General description and
application

Maximum operating
parameters

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 specied 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 ow volume to that specied 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 dierent types of pump modules and dif­ferent options can be connected on the secondary.
Thus, this system is especially suitable for District
Heating applications.
