Why use PhotoHydroIonization?
Germicidal UV light rays have been used for decades by the medical industry as a method for destroying microorganisms (germs, viruses, bacteria). UV light is dependable and can be easily installed in HVAC ducts or a plenum. Germicidal UV light is effective in reducing airborne microorganisms that pass through the light rays. However, germicidal UV light has little to no effect on gases, vapors or odors.
Ozone, on the other hand, is very effective on gases, vapors and odors. However, too much ozone can be a health hazard, and traditional methods of producing ozone (corona discharge) have maintenance problems and create nitric acid and nitric oxides. The combination of ozone (O3) and UV light in the presence of the PHI catalyst creates the Advanced Oxidation reaction.
This patent pending reaction chamber both creates ozone gas and destroys it within the same chamber. This process in combination with the catalytic target surface of the cell produces not only an atmosphere in which germicidal light can kill micro-organisms. It also produces, super oxide ions and hydro-peroxides. These products of advanced oxidation reactions further attack the microorganisms as well
as significantly reduce odors and VOC’s. The PHI reaction cell has the added benefit of producing safe low levels of ozone as a by-product to the PHI cell. This low level ozone further cleanses the air as it travels down the ductwork. By engineering the proper light wavelength and a dual function, no maintenance PHI Cell, RGF has effectively designed a system that will not exceed the recommended Federal safety limits for ozone (0.04 ppm) in an occupied room.
With the RGF PHI CELL, most gases and odors are abated while micro-organisms can be reduced by as much as 90%, and the room will have safe low ozone levels no greater than forest air or air after a thunderstorm, which will give the room fresh, clean and odor-free air.
