Air Cooled Heat Exchangers


The Air-Cooled Heat Exchanger (ACHE) is a pressure vessel which cools a fluid within finned tubes by blowing ambient air over the tubes, with the help of fans. The biggest advantage associated with an ACHE is that it does not require any cooling water like the shell and tube heat exchanger. Hence it does not need to be near a cooling water source. It is a means of transferring energy to ambient air without any environmental concerns and high running costs. The applications include various industrial processes; however they are mostly used to cool gases of fluids when the desired outlet temperature is higher than the surrounding ambient air temperature.
