AIR DISINFECTION – PHOTOCATALYTIC OXIDATION (PCO)

UV light is applied to a metal oxide semiconductor material surface (typically titanium dioxide), super oxide and hydroxyl radicals are generated in the airstream. These highly reactive radicals and ions decompose organic compounds (VOC’s and pathogens) and turn them into CO2 and H2O. In short PCO deactivates bacteria and turns odors into air and water. • Possible by-products formed by incomplete oxidizing like formaldehyde, acetaldehyde, formic acid and acetic acid. Manufacturer data and published test results to be considered carefully. • Has been utilized in different applications with a proven track record. • Has a very low pressure drop (0.05” @ 500 fpm) • AHU retrofit options available with minimal space impacts.
