GENERAL CHARACTERISTICS OF OZONE
NATURAL AND EFFECTIVE CLEANING
Ozone is a naturally occurring gas in nature, a simple molecule consisting of three oxygen atoms. It is a natural, colourless or light blue gas with a characteristic smell. The smell, which resembles that of chlorine, can be noticed during passing thunderstorms because ozone is in fact formed by the atmospheric electrical discharges we call “lightning.”
MANY AREAS OF APPLICATION
Ozone can be used in various application areas such as air exhaust treatment in commercial kitchen environment. Please contact us for more information on the application areas of ozone.
Local jurisdictions have maximum exposure limits for indoor environments. For example, the hygienic ozone limit value in Sweden is:
- NGV (threshold limit value) 0,1 ppm (applies for exposure during a workday, i.e. 8 hours).
- TGV (celling value) 0,3 ppm (applies only for a reference period of 15 minutes).(Pursuant to AFS 2005:17, Occupational Exposure Limits and Measures against Air Contaminants).
Extended exposure to ozone in higher-than-normal concentrations can be dangerous, causing irritation to eyes, lungs and skin. Important to keep in mind, however, is that with AirMaid products used within exhaust ventilation systems the ozone is present only in the duct airstream being sucked out of a facility at a negative pressure. When combined with safeties in our equipment and its installation requirements, the chance of any human exposure at levels higher than that found in nature is nearly null.
THE OZONE LAYER
Without ozone we could not survive. The ozone layer is present in the top of our atmosphere which protects the Earth, both from harmful UV radiation and from it becoming too warm.
