Air-cooled Fluid Cooler (ACFC) is an American Technology High Efficiency dry cooling system. ACFC works on principle of rejecting heat from hot fluid to ambient-air directly through heat transfer coils. This is in contrast to conventional method of cooling using shell & tube heat exchanger & wet cooling tower system.

The obvious advantage of ACFC is that it does not work require any water after its first charge. This is completely a closed circuit system. The hot fluid (water) from the source is made to pass through finned surface heat transfer coils & using the heat is rejected to ambient air passing through coils using axial fans.

The ACFC can be designed to reject heat from as small as 100 KVA DG Sets to as large as 300 MW power plants.
