Air cooled heat exchangers (ACHE) use finned tube pressure vessels in which a fluid is circulated. Ambient air is forced over these finned tube bundles to dissipate heat. In comparison to cooling towers, air cooled heat exchangers offer a green solution. They do not require water or the associated water make-up due to drift and evaporation. Nor are there any chemical treatments required.

For the convenience of users, our reference models of air cooled heat exchangers are according to GB/T15386-94 and design according to API 661.
