The range of plates produced for the -Plate&Shell- product family currently comprises 9 sizes with diameters ranging from 190 to 1358mm. Plates can be produced in a wide range of materials. After pressing and cutting, the plates are welded together to form a fully welded platepack. Nozzles are added which carry flow in and out of the platepack (the 'Plate side' flowpath).
The fully welded platepack is assembled into an outer shell which creates a second flowpath ( the 'Shell side'). The different types of shell arrangements and the normal flow patterns are shown below.
PSHE requires only 25% of the surface compared to Shell & Tube heat exchangers, however, it is possible to construct PSHE exchangers with over 2000 m²of heat transfer area. The compact size of the PSHE minimizes installation, operating and maintenance costs, which again saves energy and the environment.
Robust and gasket-free construction
The gasket-free construction is durable enough for the harshest conditions and prevents maintenance issues and no leakages in very high / low pressures and temperatures.
High thermal efficiency
The construction of the PSHE creates high turbulence between the plates, which enables very high thermal efficiency. This allows user to take full advantage of a compact heat transfer solution in extremes of temperature and pressure, which was not possible in traditional compact heat exchangers.
