The manifold safety groups combine an air vent (for automatic removal of air from the system, preventing corrosion and noise), pressure gauge with automatic safety shut-off, and a safety relief valve. With these elements, the system is able to detect when the pressure rises above 3bar and in turn releases excess fluid until the correct pressure is restored.

Supplied in versions to 50, 100, 200 and 350kW, and mounted via one female thread, the boiler safety groups are manufactured in CFC-free installation boxes, which are rated to Fire Protection Class B. Although supplied to 3bar as standard, additional set pressures can be supplied on request.
