The Reflex Refix DE 18/10 membrane expansion vessel is designed for closed systems of utility and operational water, such as fire and operational pipelines or underfloor heating. It separates water from the gas space using an internal bladder and maintains stable pressure in the system.

All parts of the vessel that come into contact with water are corrosion-resistant, ensuring long life even in circuits with increased oxygen content. The vessel operates with a maximum working pressure of 10 bar and is equipped with a threaded connection G3/4".
