Air Cooled Heat Exchangers, or Air Fin Coolers, are used in any application where large quantities of heat need to be transferred. This includes chemical and petrochemical industries, power stations, waste to energy facilities as well as steelworks.

Using air rather than water for cooling is a cost efficient alternative, which also controls the thermal overload of rivers and lakes. Direct dry cooling offers substantial advantages since air is generally non-corrosive and of unlimited supply.
