VXe Solo HWS (A347)

Application
The VXe Solo HWS (ECL 310/A347) is a fully insulated substation for indirect heating with one heating circuit and secondary connection for DHW cylinder featuring high performance and simple operation. VXe Solo HWS is especially suitable for two-pipe systems such as systems with radiator or floor heating. Designed for wall-mounting with pipes connection in bottom. The heating circuit and the cylinder temperature is controlled by electronic temperature controller Danfoss ECL 310/A347.
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 line, as well as strainer, thermometer and ball valves. The heating temperature and the inlet temperature for the DHW cylinder is controlled by an electronic ECL 310/A337 controller with weather compensation.

Heating (HE)
The heating circuit on the secondary side consists of a stainless steel plate heat exchanger, circulation pump, dirt trap, expansion tank, thermometer, pressure gauge, non-return valve, vent valve and sensors, safety valve and ball valves and is controlled by a three-way valve. The VXe Solo HWS is available with two heat exchangers: - XB06H-1 26 and XB06H-1 40, depending on heat demand. Temperature in HE circuit is controlled by Danfoss electronic controller ECL310/A347.

Mounting of heat meter
The substation is equipped with ¾” fitting pieces in the DH return flow for fitting of a heat meter.Domestic hot waterThe VXe Solo HWS is supplied with connection pipes for domestic hot water cylinder on the secondary side, and the temperature in the cylinder is controlled by the Danfoss ECL controller in combination with a control valve and actuator.VXe Solo HWS with connection pipes for domestic hot water cylinder on the secondary side is delivered with a factory installed circulation pump.

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 distance, it is possible to establish a nice piping. The removable cover plate in the front allows easy access to the specially designed chamber, where the most frequently used components such as ECL310 are located. The easy access chamber enables faster commissioning and maintenance without removing the whole cover of the substation.
