## Summary description

Diaphragm expansion vessel CIMM ERE 06L designed for central heating (CO) systems. Volume 6 liters with factory pre-charge 1.5 bar and maximum operating pressure 4 bar. Rated for fluid temperatures from -10 °C to +100 °C. Used to absorb thermal expansion, stabilize system pressure and protect pumps and valves in boilers, radiators and closed heating circuits.

## Long description

The Expansion vessel CIMM ERE 06L for central heating is a diaphragm-type pressure vessel with a nominal volume of 6 liters. It is designed for closed heating (CO) systems to absorb thermal expansion of the heating medium, stabilise system pressure and protect circulation pumps, valves and heat sources. The vessel comes factory pre-charged to 1.5 bar and supports maximum operating pressure up to 4 bar, with a working temperature range from -10 °C to +100 °C.
Advantages
The diaphragm construction separates the gas and liquid compartments to reduce corrosion and maintain consistent pressure response throughout thermal cycles. A compact cylindrical body and standard connection make it suitable for retrofit or new installations where space is limited. Factory pre-charge ensures predictable initial system conditions and reduces setup time during commissioning. Designed for closed heating systems, the vessel helps prevent frequent pump cycling and pressure fluctuations that can lead to wear.
Suitable for
Domestic and small commercial central heating systems
Boilers, heat pumps and hydronic radiator circuits
Closed-loop heating installations requiring pressure stabilisation
Key specifications
Type: diaphragm expansion vessel for central heating
Nominal volume: 6 liters
Factory pre-charge pressure: 1.5 bar
Maximum operating pressure: 4 bar
Operating temperature range: -10 °C to +100 °C
Intended medium: heating water or glycol mixtures compatible with closed systems
How to use
Install the expansion vessel in a dry, accessible location within the heating system, typically on the return line near the boiler or pump according to local practice. Prior to installation, verify the system’s required pre-charge and initial pressure; the vessel’s factory pre-charge is 1.5 bar and can be adjusted with a suitable pump or pressure tool if system design requires a different value. Secure the mechanical connection using appropriate fittings and sealing methods, then fill and purge the heating circuit following standard procedures. After filling, check for leaks and confirm the vessel and system reach stable pressure during a heat-up cycle.
Usage recommendations
Verify compatibility of the heating fluid (water or approved antifreeze mixtures) with the vessel materials and avoid exceeding the maximum operating pressure of 4 bar or the maximum temperature of +100 °C. Periodically check pre-charge pressure when the system is cold and inspect for signs of diaphragm failure, external corrosion or leakage during routine maintenance.
