G2 TECH Dual Ring Main
Dual domestic hot water ring main pump-sets
The G2 Tech dual domestic hot water ring main pump-set is a packaged system comprising of two Grundfos pumps, plumbed in parallel with the operation of the two pumps electronically controlled. Pump failure will initiate operation of the second (stand-by) pump automatically and the control cabinet will alert the building of the pump fault. This will be done via the BMS (when fitted) and using a visual strobe located on top of the control cabinet. The faulty pump can then be replaced without any interruption to the hot water supply to the facility.
