DLX-N Dual Lamp HO UVC Fixture

Ideal for RTU or In-Duct; NEMA-4 Enclosure

The DLX-N high output, dual lamp ultraviolet NEMA-4 fixture efficiently disinfects HVAC/R airstreams, cooling coils and drain pans halting infectious diseases such as the SARS-CoV-2 virus.

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.  Also ideal for roof top units.

Specs and Certifications

Lamps included with this fixture provide an average of 9,000 hours of operation.
Input power voltage configuration.
Primary disinfection mode: Air & Surface, Air or Surface.

Product is free from defects in material and workmanship from the date of first purchase.

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.
