Profile
Semi-welded plate heat exchanger consists of a series of cassettes-plate pairs, which formed by two plates laser welded together along the sealing groove. The aggressive medium flows inside the cassette, only in contact with a special designed ring gasket. Each cassette is fitted with a gasket. The other medium flows in the gasketed channels. Two media flow reversely in adjacent channels, between which heat transfer will take place. 

It is widely used in the evaporation and condensation of ammonia and freon refrigerant, industrial evaporation and condensation, water-cooled oil cooler, and general cooling and heating of high temperature, high pressure and strong corrosive media in one channel. Technical advantages Our semi-welded plate heat exchanger adopts the world's most advanced laser welding machine and modern laser beam welding process. Compared with other welding methods, laser beam welding process has the advantages of little deformation after welding, high welding quality, and small stress. It is particularly suitable for high pressure and corrosive conditions.

Main parameters
＊Pressure: Maximum design pressure is up to 30 bar.
＊Temperature: Maximum operating temperature is up to 200℃, minimum operating temperature is-40℃.
＊Corrosion: Resistant to most aggressive media.
