Termix BVX FI RO T/E
Indirect substation for single-family houses or apartments
Application
The Termix BVX FI 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, pressure gauge, 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 FI RO T/E can be supplied with a thermostatic circulation
valve or a built-in non-return valve.
Option delivered loose with the unit.
Construction
All pipes are made of stainless steel.
The connections are made with nuts
and gaskets. The Termix BVX FI RO T/E
is completed by a white steel cover in
modern design with door. The 105 ltr.
tank can replace the older 150 ltr. tank
thanks to the unit being fully insulated.
This will save space as well. Non-return
valve and safety valve for the cold water
supply is delivered loose with the unit.
