Heat Exchanger 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 or the fluids are directly contacted.

Fans are used to generate the air to transfer the heat, hence fans are the essential part of the heat exchangers. It is very important to select a suitable fan according to the application of the heat exchanger and PARAG has developed the range of fans particularly for heat exchanger application.
