About Vahterus

Vahterus is a Finnish family business founded in 1990. We are the inventor, pioneer and market leader in Plate & Shell Heat Exchanger technology. 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.

We aim to maintain our position as forerunners in our field through continuous product development, automated production technology and strong application know-how. A significant part of our research and development is done together with our customers, finding solutions to each unique requirement. Several global patents and awards granted for our innovative design and environmentally friendly products are a token of the success of our work. With headquarters and manufacturing facilities in Finland and subsidiaries in the UK, Germany, China and the US, we currently employ more than 350 people globally.

Vahterus has brought many innovations to the refrigeration industry and remains active in developing new solutions for the future. Our focus is on applications that use natural refrigerants, where fully welded plate & shell heat exchangers are the perfect fit. We work closely with the world’s leading chiller manufacturers to develop customised products and entire product ranges. As heat recovery is becoming more and more important in the fight against global warming, we have developed new technologies for the growing market of heat pumps.

Vahterus Plate & Shell Heat Exchangers have a fully welded construction and low refrigerant charge, which guarantees maximum safety. Their compact design saves space and because there are no gaskets, units are low maintenance and easy to clean.
