VXi Solo HWP (A337)

The VXi Solo HWP (ECL 310/A237) is a fully insulated, indirect district heating/cooling compact station with one heating circuit and an additional connection for a domestic hot water storage tank in the primary circuit. It is suitable for systems with radiators and underfloor heating. The station is equipped with weather-compensated control.

District heating (DH)
On the primary side includes a fitting for heat meters in the district heating return line, sensor pockets for heat meters, a dirt trap, thermometers, a differential pressure regulator with flow limiter AVBP-F, a VS2 two-way valve, and ball valves.

Heating (HE)
On the secondary side consists of a stainless steel plate heat exchanger, a safety valve, an expansion vessel, a dirt trap, thermometers, a pressure gauge, a circulation pump, and ball valves. The radiator heating circuit is controlled by the primary-side VS2 two-way valve together with the AMV 150 actuator, and the temperature is regulated by an electronic controller (ECL 310/A237). Differently sized heat exchangers are used depending on the application. Type XB 06H-26 and type XB 06H-40 heat exchangers are used for radiators, and type XB 06L-24 for underfloor heating. A safety valve and an actuator with a safety function are available as options for underfloor heating.

Domestic hot water (DHW)
The VXi Solo HWP is supplied with a domestic hot water storage tank connection on the primary side. The storage tank temperature is optionally regulated by an automatic thermostatic control valve or the Danfoss ECL controller with an optionally available motorized control valve.
