GM PF mixing unit for heating in floor/ceiling/wall systems, even on large surface. The supply water temperature is controlled by a set-point thermostatic mixing valve. The module also contains an electronic circulation pump with variable flow-rate and head, ensuring high efficiency and very low power consumption. It also includes two shut-off valves provided with flow and return thermometers, PPE insulating shell and check valve to avoid bacterial diffusion. The mixing unit can be mounted in series on wall manifolds. • Pump centre distance: 125 mm • Max. temperature: 95 °C • Max. working pressure: 8 bar • Electric supply: 230V- 50 Hz • Size (wxhxd): 250x400x170 mm • Weight (DN 25): 5.3 Kg • Weight (DN 32): 5.6 Kg
