GAS DETECTION - OZONE (O3) - INDUSTRIAL

 

Ozone
This gas is toxic and a health hazard when it occurs at ground level (ground level ozone), but high up in the atmosphere it fills a vital role as a filter of harmful UV radiation.

Ground-level ozone (also known as tropospheric ozone), is ozone near the earth's surface.

In the stratosphere, at over ten kilometer´s altitude, ozone protects against the sun's dangerous ultraviolet rays, but it is harmful to plants and animals living in the lowest part of the atmosphere.

Ozone prevents the photosynthesis from taking place and damages the water balance of plants, and reacts with the mucous membranes of the respiratory tracts.

Ground level ozone is for instance formed when sunlight meets exhaust fumes from cars.

It also produced in photocopiers.

Ozone is a natural greenhouse gas needed to purify the air at ground level.

In the photochemical process, for example, when the sun's UV rays hit oxygen (O2), free oxygen is produced (O), and ozone (O3).

 Ozone oxidizes contaminants very quickly and often breaks them down into carbon dioxide and water.

The decrease of ozone in the atmosphere (due partly to the increased industrial emissions) has in recent decades led to the so-called ozone holes appearing over the earth's polar regions (Arctic and Antarctic).

Technical use
Ozone is chemically very aggressive and has a relatively high technical
use.

It can be used, for instance, to achieve extremely fast and effective bleaching of chemical pulp, and for sterilization of water. One problem with the technological use of ozone is its instability.

It must therefore be produced on site.

Ozone is sometimes used to remove odors.

Common uses are:

  • Preparation of drugs and synthetic lubricants, where the function of the ozone is to break the carbon-carbon bonds.

  • Bleaching of pulp and textiles.

  • Disinfection of air and water since the ozone kills mold spores, bacteria and microorganisms.

  • In many parts of the world use ozone instead of chlorine is used to purify municipal drinking water.

  • Ozone forms no organic chlorine compounds and is not left in the water after the cleaning process.

  • Disinfection of washing in hospitals, medical facilities and in the food industry.

  • Killing of bacteria, yeast, mold and insects on food as well as in stores for corn.

  • Elimination of odors in furniture that has survived fires but still smells of smoke. In such cases a so-called ozone chamber is used.

Choice of Equipment

The Stand-alone detector is a detector where power supply, alarm and control functions are integrated in the detector housing. This detector is used where very simple systems are sought and only few monitoring points are desired.

The exchangeable sensor X-CHANGE turns the recalibration into a home game:

  • Delivery of recalibrated sensor cartridges

  • Easy exchange, no specialized company needs to come to you

  • Available for every gas type

  • At guaranteed exchange prices

  • Increased reliability (SIL2-software)

  • Important time and cost savings

The X-Change support guarantees a price based on the consumption of the sensor capacitance.

For each uncalibrated sensor returned to AP, you will receive a credit for the unused capacity of the sensor.

Legal and safety requirements
The devices are manufactured according to the regulations and various directives such as EN 50545, etc.

Products delivered by AP meet and even exceed the new European Standard EN 50545.

The safety features check the connected warning devices on functionality and open circuit day and night (Level SIL2 according to EN 50271).

   

Quick and easy replacement of sensor

  1. Open the housing with a screwdriver.

  2. Disconnect the sensor cable and unscrew the disused sensor head.

  3. Exchange the sensor cartridge (3) and connect the cable of the new sensor head to the PCB.

  4. Close cover of the housing with the screws (1). The recalibrated sensor is ready for use at once.

 

Electrical products in an explosive environment
A small amount of energy - a flame, spark, high surface temperature or similar is required to ignite an explosive gas mixture.

Products installed in an area with a potential explosion hazard must of course in themselves  not be a potential explosion hazard.

For this reason, the products are manufactured in such a way that this cannot occur.
The equipment must also be labeled and tested - ATEX classified - by the approved testing authority.


The Ex-class information is available in "Swedish Standard"
The choice of which Ex-classification is required is determined by factors such as type of gas, permissible maximum surface temperature and potential explosive hazards in the area where the products are to be installed.

The potential explosion hazard in the different areas is determined by the zone classification according to "Swedish Standard".
