The unit consists of up to 4 compact UVC lamps, a transformer and a mounting enclosure. Units are normally installed downwind of the air handler but the ACP can also be positioned upwind of the air handler to act as a coil sterilizer. Th.Standard" units consist of the 16" and 36" options and each option is available in 1, 2, 3 and 4-lamp units. There are 2 output options and please note that there is a Standard Series and a High Output Series. The Standard ACP Series is available in 120-V/60 Hz and 220/50 Hz and is available in 16" 36" sizes. The High Output ACP Series is available in 120-V/60 Hz and 277/60 Hz and is available in 12", 16", 24", 36" and 48" sizes. Unit sizing is based on the velocity of the air stream in the duct and we can assist with sizing the unit suited for your project. Please contact us with any questions relating to the utilization of this type of fixture to sterilize air routinely cycled by your air handling units.
