Commercial evaporative coolers, also known as commercial swamp coolers, provide powerful cooling in large indoor areas, manufacturing plants, and outdoor spaces. A cost-effective solution for portable cooling in dry climates, an industrial swamp cooler uses the natural process of water evaporation to reduce heat and lower humidity. These heavy-duty portable coolers work by passing warm, stuffy air through a damp evaporative cooling pad that absorbs heat and transforming the hot air into a refreshing cool breeze. Many of our commercial swamp cooler models connect to a standard garden hose and feature remarkable CFM capacities – some units pull in as much as 9,600 cubic feet of air per minute. More energy-efficient and eco-friendly than traditional air conditioners and more powerful than typical outdoor fans, industrial evaporative coolers effectively cool athletic events, warehouses, construction sites, pool or patio areas, and more.
