SHANTHI Aircooler in Coimbatore An industrial air cooler is a device designed to cool large spaces or industrial environments. Unlike traditional air conditioning units, industrial air coolers use evaporative cooling technology. They draw in warm air, pass it over water-saturated pads, and then expel the cooled air into the environment. These units are typically more energy-efficient and cost-effective than air conditioners, making them suitable for warehouses, factories, and other large areas. They work best in dry and hot climates, as the efficiency of evaporative cooling improves with low humidity.
