Diaphragm expansion vessel FLOFIX-35, 35L, 4.0/10 bar / 110°C, threaded connection G3/4" male, white RAL 9010, for DHW installations, standing 25294

Expansion vessel for DHW and central heating systems

This Flofix-35 diaphragm expansion vessel with a capacity of 35 liters is a reliable solution for stabilizing pressure in closed heating and cooling systems, as well as in domestic hot water systems. The welded construction and high-quality EPDM membrane ensure long-lasting and trouble-free operation. The vessel is pre-filled with nitrogen, which extends the period of maintaining the correct pre-pressure, minimizing the need for adjustment.

Construction and application

The Flofix-35 vessel is designed to compensate for changes in water volume in the installation caused by temperature fluctuations. This maintains a constant working pressure, protecting installation components from damage. The G3/4”M threaded connection facilitates quick and easy installation without the need for additional gaskets or adapters. The standing construction with legs ensures stability and convenient installation, and the white color (RAL 9010) allows for aesthetic integration into the surroundings.
