Introduction
WHY USE EVAPORATIVE COOLERS IN YOUR WORKPLACE?
•
The WayCool
®
evaporative cooler requires little space, has a low initial cost, is inexpensive and simple to operate 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. (Approximately two seasons)
•
In many cases, evaporative coolers are a better solution than mechanical refrigeration systems because they are more economical
to operate and maintain and do not use environmentally sensitive and costly refrigerants.
HOW EVAPORATIVE COOLING WORKS
Figure WC-1HP.02 - Evaporative Cooling Principle
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 them and a fan moves the
air. The air blows across 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 out 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, a
WayCool
®
portable evaporative cooler can lower the effective air temperature by up to 20°. Even in high humidity, the efficiency of the
WayCool

evaporative cooler provides effective cooling.
