Welcome
to the December edition of Steril-Aire's UVC E-Newsletter. In each issue, we will
address an important question about ultraviolet-C or "UVC" devices for
building HVAC systems. Steril-Aire
will also be happy to provide you with a free on-site evaluation on how to equip
your building(s) for energy, mold, IAQ and infection control using UVC technology.
If you would like to know more, contact

Can UVC devices installed in the air handlers help control problems with indoor
odors? A.
Yes, definitely. If mold or mold-related allergens that grow in or circulate through
the air handlers are the cause, UVC devices - installed opposite the cooling coils
- can be very effective in stopping such odors. Many users report that musty indoor
smells are replaced by a refreshing, clean-air scent within a short time after
UVC is installed. Odors
caused by different types of contaminants are best handled case-by-case and may
require a combination of UVC and other technologies. This was the strategy at
the Hyperion Wastewater Treatment Plant (Los Angeles), where the Pregerson office
building was experiencing complaints about poor IAQ and odors. An engineered solution
that incorporates an odor control unit and supplemental UVC lights in the air
handling systems has solved the problem and earned the project semi-finalist status
in the City's prestigious Quality and Productivity Awards program.
The odor control unit contains
three banks of activated carbon filters for H2S removal and two stages of air
filtration for capture of particulate contaminants. To provide added insurance,
high-output UVC lights are used at the cooling coils in the existing air handling
units that serve the building.
Daniel
Strauss, P.E., mechanical engineering manager for the Environmental Engineering
Division (EED), Bureau of Engineering, City of Los Angeles Department of Public
Works, comments: "The UVC lights add an extra dimension of protection, and
we believe the benefits exceed the cost. We believe UVC technology has broad application
for all types of buildings, and have recommended that it be incorporated into
the Bureau of Engineering master specifications for all our HVAC equipment."
