PSHE consists of a circular plate group and shell. The plate group, enclosed in the pressure vessel, is the core of the heat exchanger. As heat transfer components, plates determine the heat transfer performance of the heat exchanger. Shell is the essential for the temperature, pressure capacity and safe and reliable operation.

Based on specific operating parameters, media flow paths can be set properly, which ensures the reasonable match of heat transfer efficiency and the resistance loss, and at the same time minimizes equipment investment and operating costs.
