Termix BV

Instantaneous water heater for large apartment houses, sports arenas and schools

Application

The Termix BV substation is an
instantaneous water heater fea­turing superb heat extraction
and high performance. The sub­station is delivered with ther­mostatic or automatic controls.
The Termix BV is suitable for large
apartment houses, sports arenas and
schools, where large amounts of hot
water are needed. The hot water sys­tems are available in 7 different sizes
with an output from 77-265 kW. The
Termix BV unit is supplied with PU in­sulated heat exchangers.

Domestic hot water (DHW)

The domestic hot water is prepared
in a plate heat exchanger and the
temperature is regulated with ther­mostatic or automatic controls.
The thermostatic solution is regu­lated with self-acting thermostatic
control valves. The substations with
high output are controlled with two
valves connected in cascade in order

to control both small and
large demands for hot wa­ter in an efficient manner.
The Termix BV can also be mounted
with automatic controls. There is no
additional pressure loss on the sec­ondary side of the heat exchanger
with a thermostatic or automatic
control valve. Therefore this type of
regulation can be used by low pres­sure in the cold water mains.

Domestic hot water circulation

The Termix BV substation is supplied
with connections for DHW circula­tion including circulation pump and
a non-return valve as a standard.

Options

The substation can be supplied with
a safety valve and a thermostatic cir­culation valve.

Construction

All pipes are made of stainless
steel. The connections are made
by nuts and gaskets. The Termix BV
substation can be delivered with a
white-lacquered steel cover in mod­ern design.
