2.0 Functional description

District heating substation for indirect heating. Designed for
wall-mounting.
Application
The Termix VX Compact 20 substation is a complete solution
for space heating with optimal safety, efficient energy transfer,
service-friendly construction and a compact design. The substation
is applicable, if a heat exchanger is required or on a conversion to
district heating, where the existing equipment is unsuitable for
direct connection. The Termix VX Compact 20 is ideal, where a
high level of security against burst pipes and water damage in the
heating system is required.
District heating (DH)
The district heating circuit is prefabricated with a differential
pressure controller as well as thermometers and ball valves.
Heating (HE)
The heating circuit consists of a plate heat exchanger, safety valve,
mano-meter, thermometers, ball valves, drain valve, air valve, and
circulation pump. The heating temperature can be controlled
thermostatically or by an electronic controller with an outdoor
temperature sensor. Depending on the application, different heat
exchangers dimensioned for central or floor heating can be used.
Domestic hot water (DHW)
Termix VX Compact 20 is supplied with connection pipes for a DHW
tank on the supply line.
