Diaphragm expansion vessel FLOFIX-8, 8L, 4.0/10 bar / 110°C, threaded connection G3/4" male, white RAL 9010, for DHW systems, vertical mounting 25290

Expansion vessel FLOFIX-8 – a reliable solution for DHW and central heating systems

The FLOFIX-8 vessel is a key component of closed heating and domestic hot water systems, designed to compensate for changes in fluid volume due to temperature fluctuations. This maintains stable pressure in the system, protecting it from damage and ensuring efficient operation. Made of high-quality materials and filled with nitrogen, it guarantees long-lasting and trouble-free operation.

Construction and application

The FLOFIX-8 diaphragm expansion vessel with a capacity of 8 liters and a maximum working pressure of 10 bar is designed for wall mounting. It has a threaded G3/4”M connection, which facilitates integration with the existing installation. Made of durable steel and powder-coated in white (RAL 9010), it provides an aesthetic appearance and corrosion resistance. The EPDM rubber membrane guarantees durability and resistance to glycol (up to 50% concentration). It can be used in both central heating and domestic hot water systems.

Advantages and benefits

• Stable pressure: Compensation for changes in fluid volume maintains constant pressure in the installation, minimizing the risk of pump failure or damage to system components.
• Durability and reliability: Nitrogen filling extends the life of the vessel, maintaining optimal pre-pressure for longer.
• Versatility: Suitable for use in both DHW and central heating installations, as well as systems with glycol additive (up to 50%).
• Easy installation: The threaded G3/4”M connection ensures quick and easy connection to the installation.
• Corrosion resistance: Powder coating in white (RAL 9010) protects the vessel from external factors.
• Safety: Compliance with the Pressure Equipment Directive PED 2014/68/EU confirms a high level of safety.
• Durable membrane: The EPDM membrane is resistant to high temperatures (up to 70°C) and glycol action.
• Stainless steel flange: Provides additional durability and corrosion resistance in an area particularly exposed to moisture.

Whether you are a plumber looking for a reliable component for an installation at a customer's site, or an end user who cares about the proper functioning of the heating system – the FLOFIX-8 vessel is a sure choice.
