1. Heat exchanger in chemical, petroleum, power, food and many other industrial production occupies an important position, its heat exchanger in chemical production can be used as heater, cooler, condenser, evaporator and reboiler, etc., widely used.

2. Heater Heater is to heat the fluid to the necessary temperature, but there is no phase change in the heating fluid.

3. Preheater The preheater pre-heats the fluid to provide standard process parameters for the process operation.

4. Superheater Superheater is used to heat a fluid (process gas or steam) to a superheated state.

5. Evaporator evaporator is used to heat the fluid, to reach a temperature above the boiling point, so that the fluid evaporates, generally there is a phase change.

6. Can be divided into: floating head heat exchanger, fixed tube-plate heat exchanger, U-shaped tube-plate heat exchanger, plate heat exchanger, etc.
