Vahterus

Vahterus is the inventor, pioneer and market leader in the field of Plate & Shell heat exchangers (PSHE). The core of this heat exchanger consists of a fully welded plate package enclosed in a strong round shell. Gaskets are therefore unnecessary. In this construction Vahterus PSHE combines the best features of Plate & Frame heat exchangers and Shell & Tube heat exchangers.

Knowledge and experience

Vahterus’ fully welded Plate & Shell heat exchangers are developed and built based on the extensive knowledge of heat transfer, lab tests and decades of practical experience in the market.

Compact heat transfer solutions

The Vahterus Plate & Shell heat exchangers are on average 60-70% smaller than a traditional Shell & Tube heat exchanger. That makes them extremely suitable for retrofitting of installations, e.g.

Vahterus and Kapp
Vahterus and Kapp are actually like brothers, raised together with the same ideas and a similar philosophy. Both carry out the mission to offer the best possible solution for every issue in the field of heat transfer. Because we grew up together, we have learned a lot from each other, and we still do to this day. Vahterus knows its products inside out and has an R&D strategy which actively involves partners and customers. Kapp knows the market better than anyone and knows the questions and answers. This allows us to respond to the constantly changing demands and needs of the industry.

To ensure that the heat exchanger does what it has to do, skilled personnel is undeniably important. Uncompromising work and strict testing procedures guarantee the quality of the product.

About Vahterus
Vahterus has conquered its place in the market. The Plate & Shell heat exchanger, invented by Vahterus is an integral part of the industry. Thanks in part to a worldwide network of representatives, the Finnish company has sold more than 55.000 heat exchangers in recent years.

 “…more than 25% of the staff has a background of technical engineer.”

The majority of the production facility is designed for customer-specific solutions. Vahterus has more than 300 employees for this, of whom more than a quarter have a background as a technical engineer. The high quality of Vahterus products is the result of continuous product development from design to production, automated production technology and broad process knowledge. A modern production site is essential for this. The Vahterus factory now covers a floor space of more than 13,000 m2.

Products
The core of the Vahterus heat exchanger consists of a fully welded plate package. The round plates are welded together, the openings between the plates acting as two separate channels for hot and cold media. The plate package is then installed in a cylindrical outer cover. This makes gaskets superfluous.

Just like the plate package, the cylindrical outer shell is fully welded. The plate package and the shell are not welded together, which means that they can expand and contract. The cold and warm media flow in opposite directions – one medium through the plate package and the other medium around it in the shell – and thus exchange heat.

Welded P&S

The fully welded plate and shell heat exchanger is a welded plate pack enclosed in a strong shell structure, to withstand high pressure, stress variation and thermal shocks.

Compact P&S

The compact plate and shell  heat exchanger is designed to save even more space than our standard model and this unit allows for an easier assembly at the customer’s site.

Openable P&S

The openable plate & shell heat exchanger offers increased flexibility, allowing the plate pack to be pulled out from the shell for inspection or mechanical cleaning.

We have at least the same requirements as you.

With the work that Kapp and Vahterus deliver, we demonstrate that we live up to our words. All our products meet the requirements and standards that are relevant to the industry our customers work in.
