CIMM AF CE 24 24L Pressure Tank – 8 Bar

The CIMM AF CE 24 is a compact 24-litre vertical membrane pressure tank for sanitary-water and booster pump systems. It is rated to 8 bar, supplied with a 1.5 bar factory pre-charge, and fitted with a male 1-inch Gas connection and replaceable membrane.

Where the AF CE 24 fits

This is the compact model in the selected CIMM range. It may suit smaller booster-pump and hydropneumatics installations where floor space is limited. Tank capacity still has to be checked against pump flow, cut-in and cut-out pressures, and the required drawdown; the 24-litre label alone is not a sizing recommendation.

Confirmed technical data

What to check before ordering

• Treat 24 litres as nominal vessel volume, not the amount of usable water available between pump cycles.
• Have the installer verify the pre-charge against the final system settings before commissioning.
• Confirm the vessel size against the pump duty and required drawdown.

Manufacturer-listed applications

CIMM lists the AFC/AF range for hot and cold sanitary-water circuits, booster pump systems, heating systems and refrigeration circuits, within the model’s stated pressure and temperature limits.

Frequently asked questions

What is the CIMM AF CE 24?

It is a 24-litre vertical membrane pressure tank for sanitary-water and booster pump systems. CIMM rates it to 8 bar with a standard 1.5 bar pre-charge.

Is the full 24 litres available as usable water?

No. The 24-litre figure is the vessel’s nominal volume. Actual drawdown depends on pre-charge and the pump’s cut-in and cut-out pressures.

Which connection size does OPAR stock?

OPAR stocks the male 1-inch Gas connection. This corresponds to CIMM manufacturer code 502412/001.

Can the membrane be replaced?

Yes. CIMM specifies an interchangeable membrane manufactured according to DIN 4807.
