The semi-welded plate heat exchanger is made of two plates along the sealing groove by laser welding to form a plate pair, the plate pair is sealed with a gasket, and sandwiched between the fixed compression plate and the movable compression plate in the form of superimposition of a heat exchanger. Boger semi-welded plate heat exchanger is welded by advanced laser welding technology with advantages of small welding deformation, small residual stress and high quality. It has the characteristics of high heat transfer efficiency, long service life and easy maintenance. It is suitable for cooling and chemical Treatment is a reasonable choice to replace shell-and-tube and fully welded plate heat exchangers, especially for evaporation and condensation of ammonia coolants, and chemical treatment processes for corrosive liquids. Mainly used in ammonia refrigeration, sulfuric acid, caustic soda, petrochemical, metallurgy, machinery, pharmaceutical, food and other industrial fields. Semi-welded plate heat exchangers are the prime choice for challenging applications with aggressive media or high pressures.
Jialin Machinery customizes each heat exchanger to your specifications and provides durable solutions to withstand extreme conditions and minimize the risk of using chemicals or refrigerants.

Jialin Machinery semi-welded heat exchangers are ideal for ammonia applications, while also easily handling most refrigerants. Primarily used in the air conditioning and refrigeration industries, they are often installed as evaporators, condensers or oil coolers, but their versatility means they can easily be configured for use in other industries and applications, such as chemical processing. With our solutions, you can safely operate with hazardous, aggressive media, high pressures or extreme temperatures, which are not suitable for conventional purely rubber-sealed heat exchangers.
