Danfoss VXi Solo H Fact sheet

MAKING MODERN LIVING POSSIBLE

VXi Solo H

Fully insulated district heating substation for single-family, semidetached and terraced houses as well as flats.

Substation for indirect heating with one heating circut. Designed for wall-mounting with pipes connection in top or bottom. Electronic temperature controller ECL 310/A230

Application

The VXi Solo H (ECL 310/A230) is a fully insulated substation featuring high performance and simple operation. VXi Solo H is especially suitable for two-pipe systems and systems with floor heating. The heating circuit is controlled by electronic temperature controller Danfoss ECL 310/A230.

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, thermometer and ball valves.

Heating (HE)

The heating side consists of a stainless steel plate heat exchanger, safety valve, expansion vessel, strainer, thermometers, manometer, circulatiopump and ball valves.

The radiator circuit is controlled by the primary side flow controller with integrated control valve AHQM together with the actuator AMV 150, the temperature by means of an electronic temperature controller (ECL 310/ A230) .

Dependingonsubstation’sapplication, different heat exchangers dimensioned for central or floor heating can be used.

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 white removable center part in the front insulation allows easy access to components for regulation and maintenance purposes.
