The Thermoreflux X pump group is a ready-to-install, compact return flow increaser/loading valve unit for maintaining the boiler and return flow temperature for all common boiler sizes from 5 kW to 80 kW nominal output. Electronically controlled with built-in three-way mixer made of brass. An Elodrive 20-80°C electronically controlled servomotor is installed. A Wilo Para 25/6 high-efficiency pump is also installed. In the upper area of the pump group there are flat-sealing shut-off valves (1" IG) with built-in thermometers (0-160°C).
It is a ready-to-install group that regulates itself using the control sensor.
