Details
Ozone treatment of indoor air is now a very common, widely used air purification and disinfection process. Our devices use VUV light for ozone production, rather than corona discharge. We do not need to use air preparation systems (air dryer or oxygen concentrator) that require extra costs and maintenance. The UV ozone generator, unlike the corona discharge generator, does not produce harmful nitrogen by-products and works extremely well even in humid air. In our case, the electrons connect the ozone molecule in bonding molecular orbital, while in the case of corona discharge, they mostly circulate in an anti-bonding orbital. In the latter case, ozone molecules do have higher energy, but they can be dangerous, as they can exert their decomposition properties unexpectedly and with great force even where we did not expect it. The main advantage of ozone compared to other treatment methods for air disinfection is its ability to treat efficiently large air volumes. A gas that can reach every corners of the room, so it can disinfect the entire room effectively. It is characterized by very strong oxidizing and good penetration ability. As ozone gas is unstable, unreacted ozone converts quickly back into its original form, oxygen (O2), leaving behind no harmful by-products after the disinfection. It is recommended for use in apartments, industrial buildings, restaurant kitchens, doctor’s offices, changing rooms and gyms, food storage rooms and all rooms where there is a need for clean air free of pathogens and unpleasant odors.

Functional principle

Large amount of ozone is produced in the reactor chamber from the oxygen content of the ambient air using VUV lamps tuned to a wavelength of 185 nm:

O3en
Single oxygen atom (O) is formed by the photolysis when the Vacuum UV radiation at 185nm splits the oxygen molecule (O2) into two oxygen atoms. It then easily combines with an oxygen molecule (O2) to form ozone molecule (O3). Ozone is an unstable molecule due to a weak bond holding the third oxygen atom. This instability naturally makes ozone a powerful oxidizing, disinfecting and deodorizing agent. Oxidation occurs when ozone molecules come into contact with oxidizable substances, including microorganisms (pathogenic bacteria, viruses, and mold), and organic and inorganic compounds. Some examples of the deodorizing effect of ozone:

Formaldehyde (CH2O) called cause of a “new-building disease”:
CH2O + 3O3 = CO2 + H2O + 3O2
Smell of rotten eggs (hydrogen sulfide H2S):
H2S + O3 = SO2 + H2O
Smell of toilet (ammonia NH3):
2NH3 + O3 = 3H2O + N2

The radiation of the used VUV lamps (185nm + 254nm) not only allows ozone production, but also irradiated UV-C light at 254nm, have a strong germicidal, i.e. disinfecting, bactericidal effect. The synergistic combination of 185nm and 254nm radiation is very effective on the destruction of bacteria and viruses. After entering the amount of ozone applied to the room to be treated, after completion of the timed treatment process, the ozone generating lamps are automatically switched off, only the fans remain in operation to help degrade the residual ozone not used in the treatment. The ozone produced by the R-FILTER, if not involved in treatment operations, converts quickly back into its original form, oxygen (O2), with a half-life of up to 30-50 minutes and leaves no harmful residual. The higher the temperature and humidity of the room to be treated, and the more dynamic the air flow, the shorter the half-life and the sooner we can enter the treated room. After the treatment is completed, the unit will run the fans for another 4 hours, increasing the degradation of the residual ozone not used in the treatment. If you then enter the treated room, you must immediately ventilate it well.
