Introduction
WHY USE EVAPORATIVE COOLERS IN YOUR WORKPLACE?
*
Evaporative coolers take up a small area within the building, have a low
initial cost, are economical to run, ease of operation and requires minimal
scheduled maintenance.
* Due to the design and construction of the cooling pads, cooling efficiency
is normally maintained near optimum throughout the life of the pads.

HOW EVAPORATIVE COOLING WORKS
Evaporative cooling is the same process your body uses to cool itself. When
you perspire, and air moves across your skin, a portion of the perspiration
(water) evaporates. Evaporation requires heat to change liquid water-to-water
vapor and this heat is taken from your skin, producing the cooling effect.
In an evaporative cooler, the cellulose cooling pads take the place of your skin,
water instead of perspiration wets the cooling pads and a fan moves the air.
The air is drawn through the cooling pads and evaporates moisture. Heat is
drawn from the pads and the air, dropping the air temperature and producing
the cooling effect. The cooled air is then forced through a building or space
and displaces the warm air from the building openings, cooling the
surroundings. In addition, air velocity increases the cooling effect as it moves
over the skin of people in the airflow path.
Evaporative coolers are portable and use the latest technology to provide
large volumes of cool air, efficiently and inexpensively for cooling small to
medium size areas. Simply adding more units can accommodate larger areas.
With proper sizing and application, an evaporative cooler can lower the
effective air temperature by up to 160°C.
