Plate Heat Exchangers

FSK is specialized in jointly designing and manufacturing different types of compact heat exchangers for heating, cooling, condensing and evaporating solutions including:

Standard plate heat exchanger
The plate pack is assembled between a fix frame plate and a movable pressure plate and compressed by tightening bolts. The plates are fitted with a gasket which seals the interplate channel and directs the fluids into alternate channels.

Semi-welded plate heat exchanger
Semi-Welded exchangers are two plates laser welded together to form a cassette. The advantage of this construction is that, one side of the cassette is a sealed welded channel, whilst the other is a traditional gasketted plate channel making assembly and cleaning of this site easier.

Fully-welded plate heat exchanger
The small plate gaps in the all-welded heat exchangers allow them to operate with very close temperature approaches compared to traditional shell and tube heat exchangers. The no gasket solution in the all-welded heat exchangers makes them suitable for many difficult applications.

Brazed plate heat exchanger
Brazed plate heat exchanger consists of a number of thin acid-resistant precision stamped stainless steel plates with copper brazed gaskets. The plate packs are brazed with two end plates and connections. Vacuum brazing at extremely high temperatures provides a permanently sealed heat exchanger. The final result is a strong and compact plate heat exchanger with extremely high heat transfer capability.

Shell and plate heat exchanger
A fully welded plate pack, laser/TIG welded together and mounted inside a traditional cylindrical shell. With a high thermal efficiency and lower purchase cost, the plate and shell heat exchanger combines the benefits of a traditional shell & tube type heat exchanger but with the high efficiency provided for in a plate type exchanger.

Spiral heat exchanger
Spiral Heat Exchangers are circular heat exchangers with two spiral channels, each in one closed chamber. The flow of the two products are countercurrent which makes it possible to have a close temperature approach between the two medias being treated in the heat exchanger.
