Evaporative Coolers and Accessories

Evaporative coolers use the cooling effect produced when water turns into vapor to cool larger areas where a typical air conditioning unit is impractical and cost prohibitive. These swamp coolers cool warehouses, factories, loading docks, and large indoor areas as large as 10,000 sq. ft. Find belt-driven, direct and pneumatic cooler options. Swamp cooler accessories include purge pumps, automatic shut offs, recirculating pumps, water tanks, protective covers, replacement cooler pads, and more. We even have maintenance items such as cooler cleaner, water conditioner tablets, and mineral treatments to soften water. Shop Grainger today for the swamp coolers and accessories you need.
