How it works

A large cylinder on a wheeled frame feeds a hose reel and nozzle. The unit is either stored-pressure or cartridge-operated, where a separate gas cartridge pressurizes the agent when activated. One or two trained people wheel it to the fire, run out the hose and discharge. Because the agent quantity is so much larger, ratings can be very high on Class B — 240-B and above.

Who needs it

High-hazard sites under NFPA 10 and insurer requirements.

Codes, standards and listings

Canada: Rating per CAN/ULC-S508, with construction to the agent-specific ULC standard (ULC-S504 dry chemical, ULC-S503 CO2, ULC-S566 halocarbon); selection under the National Fire Code of Canada.
United States: Rating per UL 711, with construction to UL 299 (dry chemical), UL 154 (CO2) or UL 2129 (halocarbon); selection under NFPA 10.

What the market looks like

Amerex, ANSUL and Badger make wheeled units. They are bought through fire equipment dealers, usually specified by an insurer or a hazard assessment rather than chosen off a shelf.

Features that actually matter

Capacity: Roughly 50–350 lb of agent.
Hose and nozzle: Lets the operator fight the fire from a safer distance than a handheld allows.
Stored-pressure or cartridge-operated: Cartridge units stay unpressurized until used.
Agent options: Dry chemical, foam or clean agent, chosen by hazard.

What it really costs

Up front: No reliable public figure — get quotes.
Consumables: Recharge after any use. No reliable public figure — get quotes.
What else you'll need: Operator training.
Over five years: Annual service under NFPA 10 plus hose and cartridge checks. No reliable public figure — get quotes.

No public price source was checked; all cost lines need dealer quotes.

How it differs from the alternatives

Versus several handheld units: One trained operator with a wheeled unit delivers far more agent continuously than several people with handhelds.
Versus fixed suppression: Wheeled units need a person present; fixed systems act automatically. High-hazard sites often have both.

Buying it

Effort Moderate

Where: Fire equipment dealers only.

Lead time: Days to weeks; often a dealer order

Check what your insurer specifies before buying — the requirement often comes from them.

Installing it

Effort Easy

Time: Delivery and placement

You'll need: Level, firm staging area

Station it where it can be wheeled to the hazard over firm ground.

Living with it

Effort Moderate

NFPA 10 maintenance plus hose and cartridge checks, and refresher training for operators.

If not this, then what

Multiple large handheld extinguishersLower cost and no cart, with far less agent per person.
Fixed suppression systemsAutomatic protection for specific high-hazard equipment.

Caveats

Requires trained operators.
Heavy and difficult to move on rough ground.
No price source was checked; get dealer quotes.

Our verdict

If your insurer or hazard assessment calls for one, buy it from a dealer who will also train your people. An untrained operator gets little from a wheeled unit.

We don't take payment for placement and we don't sell these products. If you think we've got something wrong here, tell us — we'll correct it.
