The IND-HVAC-DTW-UVC-R6-SS-18-4L-N3R-208V from Larson Electronics is a High Output Air Duct Disinfection System that works to disinfect air moving through a duct system via germicidal ultraviolet (UV) rays. This unit helps to control the spread of airborne cold and flue virus as well as other airborne transmitted disease. This anodized aluminum air duct disinfection system features four of 15 watt UV bulbs that each produce 5.3 watts (21.2W total) of UV output at a wavelength of 254nm. The IND-HVAC-DTW-UVC-R6-SS-18-4L-N3R-208V is designed to be mounted inside an air duct and operates on 208V AC current. This unit can be installed on rooftop duct units with a gasket mount, outdoor rated indicator light, and NEMA 3R rated ballast enclosure.
*Please note: This product produces UV light. Make sure to follow all safety guidelines and protocols found in the user manual.
The IND-HVAC-DTW-UVC-R6-SS-18-4L-N3R-208V is a powerful sanitation solution for industrial sites and commercial facilities. Equipped with four UVC fluorescent lamps, this system offers 21.2 total watts of UV output at a wavelength of 254nm. The lights have an expected lifespan of 8,000+ hours and emit a flood beam pattern. The IND-HVAC-DTW-UVC-R6-SS-18-4L-N3R-208V can be used continuously in air ducts such as those found in HVAC systems.
This high output UV air duct disinfection system projects ultraviolet rays inside the air duct it is mounted in. The air flowing through the duct that passes through the UV rays is then sanitized. Bacteria and viruses present in the air that passes through the UV rays produced by the fixture are destroyed. The air moving through the duct is constantly being purified as it flows through the UV rays being produced by the fixture.
The enclosure of the IND-HVAC-DTW-UVC-R6-SS-18-4L-N3R-208V is built from 304 stainless steel. In-Operation and Replace-Lamp indicator lamps allows for operators to check the status of the UV bulb(s) without removing the fixture from the air duct or being exposed to harmful UV radiation.
The IND-HVAC-DTW-UVC-R6-SS-18-4L-N3R-208V is designed to be mounted inside an air duct. The system is intended to be mounted in a partial internal style with the bulb(s) being mounted inside of the air duct and the electronics mounted on the outside of the duct.
The IND-HVAC-DTW-UVC-R6-SS-18-4L-N3R-208V can be mounted on rooftop ducts and HVAC units. The design of this air duct disinfection system requires the ballast box to be mounted outside of the duct. For rooftop units, the externally mounted ballast box will be exposed to the elements. The IND-HVAC-DTW-UVC-R6-SS-18-4L-N3R-208V features a NEMA 3R ballast enclosure along with a gasketed mount between the ballast enclosure and mounting surface to keep moisture out. The indicator light is also outdoor rated.
Note on Environment:
Sunlight and visible light fixtures do not impact the effectiveness of the disinfecting on this UVC sanitation product. Metal halide, high pressure sodium, fluorescent, and LED light fixtures can be left on. The UV radiation emitted from this product is not disrupted by any type of lighting in the environment. Put simply, NO it DOES NOT need to be dark in the area you plan to disinfect. The UV radiation is harmful to the eyes and skin, and that is why you should not be in the area while it is in operation. Please see user manual for additional safety information.
This ultraviolet UV air duct disinfection system can be used to continuously disinfect air of mold, allergens, airborne bacteria, viruses, and germs. The IND-HVAC-DTW-UVC-R6-SS-18-4L-N3R-208V is ideal for use in restaurants, hospitals, clinics, laboratories, nursing homes, schools, food processing facilities, office buildings, conference rooms, universities, clean rooms, and many more.
