Product types shown: 13
VX Solo II
The VX Solo II is a substation featuring high performance and simple operation. The VX Solo II is especially suitable for two-pipe systems and systems with floor heating. VX Solo II is available in various variants. The circuit diagram and the technical data on the back page illustrates VX Solo II HWS with 1 heating circuit and secondary connection for DHW cylinder, however, variants with 2 heating circuits, mixing loop and primary connection for cylinder are also available
VXe Solo HWS HT
Applications
The VXe Solo HWS HT (ECL 310/A337) 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 HT 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/A337). VXe Solo HWS HT station can be connected either in high temperature or low temperature district heating networks.
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 side consists of a stainless steel plate heat exchanger and the VXe Solo HWS HT substation is available with heat exchanger type XB 06H-26, XB 06H-40 for radiator heating. The heating side also features safety valve, expansion vessel, strainer, thermometers, manometer, energy-efficient circulation pump and ball valves. The HE circuit is controlled by the district energy class pressure independent control valve AVQM together with the AMV actuator with or without safety function, the temperature by means of an electronic temperature controller (ECL 310/A337).
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 water
The VXe Solo HWS HT 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 HT with connection pipes for domestic hot water cylinder on the secondary side is delivered with a factory installed circulation pump.
