Plate & Shell Heat Exchangerr

Our unique Plate & Shell Heat Exchanger (PSHE) is at the forefront of heat exchanger technology. The core of this heat exchanger is a fully welded plate pack enclosed in a strong shell structure, which eliminates the need for a gasket. Due to its advanced construction, Vahterus PSHE combines the best features of plate & frame and shell & tube heat exchangers.


  • Our PSHE has numerous advantages over traditional heat exchangers. It’s compact and light in weight, and since it has no gaskets, it can withstand higher pressure and temperatures than plate & frame heat exchangers. The structural properties of PSHEs also make them durable, easy to maintain and energy-efficient.
