UV Resources - Model DLX-N -Dual Lamp High Output UVC Fixture for HVAC Disinfection

FromUV Resources, LLC, formely known as Steril-Aire, Inc.

The DLX-N Dual Lamp High Output UVC Fixture is designed specifically for UV-C disinfection in HVAC/R systems such as cooling coils, drain pans, return/supply ducts, and rooftop units. This fixture features a NEMA-4 rated enclosure, making it suitable for both indoor and outdoor installations, and it can be accessed and serviced from the exterior of installation sites. It comes with dual high-output UV-C lamps that provide a 360-degree disinfection radius, effectively inactivating pathogens like SARS-CoV-2 in various airstreams. The unit's construction includes heavy-gauge galvanized steel housing with a powder-coated finish and is equipped with a waterproof power supply operating at temperatures of 1–70°C (33-158°F). The fixture uses non-proprietary, high-output UV-C lamps that emit broadband UV-C wavelengths between 250-260 nm, ensuring robust microbial inactivation. Each lamp is coated with EncapsuLamp for added protection and a minimum useful life of 9,000 hours. UL listing for safety requirements is pending, and the fixture also contributes to improved HVAC efficiency and reduced energy use by maintaining clean coils and optimal heat transfer.

Designed for a full range of new or retrofit infection prevention applications, the DLX-N can be easily installed indoors or outdoors in most light-commercial, commercial, industrial and healthcare HVAC systems, as well as return or supply duct runs and RTUs.

The antimicrobial fixture delivers the necessary germicidal dose to inactivate pathogens in virtually any airstream and its NEMA-4 outdoor rating makes installation possible on any exterior return, supply or exhaust duct.

Like most germicidal fixtures installed near HVAC cooling coils, the DLX-N can improve heat transfer efficiency, reduce energy use and lower maintenance costs. With lamp sizes ranging from 12- to 31-inches, the DLX-N lamps provide 360-degrees of high UVC intensity. The UVC fixture provides a versatile means of inactivating airborne pathogens on almost any inside or outside duct.

Fixture are factory-assembled and tested and feature a powder coated, galvanized steel NEMA-4 housing, a “waterproof” power source, LED lamp/power supply monitor and two high output UV-C lamps. Construction is designed to withstand outdoor or indoor applications.

Housing is constructed of powder coated heavy-gauge galvanized steel with 1 – 1/2″ conduit knockout on the fixture’s base for hard-wiring, or an appropriately size hole can be made with a step-down drill bit to allow for a waterproof conduit connection. The fixture is designed to be mounted and serviced from the exterior of its installation site; such that, the lamps protrude into the plenum or duct. It can be externally mounted anywhere in an HVACR system, ducts or as shown on system plans.

Power Supply is a waterproof, Type 1, outdoor, high-power factor, electronic rapid-start type with overload and end-of-lamp-life circuit protection that maximizes lamp radiance, life, and system reliability at temperatures of 1–70° C (33-158°F). Input: 120-277Vac, 50/60 Hz, with a sound rating of A.

Sockets are standard 4-pin types constructed of a UV-C-resistant polycarbonate for long life.

Lamps are non-proprietary, single ended, very high output, hot cathode, T5, O8 4 pin, base types that produce broadband UV-C between 250–260 nm. Lamps are coated with EncapsuLamp™ (FEP) for protection in case of accidental breakage. UV-C lamp produces the specified output at any airflow velocity and temperatures of 1-77° C (33-158°F). Lamps are standard non-ozone producing types. Minimum useful lamp life is 9,000 hours, with no more than a 15% output loss, depending on conditions.

Independent Testing is in conformance with all safety requirements of Underwriters Laboratories (ABQK). UL listing pending.
