VAHTERUS – Heat exchangers

VAHTERUS – Heat exchangers

Established in 1990, Vahterus is a Finnish family business focused on sustainable heat exchanger solutions. The company is named after its home village in the Vakka-Suomi region of Western Finland. Vahterus was founded in an old sheep farm set in beautiful countryside, and after almost three decades of business and growth, we’re still proud to call the village our home.

Since the beginning, our mission has been to provide the best heat exchanger solutions for our customers. Without heat exchangers, industries and households would stop running. Heat exchanger efficiency is also fundamental in the ongoing energy transition.

Our heat exchangers are built for the next generation: they save energy, are compact in size, always custom-made, and because of their fully welded structure, they’re durable enough for even the most demanding conditions.

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.

PSHE Construction

The principle of a heat exchanger is to transfer heat from the primary to the secondary side through a heat-transfer plate that separates the flows. Vahterus heat exchangers are used for heating, cooling, condensing, evaporating and the recovery of process heat. They are composed of a fully welded pack of circular heat-transfer plates installed in a cylindrical steel shell – hence the term Plate & Shell.

Fully Welded Plate Heat Exchanger (PSHE)

Vahterus PSHE is a fully welded plate heat exchanger. This means that the heat-transfer plates are welded together with no need for an external gasket. Gasketed plate heat exchangers are suitable for many applications, but are limited in terms of temperature and pressure, coupled with the fact that there is always a risk of gasket failures and/or permeation. The same risks apply for semi-welded plate heat exchangers. With Vahterus PSHE, the risk of gasket failure is eliminated.
