Danfoss Heating - DSE Flex - Bespoke Solutions

DSE Flex - Indirect Connections - Heat Exchanger - LTHW - Low Temperature Hot Water


District heating and cooling transfer stations provide the link between energy suppliers and customers’ systems. They incorporate the necessary equipment to tailor the supplied heat to the needs of the object premises as specified in the heating supply contract.

In this they need to comply with all applicable standards and with the supplier’s technical connection conditions. Indirect connections (in which district heating and in-house systems are hydraulically isolated) incorporate components to separate the systems (heat exchanger), to limit the flow volume to that specified in the contract, regulate the secondary supply temperature and measure the energy consumption.

The system described here is a standard type and can be adapted to your specific project requirements.


Low Temperature Hot Water (LTHW) drawn from the pipeline of the local or district heating supply company is fed into the station at an appropriate temperature and pressure, which may be higher in winter than in summer. In the primary supply line this LTHW will flow through a shut-off valve and a dirt trap/ strainer.

The supply and return lines will incorporate a thermometer and a manometer to register the temperature and pressure. There will also be regulatory equipment in the return lines of the primary as specified by the circuit design. On secondary side 3 types of pump modules and different options can be connected.


The DSE Flex is designed to your needs in advance, assembled in factory conditions and then delivered, pre-assembled and ready to connect to the system. The controls are pre-wired for quick and simple installation to the network, or left out of the station to enable building management contractors to control it externally.
