The Cimm AFE CE 80 is an 80 litre potable water expansion vessel built to absorb pressure fluctuations in sealed sanitary water systems, protecting pumps, pipework and fittings from the stress of repeated thermal expansion. It's approved under WRAS and ACS for use with drinking water, making it a straightforward specification choice for domestic and light commercial installations where potable water safety has to be demonstrable, not just assumed.
The vessel is manufactured to PED 2014/68/UE and EN 13831 and arrives pre-charged to 2.5 bar, ready to be set to match your system's working pressure before commissioning. It carries a maximum operating pressure of 10 bar and a working temperature range of -10°C to +100°C, so the same unit covers both hot and cold sanitary circuits as well as booster set and pressurised storage applications.
At 80 litres it's sized for larger domestic properties and light commercial setups — unvented cylinder installations, booster sets, and multi-outlet systems where a smaller vessel would cycle too frequently. Like other vessels in the AFE CE range, it uses a replaceable internal membrane design with a Schrader valve for pre-charge adjustment, which is worth checking periodically as part of routine system maintenance rather than treating as a fit-and-forget component.
Sizing an expansion vessel correctly is what stops a pump short-cycling and wearing out early — the 80 litre capacity here is built for systems where a smaller vessel would be under-specified. WRAS and ACS approval means it's a defensible choice for potable installations without needing to source separate documentation later, and the wide -10°C to +100°C range means the same vessel works whether it's sat on a cold water booster set or a hot sanitary circuit. The replaceable membrane and accessible Schrader valve also mean it's serviceable rather than disposable — the pre-charge can be checked and topped up as part of normal system maintenance instead of replacing the whole vessel.
