Semi Welded Plate and Frame Heat Exchanger for Freon and Ammonia

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 - Industrial semi-welded line

Semi-welded plate heat exchangers are suitable for refrigeration, chemical processes and various kinds of industrial utility duties. The unique Alfa Laval RefTight sealing system guarantees a long lifetime sealing between the welded channels because the laser weld is on the outside of the ring gasket groove. Case Study Semi-welded plate evaporator and air purgerThe Danfoss Semi-Welded Plate and Frame Heat Exchanger SW 40A-90-TL is used as a flooded evaporator that cools 35% Propylene Glycol solution. The Follower (movable frame plate) has a nylon roller that provides easy access to the plate pack and reduces the likelihood of

Polaris Plate And Frame Heat Exchangers

Polaris Semi-Welded Plate Heat Exchangers handle the jobs conventional plate exchangers cant touch including ammonia refrigeration, CFCs, HCFCs, and aggressive process fluids. Resistant to stress and leakage, our semi-welded plate heat exchangers employ matched plate pairs (or cassettes) to isolate refrigerant or process fluids from the gasketing. Supply Semi Welded Plate Heat Exchanger Factory Quotes - Over 10 years' experience in the PHE field, we can provided technical service to help you save more cost.. Semi-welded plate heat exchanger is this kind of heat exchanger, whose plates are consist of two plates which is welded by laser along the seal groove, and the two plates are sealed by the gasekts which clamped on the fixed plate and active plate through superposition.

Semi-welded plate heat exchanger - Refrigeration ammonia

28 rows · The semi-welded plate heat exchangers from Danfoss is designed for ammonia systems and can be used for applications such as Condensers, flooded and pumped evaporators, Sub-coolers, Desuperheaters, Superheaters, Economizers and

• See all 27 rows on danfoss Ammonia permeation in semi- welded plate heat In a semi-welded plate heat exchanger (SWPHE) where one channel is filled with ammonia, there is a high concentration of ammonia on the inside and a negligible concentration on the outside. This will inevitably cause permeation to some degree. The permeation through metal is zero in all practical senses. But the ring gasket, made of a polymer-based material, will inevitably allow some ammonia
