PRODUCT APPLICATION

CONSTRUCTION

The

 

Air Duct Disinfection Unit consists of:

Germicidal Ultraviolet Lamps, which deliver ultraviolet energy in the specific wavelength of 254 nanometers (nm)

 

which effectively destroys airborne microbes including: virus, bacteria, and mold spores.

Units use Electronic Ballasts available in 120v 50/60Hz

Units are equipped with a cord whip and flying leads for users to install their own cord cap, or for hardwired 

applications.

All electronics and wiring are housed in an enclosure constructed of stainless steel. Stainless steel construction

 

provides strength, durability and will withstand most harsh environments.

PRINCIPLE OF OPERATION

The design has been carefully conceived to provide adequate germicidal ultraviolet dosage for air stream or surface 

disinfection in new or existing HVAC(Heating, Ventilating & Air Conditioning) Systems. The dosage, as it applies to 

ultraviolet disinfection, is a function of time, and the intensity, of ultraviolet radiation, to which the air stream or surface 

is exposed. The exposure time, in seconds, is the total time it takes the air to move through the ultraviolet field, 

produced by the germicidal lamps. Exposure time is related to the airflow rate; the higher the airflow, the lower the 

exposure time or the lower the airflow, the higher the exposure time. The UV intensity is the amount of energy emitted 

by the germicidal lamps.

Air moving in the HVAC System duct passes over the germicidal ultraviolet lamp of the Air Duct Disinfection

Systems and is exposed to the ultraviolet rays emitted by the germicidal lamp.

LIMITATION OF USE

The Air Duct Disinfection Systems requires professional installation so all wiring complies with applicable state,

local and national electrical and mechanical codes.

The Air Duct Disinfection Systems requires knowledgeable planning for: location, installation, and supervision to

prevent ultraviolet exposure of occupants.
