Download PDFThe Reflex Refix DE 12/10 membrane expansion vessel is designed for closed circuits of utility and drinking water, where it balances volume changes and maintains stable pressure in the system. Thanks to the water being stored in a bladder, all parts in contact with the medium are corrosion-resistant, which extends the lifespan of the installation.
The Refix DE series vessels are particularly suitable for systems with increased oxygen content – such as underfloor heating, plastic piping, or brine circuits of heat pumps. This effectively limits corrosive damage to metal components and increases the operational safety of the entire system.
