Kühner Wärmetauscher -

since 1948 we stand for quality and competence


From the tradition of specialisation

The perfect heat exchanger for every application. Our company founder Wilhelm Kühner already set this standard and worked hand in hand with the customers to develop solutions for their specific requirements. And today - three generations later - the family-owned company Kühner still stands for high quality custom products which we produce in Germany. We utilise modern production technology and the accuracy of true craftsmanship, and build on the know-how and commitment of all employees. We keep evolving at all times in order to be able to offer our customers premium Kühner heat exchangers in the future as well.



Added value for our customers

Kühner heat exchangers support the production processes, and thereby the success of our customers. Not only our technical know-how but also a value system we live and breath every day flow into every Kühner product. Solidarity, quality, appreciation and clarity are the principles on which we base our thinking and actions.

Thus we cultivate a partnership relationship with our customer through individual consulting and well-founded engineering services. We take great care to adhere to our guidelines on safety, orderliness and cleanliness. This is because premium Kühner products can only be made in an optimal work environment. We communicate openly and clearly within the company and with our business partners. This allows us to express our appreciation and demonstrate that we are a reliable partner. We ensure a high level of quality and also tap into the full potential for continually optimising our processes and products.

We are delighted about every partner and customer whose values agree with ours.
