Danfoss VXe Solo H OP HT Fully Insulated Substation
Application
The VXe Solo H OP HT (ECL310/P330) is a fully insulated substation for indirect heat-ing with one heating circuit featuring high performance and simple operation. VXe Solo H OP HT is especially suitable for two-pipe systems such as systems with radiator heat-ing. Designed for wall-mounting with pipes connection in bottom. The heating circuit is controlled by electronic temperature con-troller Danfoss ECL 310/P330. The VXe Solo H HT can be connected in either high or low temperature district heating networks (Tmax = 130°C).
District heating (DH)
The substation is prefabricated with inter-connecting components such as fitting piece and sensor pockets for insertion of a heat meter installed in the DH return line, as well as strainers, thermometers and ball valves. The heating temperature is controlled by an electronic ECL 310/P330 controller with weather compensation, which enables fur-ther energy savings.
Heating (HE)
The heating side consists of a stainless steel plate heat exchanger and the
VXe Solo H OP HT substation is available with heat exchang-er types XB 06H-26
and XB 06H-40 for radi-ator heating. The heating side also features safety
valve, connection for an expansion vessel, strainer, thermometers, manometer
and ball valves. The HE circuit is controlled by the district energy class
pressure independent control valve AVQM together with the AMV actu-ator with
or without safety function, – the temperature by means of an electronic tem-
perature controller (ECL 310/P330).
Mounting of heat meter
The substation is equipped with 3/4” fitting pieces in the DH return line for
fitting of a heat meter. Calculator of the heat meter can be mounted into a
special chamber, that is designed for easy reading.
Design
The design emphasizes the user-friendly placement of all components. The VXe
Solo H OP HT is supplied with an elegant insulation cover and a removable
cover plate in the front insulation.
Service and maintenance
The substation is very service-friendly and easy to install. It is mounted on
the wall and as all pipes are placed in pipe bracket dis-tance, it is possible
to establish a nice pip-ing.
The removable cover plate in the front al-lows easy access to the specially
designed chamber, where the most frequently used components such as ECL 310
are located. The easy access chamber enables faster commissioning and
maintenance without removing the whole cover of the substation.
