Boiler safety groups

Boiler safety groups (KSG) are pre-assembled units designed to protect closed heating systems in accordance with DIN EN 12828. They combine a 3.0 bar safety valve, a pressure gauge (0–4 bar), and an automatic air vent mounted on a compact manifold. The safety groups are suitable for heating systems with outputs of 50, 100, or 200 kW. Depending on the version, the bodies are made of galvanized steel or brass and feature CFC-free insulation, classified as fire protection class B2 according to DIN 4102.
