SHANTHI AIRCOOLER IN TIRUPUR An air cooler, also known as an evaporative cooler, is a device designed to cool air through the evaporation of water. It works by drawing warm air through water-saturated pads, where the water evaporates and cools the air. This cooled air is then circulated into the room. Air coolers are energy-efficient and environmentally friendly compared to traditional air conditioning units, as they use less electricity and don't rely on refrigerants. They're particularly effective in dry climates where the evaporation process can significantly lower the air temperature.
