Enhanced Single Ended NEMA (ESEN) by Steril-Aire


Steril-Aire’s Enhanced Single Ended NEMA fixture brings outdoor ease of installation to the company’s line of high-performance UVC for HVAC™ systems.

The ESEN fixture combines the externally mounted design of the ESE Series with a weather resistant NEMA 4X housing.

The ESEN supports Emitters TM up to 61” in length from an easy to install fixture that mounts on the outside of the unit. Maintenance of the Power Supply and Emitter change outs are simple and accessible without disruption of the AC Unit operation.

The ESEN provides an ideal solution for rooftop AHUs. By creating two 1” holes in the equipment wall and mounting the fixture, only the Emitter penetrates the system, while the power supply remains external. The ESEN Series supports lamps in eight lengths:

  • 16”
  • 20”
  • 24”
  • 30”
  • 36”
  • 42”
  • 50″
  • 61”
