Crafted with an ottone (brass) connection of 3/4 inch, the OT090105 CO HS 25L diaphragm vessel is engineered to effectively manage water volume fluctuations within the closed circuit of a central heating system. By absorbing changes in water volume that occur due to temperature variations, it plays a crucial role in maintaining a consistent pressure throughout the system.

The vessel's pre-pressurized diaphragm is designed to respond dynamically to the thermal expansion of water. As the system heats and water expands, the diaphragm flexes, allowing excess water to enter the tank and alleviating potential pressure build-up. Conversely, as temperatures decline and water contracts, the diaphragm retracts, pushing the water back into the system. This process not only helps in preserving the integrity of the heating system but also contributes to reducing energy consumption by minimizing the workload on heating components.

With a comprehensive selection of diaphragm vessels available, this range caters to a variety of heating system requirements and sizes. The product's standard European Article Number is 5902188411409, ensuring ease of identification and compatibility checks for installation and replacement purposes.
