Dry Air Coolers

The dry air coolers are used at places where excess heat rejection to the atmosphere is required. Their function does not depend on evaporation method, which eliminates the need of water. In lieu of compressors or refrigerant, they use water/ethylene glycol or water/propylene glycol to transfer heat. The solution is circulated through the cooler via pipes, which absorbs heat from the surrounding. This is the time when heat exchange takes place and a series of condensing fans mounted on the unit perform its cooling.
