Danfoss DH Standard Welded Stations

Type DSP 1 MAXI CEE

General description and application

District heating transfer stations provide the link between district heating 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 in which one of different types of pump modules and different options can be connected on the secondary. Thus, this system is especially suitable for District Heating applications.

Function	Hot water 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 hot water will flow
	through a shut-off valve and a dirt trap / strainer.
	The supply and return lines will incorporate a ther-
	mometer and a manometer to register the tem-
	perature and pressure.

There will also be regulatory equipment in the return lines of the primary as specified by the circuit design.

The cooled heating water then flows back to the local or district heating supply company via the primary return pipe.

On secondary side different types of pump modules and different options can be connected.
