UVC for HVAC
Double-Ended, Very High
Output Germicidal Light
Source for HVAC Systems
Steril-Aire's multi-patented UVC Emitter™ provides the
best and longest-lasting UVC performance available. As
shown in the comparison graph (above) , it has been
independently tested to deliver an average of 5 times the
output of other ultraviolet devices under HVAC operating
conditions (45 o F @ 550 fpm air velocity).
Competitive UVC lights must be changed every 3-4
months because they quickly lose the output or "killing

power" needed to maintain microbial control. The UVC
Emitter, by contrast, has a 12-month service life – and even
after a full year, it has 2-1/2 times greater output than
competitive devices deliver on Day 1! As a result, only Steril-
Aire can ensure the germicidal performance you need, with no
return of microbial growth, for 3-4 times longer than the
competition.
Applications
Steril-Aire Double-Ended (DE Series) fixtures are used
for internal installation in medium to large air handling
systems in commercial, industrial, health care and institutional
buildings. They may be mounted singly, in built-up banks or in
parallel configurations in a variety of locations, including
coils, drain pans, ductwork, mixed air plenums and exhaust
systems. The DE Series is available in five lengths (18", 24",
30", 36" and 42") and four voltage options (115, 208, 230 or
277 Vac), providing installation flexibility to accommodate
virtually any system.
Benefits
• Kills or inactivates surface and airborne microorganisms that
contribute to poor IAQ and/or the spread of infectious disease,
including: mold and mold spores, bacteria (including TB ,
Legionella, E. coli, Listeria, salmonella, and whooping
cough) ; and viruses (including colds, flu, measles ).
• Delivers an average of 5 times the output of competitive UVC
products at HVAC operating temperatures, for 3-4 times
longer life and more reliable germicidal control.
• Uses patented state-of-the-art solid-state electronic power
supply for enhanced reliability and performance.
• Continuously cleans coils, drain pans, plenums and ducts,
eliminating costly cleaning programs and the use of harmful
chemicals and disinfectants.
• Lowers HVAC energy costs by restoring heat transfer and net
cooling capacity.
• Produces no ozone or other secondary contaminants – will not
harm building occupants, equipment or furnishings.
• Offers lowest life-cycle cost of any UVC product. Return on
investment is often less than one year.
• The most widely used product for commercial "UVC for
HVAC™" – the industry standard!
