SHANTHI INDUSTRIAL AIRCOOLER IN TIRUPUR An industrial air cooler is a device designed to cool large spaces, typically used in warehouses, factories, or other big facilities. It operates by blowing air over water-saturated pads, which cools the air through evaporation. Unlike traditional air conditioning systems, air coolers are generally more energy-efficient and cost-effective for large areas, but they work best in dry, hot climates. They can be installed as a fixed unit or used as portable coolers, depending on the needs of the space.
