Danfoss VX Solo II Fact sheet
MAKING MODERN LIVING POSSIBLE
VX Solo II
Substation for single-family, semi-detached and terraced houses as well as flats
District heating substation for indirect heating. With connection pipes for DHW cylinder. Designed for wall-mounting with pipes connection in top or bottom
Application
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.
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 pipe, as well as strainer, ball valves and pockets for pressure gauges.
As a standard the substation is supplied with fitting piece for mounting of heat meter in the DH return pipe.
Heating (HE)
The heating side consists of a stainless steel plate heat exchanger, manometer, thermometers, expansion vessel and circulation pump(s) and the heating temperature is controlled by an self-acting thermostatic valve or an electronic temperature controller with an outdoor temperature sensor, in combination with an actuator.
Dependingonsubstation’sapplication, different heat exchangers dimensioned for central or floor heating can be used. As an option the substation can be equipped with a thermostat with safety monitor.
Domestic hot water (DHW)
The substation can be supplied with connection pipes for DHW cylinder on the supply or return line.
Construction
All pipes are made of stainless steel. The connections are made by nuts and gaskets. The substation offers variable connection possibilities, as connection of pipes can be established both in the top or in the bottom of the substation. The VX Solo II can be delivered with white-lacquered steel cover, with door.
Variants
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.
Enclosed application sheet illustrates the available variants.
FeATURES AND BENEFITS
••Substation for single-family houses
••Indirect heating, - one or two heating circuits
••Selfacting or electronic control of heating (HE) temperature
••Connections for DHW cylinder on DH supply or return line
••Pipes connection in top or bottom of substation = Savings in installations costs
••Pipes and heat exchanger made of stainless steel, connections with EPDM gaskets.
••Minimized risk of lime scale and bacteria formation
••Electrical wiring from factory - Plug & Play
••Capacity: 20-30 kW HE / 15 kW FH
