Suitable for residential and light-commercial boilers, radiators and closed hot-water circuits.

## Long description

CIMM ERE 35L is a diaphragm expansion vessel designed for central heating systems with a nominal volume of 35 litres. It accommodates thermal expansion of heating water, maintains system pressure within safe limits and protects boilers, radiators and piping in closed hot-water circuits. The vessel is suitable for residential and light-commercial installations where a compact, durable expansion solution is required and where operating pressures range between 1.5 and 5 bar and temperatures vary from −10 to +100°C.
Advantages
The diaphragm design separates the working gas from the heating fluid, reducing the risk of corrosion and gas contamination. A 35-litre capacity provides sufficient buffering for small to medium-sized heating installations, while the specified pressure and temperature ratings ensure compatibility with a wide range of modern boilers and radiators. Construction materials and sealing components are chosen for resistance to repeated pressure cycles and thermal stress, supporting reliable long-term operation.
Suitable for
Domestic central heating systems and single-family homes
Light-commercial heating circuits and small apartment blocks
Integration with wall-hung and floor-standing boilers
Closed hot-water circuits in radiators and underfloor heating
Key specifications
Nominal volume: 35 litres
Operating pressure range: 1.5–5 bar
Temperature range: −10 to +100 °C
Diaphragm (bladder) type construction
Compact cylindrical vessel form factor suitable for wall or floor mounting
How to use
Install the expansion vessel on the return line of the heating circuit or at the location recommended by the system designer, ensuring correct orientation and secure mounting. Before commissioning, set the pre-charge pressure of the vessel’s gas side to match the static pressure of the heating system, following the boiler manufacturer’s guidance. Verify tightness of hydraulic connections and gradually fill and pressurise the system, monitoring pressure behaviour during a heating cycle to confirm the vessel compensates thermal expansion as intended. Perform routine inspections of the pre-charge and visible connections according to the heating system maintenance schedule.
Usage recommendations
Match the vessel pre-charge to the static system pressure and check it periodically. Use the vessel within the stated pressure and temperature limits, and follow local regulations and the boiler manufacturer's instructions for installation and safety. If uncertain about sizing or installation, consult a qualified heating engineer.
