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 and is expected to
prolong the life on mechanical
equipment
Potential Horse power savings
should not be ignored especially
for those who utilise VAV drives |

The Florida
Hospital Group

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
£3,300
on an investment of
£2,000.00
The hospital is
conservatively saving 15% in
HVAC system energy costs |

Hospital

Before UVC
The
chillers serving the hospital
were running at 99% capacity
Chilled water “in” measured at
43°, while Chilled water “out”
measured at 64°
After UVC
The same
chillers were running at only
62% capacity
Chilled water “in” remained at
43°, but chilled water “out”
temperature had decreased to
53°, an 11 degree drop
Electrical
usage (in kilowatt hours)
declined by 20.64%
This essentially cancelled out
an equivalent rise in utility
rates from $.06 per kWh to $.08
per kWh

Reductions
in air changes resulted in
decreased heating costs
We have saved more than
£47k in
natural gas by reducing our
outdoor air requirement
Even after
we subtract for servicing and
changing UVGI lamps, annual
savings still exceed
£37k |

“In addition the perpetually clean coils
are more energy efficient. Between the
maintenance and energy savings the
lights definitely pay for themselves.”

"Before the UVGI emitters were
installed inside the air handling units,
Queen’s had to clean and disinfect air
conditioning coils and drain pans
annually. The areas are inspected every
three months but since UVGI was
installed a year ago, no slime has grown
and the system is operating at nearly
100% efficiency."

Interview with Robert Scheir, president
and chairman, Steril-Aire
The electromagnetic spectrum offers
considerable potential to prepare and
preserve food products. The application
of UVC, short-wave ultraviolet in the C
band range (200 to 280 nanometers) to
inactivate mould, bacteria, fungus,
viruses and other spoilage organisms
illustrates the development challenge.

"The product has been shown to work
against viruses, bacteria, mould and
mould spores. Because the five-story
ASPCA building includes extensive animal
housing and the Bergh Memorial Animal
Hospital, a full-service small-animal
medical facility, any technology that
helps prevent the spread of infection is
of importance."
"After
Eco-Care installed lights in the
existing AHUs, Grujic said he quickly
noticed a big improvement in system
efficiency."
“During the summer of 2005, one of our
hottest summers on record, we were
actually getting complaints that the
building was too cold."
“After looking into the reasons, we
found that the temperature at the coil
of our 90-ton AHU was as low as 47˚,
about a 10˚ drop from our usual
readings,” he said. “We had to turn up
the set point to compensate."
