Semi welded plate heat exchanger is a kind of heat exchanger that uses two plates to weld into a pair of plates along the sealing groove by Laser beam welding, seals the pair of plates with sealing gasket, and clamps them in the form of superposition between the fixed clamping plate and the movable clamping plate.

THT Juyuan semi welded plate heat exchanger is welded by the advanced laser welding technology in the world with advantages of small welding deformation, low residual stress and high quality. It is characterized by high heat transfer efficiency, long service life and easy maintenance. It is suitable for cooling and chemical treatment. It is a reasonable alternative to shell and tube type and all welded plate heat exchangers, especially suitable for evaporation and condensation of ammonia coolant, And chemical treatment processes for corrosive liquids. Mainly used in industries such as ammonia refrigeration, sulfuric acid, caustic soda, petrochemicals, metallurgy, machinery, pharmaceuticals, food, etc.
