What is the Vahterus Plate & Shell Heat Exchanger?

Vahterus’ unique Plate & Shell Heat Exchanger (PSHE) is at the forefront of heat-exchanger technology. The core is a fully welded plate pack enclosed in a strong shell structure, which eliminates the need for gaskets. 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 is compact and low weight, and since it has no gaskets, it can withstand higher pressure and temperatures than Plate & Frame heat exchangers. The structural properties of Vahterus PSHE also make it durable, easy to maintain and energy efficient.
