District Energy

Valves for district heating and cooling

We have great ambitions in the district energy market and offer a combination of high-quality products, extensive application knowledge and innovative, digital add-on solutions, giving our customers insight into, and control over, their network.

We have been active in the district energy sector since 1991 as a supplier of dynamic valves for district heating units, and we have continuously developed our district energy solutions in close collaboration with our customers.

We continue that development with our venture into IoT products for monitoring and remote control of valves. Going ahead, Frese will not only be a components manufacturer, but also a service provider to a district energy sector, which faces accelerating digitalisation, and where data can create value for both the industry and consumers.

The combination of our energy-saving dynamic valves and the potential of increased insight into networks makes us a natural partner in the green transition required to achieve significant reductions in CO2 emissions.

DE Valves

In 2020, we acquired the majority of DE Valves Glamsbjerg A/S, a manufacturer of fully welded steel ball valves for pre-insulation and underground installations in district heating networks in Denmark, as well as for district cooling projects in e.g. the Middle East.

With this partnership we can deliver valves for the full distribution network and offer optimisation of operations and energy both above and below ground – all the way to the individual private consumer's system.
