22.5 Kg Trolley Mounted CO2 Fire Extinguisher

Where a trolley CO2 unit makes sense

A hand-held CO2 unit empties fast, so large risks call for a bigger charge. Mounting the cylinder on wheels gives the reach and duration of a big unit without asking staff to lift it. Typical sites include:

• Generator rooms, transformer yards and switch rooms
• Fuel stores, paint shops and chemical stores
• Aircraft hangars, ports and large workshops

CO2 is a clean agent. It smothers the fire by pushing out oxygen and cools as it expands, then leaves no residue on machines or electrical panels. It is not the right choice for deep-seated class A fires in wood or paper, where a powder or water unit does better.

Specification of the 22.5 Kg Trolley Mounted CO2 Fire Extinguisher

The table below holds the full data. The confirmed points are a 22.5 kg CO2 based charge, fire class C and B, a carbon steel body and an epoxy polyester powder coated surface.

Some values are typical for this type rather than confirmed for this model. Units like this usually use manual operation, squeeze lever style, at the hose end. The type table lists stored pressure or gas cartridge discharge, and a mild steel or aluminium cylinder is common in this class, although this listing names carbon steel.

Points to agree before you order

Buyers of wheeled CO2 units usually ask us about the hose length, horn type, wheel size and the test pressure stamped on the cylinder. We recommend sending the local fire code clause with your enquiry. Many national codes draw on the NFPA codes and standards, and we confirm which papers we can provide on our certifications and compliance page.

For a smaller clean-agent unit, see the 6.5 kg CO2 type fire extinguisher. If class A cover is also needed, compare the 25 kg DCP type fire extinguisher.

Export and tender supply

We make these units in China and ship them to Nigeria, Kenya, Ghana and other markets, often for government and tender contracts. We confirm the charge, Incoterm and delivery date before production, and each unit leaves in seaworthy export crating.
