Evaporative Coolers

Evaporative Coolers Get Rid of the Humidity

Evaporative coolers use filtered fresh air from the outside to cool an interior space. Using fresh air enables evaporative coolers to improve indoor air quality better than mechanical cooling which mostly recirculates warm, polluted, indoor air. During the evaporative process, water in the evaporative cooler unit changes from liquid to gas. This evaporative process requires energy, in the form of heat, which is extracted from the air, cooling it. Evaporative coolers are designed for use in your home or business. The evaporative coolers here range in diameter from 10in.–50in. and offer airflow in the range of 250 CFM–24,000 CFM. This lineup also offers both oscillating and non-oscillating evaporative coolers.

One of the more popular units in this selection is a 36in. unit that effectively cools up to 2100 sq. ft., so it’s an ideal solution for a warehouse space, barn, gymnasium or other large space. This 1/2 HP unit delivers 8000 CFM of cooling comfort, lowering air temperature by as much as 30°. This evaporative cooler includes a water level indicator to show how much water is left in the reservoir, with a red LED indicating the reservoir is empty. This 40-gallon unit can be filled either manually or with a garden hose. An evaporative cooler like this is a great alternative to air conditioning, as it works anywhere standard air conditioning is ineffective or cost prohibitive.
