Application
- Protecting central heating systems with boilers and heat pumps where safe operating pressure must be maintained and a diaphragm expansion vessel must be connected.
- Use in small and medium-sized water-based boiler rooms where constant pressure monitoring with a pressure gauge and automatic system venting are required.
- Heating systems containing glycol solution (up to 50%) that require the IBO MGB safety group to withstand increased fluid concentration and operating temperatures of up to 95°C.
- Systems with diaphragm expansion vessels up to 320 mm in diameter and weighing up to 45 kg, mounted directly on the safety group rail.
- Systems where gravity drainage of the medium from the safety valve to the sewer is required while keeping the discharge visible.
The IBO MGB 3 bar / MGB 6 bar safety group for boilers and heat pumps provides comprehensive pressure protection for heating systems.
Features, description, and technical data
The IBO MGB 3 bar / MGB 6 bar safety group is a complete wall-mounted device designed to work with a diaphragm expansion vessel and a heat source, such as a boiler or heat pump, in central heating systems. Its main function is to monitor and protect the system against excessive pressure increases by using a safety valve set below the maximum permissible pressure of the heat source, while also providing continuous pressure readings from the pressure gauge and automatic system venting.
The safety group body is made of CW614N brass, while the mounting rail is made of galvanized steel and is secured to the wall with wall plugs and screws, providing stable support for a diaphragm expansion vessel up to 320 mm in diameter and weighing up to 45 kg. The body features female threaded connections for connecting the system and the diaphragm expansion vessel, a pressure gauge with a range of 0–4 bar or 0–10 bar, a 1/2" safety valve set to 3 bar or 6 bar, and an automatic air vent with a shut-off valve.
The IBO MGB safety group is designed to operate at the maximum operating pressure corresponding to the version (3 bar or 6 bar), a maximum fluid temperature of 95°C, and a maximum glycol concentration of 50%. The components have been selected to enable gravity drainage of the medium from the safety valve to the sewer while keeping the discharge visible and eliminating the risk of negative pressure by avoiding a permanent connection to the sewer.
During installation, the IBO MGB safety group should be installed as close as possible to the heat source, on the supply or return pipe, in a way that prevents it from being accidentally shut off by a valve, and without any restrictions or additional shut-off valves between the device and the boiler or heat pump. The installation location must ensure safe discharge of the liquid stream from the safety valve without directing it at people nearby, while also providing convenient access for operation and periodic leak checks.
Operation of the IBO MGB safety group includes checking the tightness of the safety valve, air vent, and body approximately every 3 months, as well as testing the valve by turning the knob several times to remove any possible contaminants. If the air vent leaks, it is recommended to unscrew it, clean the inside, and reinstall it. All service work must be carried out by qualified personnel after the system has been cooled and emptied of fluid and pressure.
The IBO MGB safety group is subject to the Pressure Equipment Directive 2014/68/EU as a device designed in accordance with recognized engineering practice; therefore, it is not marked with the CE mark. The full operating manual is available on the Dambat website in the manuals section. Dambat is a trusted manufacturer of pumps and hydrotechnical equipment with quality certificates, confirming the high quality and reliability of the IBO MGB 3 bar / MGB 6 bar safety groups.
FAQ
What is the IBO MGB 3 bar / MGB 6 bar safety group used for?
The IBO MGB 3 bar / MGB 6 bar safety group is used to monitor pressure and protect the heating system against excessive pressure increases by means of a safety valve, pressure gauge, and automatic air vent, while also working with a diaphragm expansion vessel.
How do you select the appropriate IBO MGB safety group version for a system?
