The heat exchanger is divided into tubular heat exchanger, spiral plate heat exchanger. And the commonly used tubular heat exchanger comprises condenser, Pre-heater, Re-boiler, Evaporator, drying machine. The spiral plate heat exchanger comprises non-dismountable and dismountable exchanger.

Types: plate heat exchanger, spiral plate heat exchanger, threaded locking-ring heat exchanger and shell and tube heat exchangers.

Shell and tube heat exchanger contains: fixed tube-sheet heat exchanger, U-tube heat exchanger and floating head type heat exchanger and so on.

Materials: not only stainless steel, but also carbon steel, low-alloy steel, and non-ferrous metals: titanium, nickel, copper, aluminum, molybdenum, zinc, cobalt etc and their alloy materials.

Pressure: low-pressure, medium-pressure and high-pressure.

Temperature: low-temperature heat exchanger, medium-temperature heat exchanger but also high-temperature heat exchanger.

Medium: not only non-flammable, non-toxic and non-corrosive medium but also flammable, toxic, corrosive medium and highly flammable, highly toxic, highly corrosive medium.

Concrete products: coolers, condensers, heater, pre-heater, vaporizers, re-boilers, evaporators, dryers, steam wok, preheat pan, solvent pre-heater, steamer, steam offline, electric steam generator, gas furnace water jacket and so on.
