence in the alarm systems

    The TDD is therefore a detector adapted to the reality inside a ventilation duct

    When the special properties of infrared technology and the unique dual measuring chamber are combined the result is reliable refrigerant detectors for early detection and avoidance of false alarms.

    The detector has a life expectancy of over 10 years and needs only supervision every 5 years.

    A key concern in designing the detector was how to reduce the number of recalibration and service calls caused by the operation etc., in relation to conventional refrigerant detectors without sacrificing sensitivity. Annual service inspections are no longer needed with the new infrared technology.

    Costs for operation and maintenance are hereby reduced.

    New 0-25% Oxygen Sensor
    Oxygen detectors are important in all environments where hypoxia may occur.
    This includes:

    • Liquid nitrogen storage ("cryorooms"), which has pressurized nitrogen

    • Test vessels for vacuum

    • Licensed and enclosed spaces

    • Workplaces containing pressurized gases which may displace oxygen

    Oxygen Sensors are also used to detect leaks inside sealed glove boxes used in scientific processes and in industrial manufacture of light bulbs.

    Unexpectedly poor air quality in new houses - create safe air

    Tenants fall ill despite the increased use of natural materials.

    Installation of air quality sensors would improve the ventilation and exhaust ventilation of VOC (volatile organic compounds).

    The substances that come from building materials could make people sick.

    Just before people move into a building for the first time, the concentrations of volatile organic compounds, VOCs, in indoor air is up to eight times higher than what the industry benchmark states.

    After about three years, the concentrations have gone down but are still twice as high as the benchmark.

    The volatile organic substances come from wood and linoleum, materials which have become increasingly common in modern homes.

    The volatile organic substances also come from floors and countertops that are regularly oiled.

    Using a natural material is no guarantee that you get low concentrations in indoor air.

    Even less natural solvents from glues, paints and cleaning agents are commonly found in indoor air.

    It is not enough to check emissions from the individual building materials.

    You must also check the emissions in the new buildings before people move in.

    It is mainly terpenes that dominate the indoor air.

    These substances are found naturally in wooden materials and linoleum carpets.

    Research has shown that terpenes can react on nitrogen oxides and ozone to form the so-called free radicals, which are highly irritating to mucous membranes.

    The substance is obtained from lemon peel and is suspected to be allergenic.

    It is often used as lemon scent in common solvents.

    Even n-butanol from water-based glues and paints, as well as aldehydes occur in unexpectedly high concentrations in indoor air.
