IBO SGB safety group is a device designed for installing a diaphragm expansion vessel and for monitoring and protecting heating systems against excessive pressure increases. The safety group is equipped with a pressure gauge, an automatic air vent, and a safety valve. The body of the safety group is made of steel and has a mounting rail that must be attached to the wall using wall plugs and screws. The safety group should be selected so that the valve opening pressure is lower than the maximum permissible boiler pressure.
Technical data:
- Max. operating pressure: 6 bar
- Max. operating temperature: 90°C
- Max. glycol concentration: 50%
- Pressure gauge range: 0–10 bar
- Max. diaphragm vessel diameter: 340 mm
