Refrigerant Use Semi Welded Plate and Frame Heat Exchanger

Alfa Laval - Industrial semi-welded line

Alfa Laval Industrial Semi-Welded with unique sealing system. Alfa Laval Industrial semi-welded line handles most refrigerants and is particularly suitable for applications involving ammonia. Semi-welded heat exchangers are used in both organic and inorganic chemical processing when the chemicals involved limit the selection of gaskets that can be used or when the required design pressure makes fully gasketed plate-and-frame heat exchangers

Alfa Laval - Semi-welded

Industrial semi-welded GPHEs. Industrial semi-welded gasketed plate heat exchangers are used when gaskets are not suitable as one of the process media. Semi-welded GPHEs can also take a higher design pressure compared to fully gasketed plate-and-frame heat exchangers. In the Semi-welded heat exchanger the refrigerant flows in laser-welded, sealed plate channels, and in the opposite Ammonia permeation in semi- welded plate heat Semi-welded heat exchangers are the perfect choice for a wide range of refrigeration systems and offer benefits such as excellent heat transfer efficiency, easy capacity expansion and high resistance to fatigue. Ammonia is a common refrigerant and is used in many applications. In some cases operators notice a weak smell when they are very

Plate heat exchangers for refrigeration - Alfa Laval - PDF

Semi-welded plate heat exchanger The Alfa Laval semi-welded heat exchanger (SWPHE) alternates welded channels and traditional gasketed channels. The refrigerant flows in welded channels and the only gaskets in contact with the refrigerant are two circular porthole gaskets between the welded plate Plateflow - gasketed plate & frame heat exchanger SEMI Plate and Frame heat exchangers use a combination of chevron-style heat transfer plates sequenced between a frame plate and pressure plate. The heat transfer plates have holes at the four corners forming a header that distribute the respective flows to the opposite sides of each plate when the plates align. Semi-welded designs available in 2.5, 4, 6, 8 12 and 18 connection sizes.
