Air from behind the evaporator passes by a germicidal class 254
nm UVC light and is sterilized. Then a 185 nm UVV light acts on
the oxygen and water vapor in the air stream as it passes by the bulb
to create photoplasma. Cold Oxygen Plasma is a gas that is ionized
by UVV light containing ions, free electrons, hydroxyl radicals and
ozone. Each of which is highly reactive with the microorganisms it
encounters in the foodzone. This active air is continually recirculated
within the foodzone, inhibiting virus and bacteria growth.
