Semi-welded plate heat exchanger consists of a series of 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.
