The safety group is designed for autonomous hot water heating and DHW systems with a capacity
up to 44 kW and pressure up to 10 bar. It provides the following functions:
-Protection against overpressure in the system;
-Diverting air and gases from the system;
-Indication of pressure in the system at the manometer level;
-The group has an additional threaded outlet for connecting an expansion tank;
Safety group is equipped with an automatic float air vent: a safety valve and manometer. The safety group has a flange for cantilever mounting to the wall. The dimensions of the safety group allow hanging an expansion tank up to 24 litres directly to it. Included: automatic air vent, safety valve and pressure gauge.
