45kg CO2 Mobile Fire Extinguisher

Description

The 45kg CO2 mobile fire extinguisher is the large-scale zero-residue solution for server halls, large electrical switchrooms, data centres, transformer bays, and industrial environments where chemical powder residue would cause catastrophic secondary damage. CO2 extinguishes by displacing oxygen with no residue whatsoever — no powder, no foam, no cleanup. At 150kg gross weight on a solid rubber wheel trolley, this is a two-person deployment unit for facility protection teams.

Approved to AS/NZS 1841.6. Suitable for Class B fires (flammable liquids — petrol, oil, solvents) and Class E fires (electrically energised equipment). Not rated for Class A fires.

Compliance & Servicing

Approved to AS/NZS 1841.6. CO2 mobile extinguishers must be inspected every 6 months and serviced annually in accordance with AS 1851 by a licensed fire protection technician. High-pressure CO2 cylinders require hydrostatic pressure testing every 5 years at 250 Bar (25MPa). Given the high-value environments where CO2 mobiles are deployed, keeping service records current is critical for both compliance and insurance purposes.

Frequently Asked Questions

Where 45kg CO2 Mobile Extinguishers Are Specified

• Data centres and large server halls
• High-voltage electrical switchrooms and transformer bays
• Industrial electrical control rooms
• Printing facilities and large photocopier rooms
• Paint spray booths and flammable liquid storage areas
• Facilities where zero residue is mandatory for operational continuity
• Any high-value electrical installation where powder would cause irreparable damage

Why specify a CO2 mobile instead of an ABE mobile for an electrical environment?

ABE dry chemical powder is highly corrosive and will irreparably damage electronic equipment — circuit boards, hard drives, precision sensors, and switchgear components. In a data centre or electrical switchroom, discharging ABE powder could destroy far more equipment than the fire itself. CO2 leaves zero residue and causes no secondary damage to equipment. The clean-up after a CO2 discharge is minimal: ventilate the space and you’re done. For any environment where the value of the equipment exceeds the cost of the fire protection, CO2 is the appropriate agent.

Is a 45kg CO2 mobile safe to discharge in a room with people present?

CO2 at high concentrations displaces oxygen and can cause unconsciousness or asphyxiation. In a large-capacity mobile application, the discharge volume is significant — a 45kg CO2 release will create a hazardous atmosphere in any enclosed space. Always ensure the space is evacuated before discharge, discharge from outside the room where possible, and ventilate thoroughly before re-entering. CO2 mobile units in data centres and server halls are often part of a suppression scheme with evacuation signalling — confirm integration with your fire protection engineer.

What maintenance does a 45kg CO2 mobile extinguisher require?

6-monthly inspection and annual full service by a licensed fire protection technician in accordance with AS 1851. The high-pressure cylinder must undergo hydrostatic pressure testing every 5 years at 250 Bar (25MPa) — this is a mandatory requirement for seamless high-pressure CO2 cylinders. Given the cylinder’s 150kg gross weight, pressure testing is typically performed on-site or by an accredited test house. Do not attempt to transport a pressurised 45kg CO2 cylinder without proper restraints and documentation.

What is the difference between a 45kg CO2 mobile and portable CO2 extinguishers for a server room?

Portable CO2 units (2kg, 3.5kg, 5kg) are appropriate for individual workstations, small server cupboards, and point-of-use suppression by a single person. The 45kg mobile is for large server halls, data centres with multiple racks, or transformer bays where a 5kg portable simply doesn’t have the agent volume to control a serious fire. The 45kg provides facility-level suppression capacity and is deployed by trained personnel as a primary or secondary intervention tool. Most large data centres specify both portables (for early intervention) and a mobile (for serious events).

Is delivery available for this product?

Yes — the 45kg CO2 mobile is available for delivery Australia-wide. At 150kg gross weight, this requires freight with appropriate handling. It will be delivered to the kerb or dock. Ensure that a forklift or pallet jack and adequate clearance is available for receipt.
