Diaphragm expansion vessel FLEXCON SOLAR-18, 18L, 2.5/8 bar / 110 °C, threaded connection R3/4", white RAL 9010, for solar installations, vertical mounting 16062

Expansion vessel with diaphragm is a key component in solar and central heating systems, ensuring the safety and stability of the system. The FLEXCON SOLAR-18 model with a capacity of 18 liters, designed by Flamco, is perfect for systems with solar collectors, but also finds application in CH installations. Its construction based on a butyl rubber (IIR) membrane guarantees reliability and corrosion resistance.

The vessel is adapted to work with glycol at a concentration of up to 50%, making it an ideal solution for installations protected against freezing. It withstands operating temperatures in the range of -10 to 110°C, allowing its use in various conditions. A threaded R3/4" connection facilitates installation and integration with the existing system. A pre-pressure of 2.5 bar and a maximum working pressure of 8 bar ensure optimal operating conditions for the installation.

• Versatility: Suitable for both solar, central heating and cooling installations.
• Durability: Manufactured in accordance with the Pressure Equipment Directive 2014/68/EU, which confirms its high quality and safety.
• Resistance: The butyl rubber membrane is resistant to glycol and provides long-term tightness.
• Convenient installation: A threaded R3/4" connection ensures quick and easy connection to the installation.
• Factory tested: Each vessel undergoes rigorous quality tests, guaranteeing its reliability.
• Color: White (RAL 9010) – aesthetic appearance matching most installations.

The FLEXCON SOLAR-18 vessel complies with EN13831 standard and has a galvanized ring connecting the two halves, which further increases its mechanical strength. The set includes mounting material, facilitating installation. The vessel is designed for vertical mounting and is characterized by compact dimensions (height 323 mm, diameter 297 mm). It is worth remembering that the vessel does not have a safety valve or manometer – these elements should be selected separately depending on the specifics of the installation.
