Expansion vessel Refix DE-8 – reliable pressure maintenance in the installation

The Refix DE-8 expansion vessel is a key element of the installation, ensuring stable pressure and safe operation of the entire system. The device effectively eliminates pressure fluctuations, compensates for changes in water volume and compensates for losses, protecting against the effects of underpressure and cavitation. It is an ideal solution for both installers and users who value reliability and comfort of use.

Versatile application in various systems

The Refix DE-8 vessel is perfect for a wide range of applications, including:

• domestic hot water (DHW) installations,
• fire protection installations,
• underfloor heating systems,
• geothermal installations.

Thanks to compliance with PN-EN 13831 and anti-corrosion protection, the vessel is suitable even for installations with increased requirements. It also has a PZH certificate, which confirms its safety for health.
