Evaporative Cooling
Evaporative cooling uses the principle of evaporation to lower the air temperature. Hot, dry air is passed through wetted
filters and is converted to refreshingly cooled air. Essick Coolers make the best use of the evaporative process by
controlling the flow of water, spreading the water evenly over the filters, and keeping a steady stream of cooled air
entering your home. It is exhausted out open windows or doors, carrying heat, smoke and odors along with it. Essick
evaporative coolers are 80% less costly to operate than refrigerated air conditioners.
Cautions:
To prevent harm to yourself and others, and to avoid damage to your cooler, PLEASE follow these guidelines.
