## Summary description

CIMM AFE 35 L expansion (diaphragm) vessel designed for domestic hot water (c.w.u.) systems. Rated capacity 35 litres, pre-charge 1.5 bar and maximum working pressure 10 bar. Operating temperature range -10 to +100 °C. Used to absorb thermal expansion, maintain system pressure stability and protect boilers, heaters and pipework in residential and commercial hot water installations.

## Long description

The CIMM AFE 35 L expansion vessel for domestic hot water is designed to manage thermal expansion in closed potable hot water systems. With a nominal capacity of 35 litres and a factory pre-charge of 1.5 bar, this diaphragm-type vessel reduces pressure fluctuations, helps prevent short cycling of boilers and stabilises system pressure within the operating range. It is intended for installation in residential and light commercial c.w.u. systems where protection of heaters, boilers and pipework is required.
Advantages
The diaphragm design separates the water from the gas cushion, preventing waterlogging and ensuring consistent performance over time. A working pressure rating of up to 10 bar and an operating temperature range from -10 °C to +100 °C make the vessel suitable for a wide range of hot water conditions. The factory pre-charge provides a baseline pressure that simplifies commissioning and reduces the need for frequent adjustment during normal operation.
Suitable for
Domestic hot water (c.w.u.) systems in single-family homes and apartments
Small commercial hot water installations such as offices or small retail premises
Systems requiring pressure stabilisation and protection of boilers, heaters and piping
Retrofit projects replacing existing expansion vessels with compatible capacity
Key specifications
Nominal capacity: 35 litres
Pre-charge pressure: 1.5 bar (factory set)
Maximum working pressure: 10 bar
Operating temperature range: -10 °C to +100 °C
Type: Diaphragm (membrane) expansion vessel for potable hot water
How to use
Install the expansion vessel in accordance with applicable plumbing and heating standards, positioned where it can be accessed for maintenance and pressure checks. Connect the vessel to the hot water system at a location that experiences system pressure changes, typically near the boiler or primary storage cylinder. Before commissioning, verify the vessel pre-charge with a pressure gauge and adjust to match the system’s static pressure if necessary. After installation, pressurise the system and check for leaks and correct operation while monitoring pressure behaviour during heating cycles.
Usage recommendations
Regularly inspect the vessel for external damage or corrosion and check the air pre-charge pressure annually or after any system maintenance. Replace the vessel if the diaphragm shows signs of failure, persistent pressure loss occurs, or the vessel becomes waterlogged. Follow local regulations for potable hot water components and use qualified personnel for installation and servicing to ensure system integrity and safety.
