Air Cooled Heat Exchangers is a device built for efficient heat transfer from one fluid to another, whether the fluids are separated by a solid wall so that they never mix, nor the fluids are in direct contact. Air cooled heat exchanger fans & Air cooled condenser fans are used to generate the air that transfers the heat, hence fans are an essential part of heat exchangers. It is very important to select a suitable fan according to the application of the heat exchanger and ‘Parag’ has developed a range of ACC fans particularly for heat exchanger application.
