Selecting the right district heating substation makes commercial sense

No matter what kind of district heating or cooling substation you need, Danfoss will find a match in our comprehensive range of substations and heat transfer solutions.

Each building has its specific heat demands, every district heating company has its technical connection requirements and each resident have individual heating habits. These criteria influence on the selection of stations for heat distribution in buildings and villages as well as in small and large district heating networks.

The size of a station is determined by the heat demand of the apartment or the building which needs to be heated. Temperature and pressure of the primary power supply determine whether a station is operated directly or indirectly.

In addition, many district heating networks specify special technical connection conditions, which require special control components. And finally, the number and type of heating circuits as well as the form and function of the domestic hot water will influence the needed equipment.

Danfoss offers a complete program of substations and flat stations for ranges starting from 15 kW up to more than 4 MW, for direct or indirect operating mode with one or more heating circuits and primary or secondary side domestic hot water heating as flow, storage tank or anti-legionella system.

The stations can either be pre-defined or pre-ordered custom build solutions. Danfoss has a significant project track record in handling large and small heating and district heating projects, so contact us, and our highly qualified and experienced team will help you to find and dimension the right stations for your requirements.
