Meet the all-new DSP MOD@ substation
DSP stands for ‘Danfoss Substation Prefabricated’, highlighting the fact that you get a substation that is easy to install and that complies with 90% of the typical district heating network technical connection requirements. MOD@ stands for ‘modular and digital’, meaning you get a substation that’s flexible, easy to configure and works seamlessly with our digital district heating network product portfolio.
You can use DSP MOD@ substations:
- in indirect heating applications with single or double heat exchanger applications.
- for heating multi-family homes and commercial and industrial buildings.
- together with a centralized domestic hot water (DHW) system or heat interface unit that you can connect to the substation’s secondary side.

DSP MOD@ is a substation that is modular, easy to specify and that complies with the typical technical connection requirements of a district heating network.

With DSP MOD@ you get a high-quality station that delivers high system performance and end-user comfort by energy efficiency, safe and reliable operation.

With DSP MOD@ you save time when planning the design, installation, during delivery, handling and when installing and servicing the station.
Features and benefits
A substation built to optimize heating system performance:
-
The ECL Comfort 310 controller featuring weather compensation, data logging and alarm monitoring.
-
Micro Plate™ heat exchangers improve heat transfer efficiency, performance, and flow distribution, while reducing pressure loss by 35%. The heat exchanger’s unique, patented dimple design enhances heat transfer performance by up to 10% when compared to the traditional fishbone design.
-
AHRI-certified gasketed heat exchangers improve low load control and minimize energy consumption.
-
The new Virtus iSET intelligent pressure independent control valves (PICV) provide stable control and reduce return temperature.
-
Works seamlessly with Danfoss Leanheat® Monitoring and Titan™ to further optimize energy efficiency and lower the return temperature in district heating networks.
