Industrial Air Coolers work by drawing in hot air from the outside and passing it through a wet cooling pad. The water in the pad evaporates, which cools the air. The cool air is then blown back out into the room or space. This process is called evaporative cooling, and it can significantly reduce the temperature and increase the humidity in the surrounding area. Industrial Air Coolers are effective in dry climates and can provide an energy-efficient alternative to traditional air conditioning systems.
