The Original Plate & Shell Heat Exchanger

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.

The benefits of Plate & Shell Heat Exchangers

Our Plate & Shell Heat Exchanger has numerous benefits 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 our Plate & Shell Heat Exchangers also make them durable, easy to maintain and energy-efficient.

Plate & Frame Heat Exchangers

+ compact
+ low fouling

+ high temperature
+ no gasket
- large size and weight
- high fouling

Plate & Shell Heat Exchangers

+ high pressure (200bar)
+ high temperature (-196°C~+600°C)
+ no gasket
+ compact (~1/5 S&T)
+ low weight (~1/10 S&T)
+ low fouling
+ close approach temps
+ big temperature difference
+ batch process
