Gebwell shunt group

Factory-made unit to be used as a control group in secondary circuit.

The shunt group enables accurate temperature control of the water coming from a high-temperature main line to a heating network with lower temperature. It can for example be used as a control circuit for a ventilation unit.

The Gebwell shunt group saves installation time because there is no need to build a shunt group on-site using individual components.

The fully encased and insulated shunt group is attached to the wall with brackets supplied with the unit.

The Gebwell shunt group is available in three different models: H, L and U, according to primary circuit connection direction (see gallery below).

The shunt group is available equipped with a 2- or 3-way valve, different pipe sizes, different circulation pumps, different actuators, and with a 0–10 V or 230 V control message system.
