## Summary description

CIMM AFE 50 L diaphragm (expansion) vessel designed for domestic hot water (c.w.u.) systems. Rated volume 50 litres, precharge 1.5 bar, maximum working pressure 10 bar, and operating temperature range −10 to +100°C. Used to absorb thermal expansion, stabilize system pressure and protect plumbing in hot-water installations and water heaters.

## Long description

The CIMM AFE 50 L diaphragm vessel is designed for domestic hot water systems to absorb thermal expansion and stabilise pressure in closed water circuits. With a rated volume of 50 litres and a factory precharge of 1.5 bar, the vessel supports safe operation of water heaters and plumbing by accommodating volume changes that occur as water temperature rises. The design allows operation across a wide temperature range and is suitable for integration into household and light-commercial hot water installations.
Advantages
The diaphragm construction separates the water and the gas cushion, minimising contact and reducing corrosion risk while providing consistent pressure damping. A 50-litre capacity offers a balance between compact footprint and adequate expansion volume for typical domestic hot-water systems. The vessel's rated maximum working pressure enables reliable operation in systems up to 10 bar, and the specified temperature range supports both low-temperature and high-temperature applications within the stated limits.
Suitable for (tasks / use cases)
 Domestic hot water systems (c.w.u.) where thermal expansion needs control
 Installation with water heaters, boilers, and tank-type storage heaters
 Systems requiring pressure stabilisation to protect fittings and valves
 Retrofit projects to add expansion capacity to existing plumbing

How to use
Install the diaphragm vessel on the cold-water side or as recommended by system design, following local plumbing codes and manufacturer installation practices. Ensure the vessel precharge matches the static pressure of the installation or adjust the gas precharge accordingly before commissioning. Mount the vessel on a stable surface or bracket, connect using appropriate fittings, and bleed air from the system. Regularly check precharge pressure and system connections as part of scheduled maintenance to ensure continued performance.
Usage recommendations
Verify compatibility with the system's maximum allowable pressure and operating temperature. Before installation, set or confirm the gas precharge to match the static inlet pressure and perform pressure and leak tests after connection. Periodic checks of the precharge and visual inspection of connections are recommended to maintain reliable operation.
