Air cooler

The function of an air cooler is similar to that of an evaporator. What makes it different is the type of cooling medium it uses. An air cooler is a heat exchanger used to cool and/or dehumidify the air.

Brine (water with glycol) is typically used as a coolant in air coolers or some other secondary coolant can be used. An air cooler can, for example, be copper or steel pipe onto which aluminum fins are fitted. The cooling medium flowing through the heat exchanger cools the aluminum fins, where heat is exchanged between the cooling medium and the air. The air that is to be cooled/dehumidified is forced over the aluminum fins by a fan.

Grundfos supplies a broad range of circulator pumps as air cooler pumps for air conditioning in buildings, industrial air-cooling processes and other applications.
