Description
FIX CO/CWU 36 diaphragm expansion vessel – expansion vessel for IPRO heating and domestic water systems
The IPRO FIX CO/CWU 36 diaphragm expansion vessel is designed for closed heating and solar systems, as well as hot and cold potable water systems. Inside the steel body, a non-replaceable, certified butyl membrane absorbs the increase in water volume during heating and protects the system against excessive pressure increase.
Who is it for?
- Heating system installers – the FIX CO/CWU expansion vessel absorbs the increase in water volume in a closed central heating system and protects the system against pressure increases.
- Solar system contractors – the membrane's resistance to high temperatures and compatibility with glycol concentrations of up to 50% allow the vessel to be used in solar systems.
- Domestic hot water systems – the certified butyl membrane allows use in potable water systems and compensates for the expansion of hot water.
- Service providers and installation companies – the 3/4" stainless steel connection and adjustable pre-charge pressure simplify installation and vessel selection for the system.
Application
The FIX CO/CWU 36 diaphragm expansion vessel is designed for closed heating and solar systems, as well as hot and cold potable water systems. It maintains and equalizes pressure changes resulting from the increase in the volume of water or heating medium during heating. The vessel can operate in systems containing up to 50% glycol.
The tank is installed vertically and works with boilers, heat pumps, solar collectors, and domestic water systems. The certified butyl membrane separates the water from the air cushion and protects the system against the effects of pressure fluctuations.
Features of the FIX CO/CWU diaphragm expansion vessel – description and technical data
The FIX CO/CWU 36 diaphragm expansion vessel is a diaphragm expansion vessel with a steel body coated with a two-layer epoxy-polyurethane coating. Inside is a non-replaceable, certified butyl membrane with high tensile strength and resistance to high temperatures, while the connection is made of stainless steel.
The membrane separates the water or heating medium from compressed air, allowing the vessel to absorb the increase in volume and maintain stable pressure in a closed system. The tanks comply with the requirements of the PED 2014/68/EU Pressure Equipment Directive and EN 13831.

Frequently asked questions (FAQ) – IPRO FIX CO/CWU diaphragm expansion vessel
What is the FIX CO/CWU 36 diaphragm expansion vessel used for?
The FIX CO/CWU 36 diaphragm expansion vessel absorbs the increase in the volume of water or heating medium during heating and maintains stable pressure in closed heating and solar systems, as well as in hot and cold potable water systems.
Is the FIX CO/CWU vessel suitable for both heating and domestic water?
Yes. The certified butyl membrane allows the vessel to be used in central heating and solar systems, as well as in hot and cold potable water systems.
What is the pre-charge pressure, and can it be adjusted?
The vessels are supplied with a factory air pre-charge pressure of 2.5 bar. This pressure should be adjusted to the parameters of the specific system using the air valve.
