Evaporative Coolers

An evaporative cooler (also known as swamp cooler, desert cooler or wet air cooler) is a device that cools air through the evaporation of water. These units are well suited for climates where the air is hot and humidity is low. They combine the natural cooling properties of water with a steady breeze to lower indoor temperatures. Evaporative cooling will provide substantial energy savings over other refrigerated air units, while the simplicity of the design results in low maintenance requirements.

With the substantial savings of energy and the constant changes in the air, a swamp cooler is ideally suited for area cooling or spot cooling of rooms, homes, factories, laundries, churches, schools, agricultural/business areas, restaurants, and more. We offer an extensive range of swamp coolers that are available today.
