Diaphragm expansion vessel REFIX DE-80, 80L, 10 bar / 70°C, threaded connection G1", blue, for DHW, fire protection, underfloor heating, geothermal, standing, with replaceable membrane 7306500

Expansion vessel for maintaining pressure stabilization in installations.

This Refix DE-80 expansion vessel, with a capacity of 80 liters, is designed to maintain stable pressure in water systems, including central heating, domestic hot water, underfloor heating, and geothermal systems. This is particularly important in installations that do not meet the strict standards of DIN 1988, as well as in systems requiring increased protection against corrosion. The device effectively eliminates changes in water volume due to temperature fluctuations and replenishes fluid losses in the installation.

The Refix DE vessel is characterized by a solid construction and high quality workmanship. Made of corrosion-resistant materials, it ensures long-lasting and trouble-free operation. The blue housing color makes it easy to identify the device in the installation. A replaceable diaphragm (compliant with PN-EN 13831) allows for easy maintenance and extends the life of the vessel. A G1" threaded connection ensures simple and tight installation.

Application and advantages:

• Versatility: ideal for DHW, fire protection, underfloor heating and geothermal installations.
• Corrosion protection: components in contact with water are protected against corrosion, guaranteeing durability and reliability.
• Replaceable diaphragm: possibility to replace the diaphragm after its service life is exceeded (from 50 liters).
• Safety: has a PZH certificate, confirming safety of use in contact with drinking water.
• Compliance with standards: approval in accordance with the pressure equipment directive 2014/68/EU.
• Pressure stability: maintains pressure in the installation within permissible limits, protecting against damage and ensuring comfort.
• Compensation for volume changes: compensates for changes in water volume caused by temperature changes, preventing stress in the installation.
• Replenishing losses: compensates for water losses during installation operation, maintaining a constant pressure level.

The Refix DE-80 vessel is a reliable solution for professionals and end-users looking for an effective way to stabilize pressure in water and heating systems. Its solid construction and compliance with applicable standards guarantee safe and long-lasting operation.
