The VX is a substation featuring high performance and simple operation. The VX is especially suitable for two-pipe systems and systems with floor heating.

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.

The heating side consists of a stainless steel plate heat exchanger, manometer, thermometers, expansion vessel and circulation pump and the heating temperature is controlled by an electronic temperature controller with an outdoor temperature sensor. Depending on substation’s application, 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.
