Our UVGI for HVAC technology
delivers 10-20% in energy savings.
Below are the
methods used. 
Method 1.
Perpetually Clean Cooling Coils.
A degradation in cooling coil
performance is caused by:
 |
Forcing
air through very confined
spaces in air
conditioning coils.
The average amount of fins-per-inch
in a cooling coil
is twelve but can
increase in ever smaller
a/c systems creating a
very restricted space
for large volumes of air
to move.
|
|
|
The
spaces between a/c fins
is an ideal breeding
ground for bio-films to
grow (mould and
bacteria),
blocking the free flow
of air.
|
|
|
Mechanical cleaning
methods damage the fins
and don't work because
they push bio material
into the middle of the
coil causing a reduction
in heat transfer to the
fins.
They are also a
temporary fix as
bio-films grow back with
in weeks until the next
clean which is normally
months apart.

Case Studies
Boston University
“In addition the
perpetually clean coils are more
energy efficient. Between the
maintenance and energy savings
the lights definitely pay for
themselves.”
 Case Study
American
Electric Power
 |
“Estimated saving of
$139,000 in annual energy
costs in 2 + years”. |
|
“Amounted to 15% savings.” |
| “Cut back
from four 300-ton chillers
to two.” |
Case Study
Southern
California Air Conditioning
Distributors
(The worlds’
largest Carrier distributor)
| “The
pressure drop across the
coil decreased by over 30%.” |
|
“The airflow increased from
16,000 CFM to 17,400 CFM.” |
| “30%
increase in cooling capacity
from 548,502 BTU to 797,094
BTU.” |
|
“The devices ability to
increase system performance
to almost “as new” levels is
expected to prolong the life
on mechanical equipment“. |
|
“Potential Horse power
savings should not be
ignored especially for those
who utilise VAV drives.” |
Case Study
Florida
Hospital
| “Within
weeks of installing the UVC
the air velocity across the
coil more than doubled from
230 fpm to 520 fpm.” |
|
“The wet bulb temperature
decreased from 57°F-53°F.” |
| “We
calculated the increase in
capacity to 95,245 BTU
saving $4,867 on an
investment of $2,000.” |
|
"The hospital is
conservatively saving 15% in
HVAC system energy costs.” |
Case Study
Method 2.
Enabling more air to be
re-cycled.
Many engineering professionals
know that this can cause IAQ (Indoor Air Quality)
(indoor air quality) problems
leading to a rise in staff
infections.
In this scenario our UVGI for
HVAC systems act as a counter
weight, sterilising the recycled
air thus offering a significant
energy saving, please see our
latest case study.
Tacoma Jail
|
“Reductions in air changes
resulted in decreased
heating costs.” |
|
“We have saved more than
$70,000 in natural gas by
reducing our outdoor air
requirement” |
| “Even
after we subtract for
servicing and changing UVC
lamps, annual savings still
exceed $55,000.” |
