Termix BVX RO T/E

Indirect substation for single-family houses or apartments

Application

The Termix BVX RO T/E substation is
a complete solution for hot water and
space heating with optimal safety, ef­ficient energy transfer, servicefriend­ly construction and a compact de­sign. The substation is used if a heat
exchanger is required or on a con­version to district heating where the
existing equipment is unsuitable for
direct connection.

District heating (DH)

The substation is prefabricated with
a differential pressure controller, fitting
piece and sensor pockets for insertion
of a heat meter as well as strainers and
ball valves.

Heating (HE)

The heating circuit consists of a plate
heat exchanger, safety valves, ma­nometer, thermometers, ball valves,
drain valve, air valves, expansion ves­sel and circulation pump. The tem­perature of the heating is controlled
by an electronic controller with an
outdoor temperature sensor.

Domestic hot water (DHW)

The domestic hot water circuit consists
of a hot water tank with coil and selfact­ing thermostatic control valve. The DHW
tank and coil are enamelled and the tank
contains a magnesium anode.

Options

The Termix BVX RO can be supplied
with a thermostatic circulation valve
or a built-in non-return valve and
safety valve mounted in the cold wa­ter supply. Both options delivered
loose with the unit.

Construction

All pipes are made of stainless steel. The
connections are made with nuts and
gaskets. The Termix BVX RO T/E is com­pleted by a white steel cover in modern
design with door and including external
thermometers.
