Semi-welded Plate Heat Exchanger
The Semi-weld Plate heat exchanger plates are welded by laser. the laser welding means that metal is melted by a laser beam from a high power laser. The charge is protected by irert gas Additional welding material is not required.
The semi-welded plate heat exchanger consists of two types of plates: fully welded plates and gasketed plates. The fully welded plates are used to form the channels for the high-pressure and high-temperature fluids, while the gasketed plates are used to separate the fluids and form the channels for the lower-pressure fluids. This design provides the advantages of both fully welded and gasketed plate heat exchangers, while eliminating their disadvantages.
