Diaphragm expansion vessel FLOFIX-25, 25L, 4.0/10 bar / 110°C, threaded connection G3/4" male, white RAL 9010, for DHW installations, vertical mounting 25293

FLOFIX expansion vessels – reliable protection for DHW systems.

FLOFIX expansion vessels are essential components in every domestic hot water system, providing stable pressure and safe operation. The FLOFIX-25 model with a capacity of 25 liters, a maximum working pressure of 10 bar and a pre-pressure of 4 bar, is an ideal solution for both installers and end-users looking for a reliable and efficient device. Welded construction and EPDM membrane guarantee long-lasting and trouble-free operation.

Construction and application

The FLOFIX-25 diaphragm tank is designed to compensate for changes in water volume in the installation resulting from temperature fluctuations. This maintains a constant working pressure, protecting system components from damage caused by excessive pressure or sudden drops. Filling with nitrogen ensures longer pre-pressure stability, and the G3/4”M threaded connection facilitates trouble-free installation without the need for additional gaskets or adapters. The white housing color (RAL 9010) provides an aesthetic appearance and easy integration with the surroundings. The tank is designed to operate at temperatures from -10°C to 70°C, allowing it to be used in a wide range of operating conditions. The possibility of using glycol up to 50% concentration expands the scope of applications, allowing installation in systems protected against freezing.
