Expansion Vessel HS 25L – Connection 3/4 Inch

The OT090105 CO HS 25L diaphragm vessel with a 3/4 inch brass connection is specifically designed to manage water volume changes within a central heating system’s closed circuit. It plays a vital role in maintaining stable system pressure by absorbing water volume fluctuations caused by temperature changes. The vessel features a pre-pressurized diaphragm that responds effectively to the thermal expansion and contraction of water. When the system heats up and water expands, the diaphragm flexes, allowing excess water to enter the tank and preventing pressure build-up. As the system cools and water contracts, the diaphragm pushes the water back into the system. This enhances the heating system's integrity and reduces energy consumption by lessening the load on heating components. With a wide range of diaphragm vessels available, this product line accommodates different heating system needs and sizes. Its standard European Article Number, 5902188411409, ensures easy identification and compatibility checks for both installation and replacement.
