Danfoss VXi Solo H Fact sheet
MAKING MODERN LIVING POSSIBLE
VXi Solo H
Fully insulated district heating substation for single-family, semidetached and terraced houses as well as flats.
Substation for indirect heating with one heating circut. Designed for
wall-mounting with pipes connection in top or bottom. Electronic
temperature controller ECL 310/A230
Application
The VXi Solo H (ECL 310/A230) is a
fully insulated substation featuring
high performance and simple operation. VXi Solo H is especially suitable
for two-pipe systems and systems
with floor heating. The heating circuit
is controlled by electronic temperature controller Danfoss ECL 310/A230.
District heating (DH)
The substation is prefabricated with
interconnecting components such as
fitting piece and sensor pockets for
insertion of a heat meter mounted in
the DH return pipe, as well as strainer,
thermometer and ball valves.
Heating (HE)
The heating side consists of a stainless steel plate heat exchanger, safety valve, expansion vessel, strainer,
thermometers, manometer, circulatiopump and ball valves.
The radiator circuit is controlled by the
primary side flow controller with integrated control valve AHQM together
with the actuator AMV 150, the temperature by means of an electronic
temperature controller (ECL 310/
A230) .
Depending on substation’s application,
different heat exchangers dimensioned for central or floor heating can be
used.
Construction
All pipes are made of stainless steel.
The connections are made by nuts and
gaskets. The substation offers variable
connection possibilities, as connection of pipes can be established both
in the top or in the bottom of the substation.
The white removable center part in
the front insulation allows easy access to components for regulation and
maintenance purposes.
