Diaphragm expansion vessel BASEFLEX-25, 25L, 1.5/6 bar / 70°C, threaded connection G3/4" male, red RAL 3002, for heating and cooling systems, vertical mounting 25303

Diaphragm expansion vessel for heating and cooling systems

This BASEFLEX-25 diaphragm expansion vessel with a capacity of 25 liters is designed for use in closed heating and cooling systems. Its construction allows for compensation of changes in fluid volume in the installation, maintaining stable working pressure. Made of high-quality materials, it ensures reliable operation and long service life.

Construction and application

The BASEFLEX-25 vessel is characterized by a solid welded construction and powder coating in red RAL 3002 – a white RAL9010 version is also available. Filled with nitrogen, which ensures longer maintenance of the initial pressure at 1.5 bar. Suitable for operation with a maximum working pressure of 6 bar and a continuous operating temperature from -10 to 70°C. The EPDM rubber membrane guarantees resistance to glycol (up to 50% concentration) and ethanol (up to 30% concentration). A G3/4”M threaded connection facilitates integration with the existing installation.

The vessel is designed for vertical mounting and meets the requirements of EN13831 standard and Pressure Equipment Directive PED 2014/68/EU. This gives you the confidence that the product is safe and reliable.

Key features and benefits:

• Expansion compensation: Maintains constant pressure in the installation, absorbing changes in fluid volume caused by temperature changes.
• Versatility: Suitable for both heating and cooling systems.
• Chemical resistance: The EPDM membrane is resistant to glycol and ethanol, allowing it to be used in various heating systems.
• Safety: Meets European standards and has PED 2014/68/EU certification.
• Durability: Solid welded construction and powder coating ensure long device life.
• Pre-filled with nitrogen: Ensures stable initial pressure for a longer time, minimizing the need for adjustment.
• Easy installation: G3/4”M threaded connection facilitates connection to the installation.
• Compliance with standards: Meets the requirements of EN12828 standard for closed heating systems.
