About the
SONDEX® brand

Global presence, local proximity

Sondex A/S was founded in 1984 as a company aiming to provide customers with plate heat exchanger solutions that are tailored to their individual needs. The company, rooted in Denmark, greatly expanded during the following years and quickly became an enterprise spanning the entire globe.

With many sales and production subsidiaries across the world, Sondex became a leading manufacturer of plate heat exchangers while remaining close to our markets with local sales and service teams.


Complete in-house production

We do all our own tooling in-house and have our own hydraulic presses and gasket production facilities. The benefit of this specialization is closed loop production - it is easier to control and monitor the quality without relying on sub-suppliers.

We can execute product development tasks faster than most, as the tooling and engineering know-how is placed internally in Sondex.


Heat transfer specialists

We design our heat exchangers in close cooperation with our customers to perfectly match the thermal requirements of any duty. Throughout the years we have developed what has become the largest plate portfolio in the world. Having an option for every application and duty enables us to fine-tune each solution to the specific task at hand.

Optimized to minimize energy consumption and reduce of service and maintenance costs, our heat exchangers have a long lifetime and low purchase price.






Together, we offer twice the application
and customer focus

In July 2016, Danfoss acquired full ownership of Sondex. This step marks the coming together of two strong players creating an even more powerful and agile heat exchanger partner and provider.

From January 2018, Sondex will transition into a product brand and become part of Danfoss. The SONDEX® brand will continue as part of one of the most extensive product portfolios in the market.

With our world-leading product range and state-of-the-art technology, we can always offer you superior and customized solutions.

Going forward our combined sales organizations will operate side by side, and we will take pride in constantly providing you with the highest quality products and services. Your contact person will remain the same with the added advantage that you can now enjoy all the benefits of one-stop-shopping.
