Evaporative
cooling works on the principle
of heat absorption
by moisture evaporation.
Your evaporative
cooler draws outside air into specially
made pads soaked with water, where the air is
cooled
by evaporation,
then circulated
into your home.
Your MasterCool
evaporative
cooler has been designed
to provide more efficient,
consistent
cooling
through
use of a long-life MasterCool
pad. It is a cellulose fiber treated with stiffening and wetting agents
to provide the most reliable evaporative
pad ever devised.
Your cooler
has two modules
- wet and dry - which may be separated
for service and cleaning,
and
incorporates
the most reliable components
for long, trouble-free
life.
