Bacteria control without
using toxic chemicals
How
the system works
The cooling tower unit
contains it own circulating pump, which draws
water from the cooling tower basin and passes
it through a sand filter, then through the UV
unit and back into the cooling tower basin. Back
washing of the sand filter is done automatically
by a fully programmable digital timer using solenoid
valves, although it can be done manually if required.

The
advantages:
- It can run 24 hours
per day, 365 days per year while giving a consistently
high level of protection from infestations,
such as Legionella pneumophila, which causes
Legionaires disease.
- Quick and easy installation,
often without needing to shut down the cooling
tower.
Small
enclosed units
UVTA
model numbers CT LC30, CT LC80 and CT LC110. The
unit includes pump, UV unit, programmable digital
timer, automatic back wash sand filter, interconnecting
pipework and wiring, back wash water tank and
central inlet power point. All equipment except
the filter, are mounted inside an enclosure. Also
available are; TDS monitor control systems and
test kits.
Large
enclosed units
UVTA
model numbers CT52L, CT100L. The unit includes
a pump, UV unit, programmable digital timer, automatic
back wash sand filter, interconnecting pipe work
and wiring, TDS controller, chemical injection
pump, test kits, back wash water tank and a central
inlet power point all mounted inside a roller
door enclosure.

Correctly sized UVTA
Ultraviolet Disinfection Systems can be easily
incorporated into the existing basin. Water volume
is calculated and UV unit sized in order to turn
over the entire volume of water every 10-60 minutes.
A circulating pump takes water from one side of
the basin, passing through a filter, then through
the UV unit, and the disinfected water is returned
to the opposite side of the basin.
