Plate & Shell Heat Exchanger Concept

Below shows the basic concept of a single plate pack in a PSHE. The plates are arrange as shown below with 1 plate turned 180 to one side and welded to the first plate which the plate pack is a multiple of welded plates assembled.

Shell Arrangements

Below shows the basic shell arrangement of a fully welded PSHE:

  1. End Plate
  2. Plate Pack
  3. Flow Direction
  4. Mantel/Shell

Other Features

Flow Directors

Different plate pack orientation to direct the flow of the fluid for different applications

  1. General Applicaiton
  2. Gas Application
  3. Flooded Evaporators
  4. Condensers
  5. Combined Evaporators


The PSHE is also capable of running multi-pass application by using stoppers in between shell & plate pack or in between plates.
