Diaphragm expansion vessel REFIX DE-50, 50L, 10 bar / 70°C, threaded connection G1", blue, for DHW, fire protection, underfloor heating, geothermal, standing, with replaceable membrane 7306005

Expansion vessel for DHW, heating and geothermal systems

The Refix DE-50 diaphragm tank is a reliable device designed to maintain stable pressure in domestic water, fire protection, underfloor heating and geothermal installations. This is particularly important in systems that do not meet the requirements of DIN 1988 standard. Its construction based on a bag membrane effectively compensates for changes in water volume caused by temperature and compensates for water losses in the installation. This protects installation components from damage and extends their service life.

Construction and application

The Refix DE-50 tank is made of powder-coated steel, which guarantees corrosion resistance. Parts in contact with water are additionally protected, making them suitable for installations with increased requirements in terms of anti-corrosion protection. Equipped with a replaceable membrane (from a capacity of 50 liters), the tank is easy to service and maintain. Designed for standing installation, which ensures stability and easy access. It has a G1" threaded connection, making it easy to integrate with an existing installation. Approval in accordance with Directive 2014/68/EU regarding pressure equipment and PZH certificate confirm its safety and high quality.

Key features and benefits

• Versatility: ideal for DHW, fire protection, underfloor heating and geothermal installations - one tank for many applications.
• Corrosion protection: protected parts in contact with water ensure long-term reliability even in difficult conditions.
• Replaceable membrane: from a capacity of 50 liters allows easy replacement of the membrane, extending the life of the tank and reducing operating costs.
• Safety: has approval in accordance with the pressure equipment directive and PZH certificate - a guarantee of safe operation.
• Stable pressure: maintains constant pressure in the installation, protecting devices from damage caused by pressure fluctuations.
• Volume compensation: compensates for changes in water volume resulting from temperature changes, preventing stress from building up in the installation.
• Easy installation: G1" threaded connection facilitates integration with an existing installation - saves time and installation costs.
