Thermoreflux

The Thermoreflux X60 pump group is a ready-to-assemble, compact return flow increase / charging valve unit
Maintaining the boiler and return temperature for all common boiler sizes from 5kW to 50kW nominal output. Thermally controlled with built-in three-way brass mixer.

A Grundfos UPM3 Hybrid 25/7 130mm high-efficiency pump is installed. In the upper area of ​​the pump group there are flat-sealing shut-off valves (1" IT) with built-in thermometers (0-160°C).

If the pump group is installed individually, a wall bracket can be screwed to the shut-off valves (not included in delivery). The well thought-out thermal insulation made of EPP ensures an optimal climate inside the insulation, so that
no heat build-up occurs.
