The construction of Vahterus PSHE is ideal for condensing applications. Key benefits include high thermal efficiency, small/reduced refrigerant charge, and low pressure drop. PSHE are suitable for all refrigerants over a wide temperature and capacity range.
The Plate & Shell Heat Exchanger (PSHE) is the first of a new generation of heat exchangers developed by Vahterus. At the heart of the PSHE is a fully welded pack of circular plates housed within an outer pressure vessel. The PSHE combines the best features of PHE and shell & tube exchangers offering a durable, compact and gasket free solution with high heat transfer, high pressure and high temperature capability. PSHE can either be described as a fully welded, high integrity plate heat exchanger, with no gaskets; or a generic alternative to Shell & Tube, approx. 25% of the footprint, displaying both space and weight benefits.
Vahterus PSHE can be used in many applications, in each instance offering space and weight benefits over traditional shell & tube exchangers. The key benefits are:
No Gaskets or Brazing
High Integrity / Total Containment
Strong and Safe Construction
Unique Protection and Resistance to Thermal and Pressure Cycling
