Plate heat exchangers are used extensively in many established industries as they are designed to optimise heat transfer.
The carefully designed corrugated surface of the plates provides a large heat transfer area while occupying a relatively smaller space. Plate heat exchangers are compact and flexible. The flexibility in plate arrangement ensures maximum turbulence and high heat transfer efficiency. Plate heat exchangers are used in general heating and cooling duties in Marine, Pharmaceuticals, Food, Medical, Process, Petro-chemical and general industries.
The plate heat exchanger consist of a series of thin corrugated plated that are assembled between a fixed frame plate and a movable pressure plate and compressed by tightening bolts. The number of plates is determined by the cooling surface required, the flow rate, physical properties of the fluids and their pressure drop. Connections are located in the frame plate or, in some applications, in the frame the pressure plates.
