Mobile (Wheeled) Fire Extinguishers
Designed for rapid, high-capacity response to large fires, mobile extinguishers are standard for workshops, warehouses, fuel/solvent areas and industrial sites. Options include ABC multi-purpose powder, foam (Class A/B) and CO₂ with long hose, nozzle/lance and robust chassis for TS/EN-compliant performance.
Selection Guide: The Right Mobile Unit for Your Area
Choose extinguishing medium and capacity by risk type, potential fire size and reach requirements.
| Area / Scenario | Suggested Medium | Typical Capacity | Note |
|---|---|---|---|
| Workshop / Production lines | ABC Powder | 25–50 kg | Mixed A/B/C risks; fast knockdown |
| Warehouse / Logistics | ABC Powder + Foam | 25–50 kg (ABC), 50 L (foam) | Solid + flammable liquid combinations |
| Fuel / Solvent zones | Foam | 50–100 L | Class B; film layer helps prevent re-ignition |
| Electrical panel / Substation | CO₂ | 30–45 kg | Leaves no residue; ensure ventilation |
| Yard / Port areas | High-capacity ABC | 50 kg+ | Prefer long hose set and lance |
Technical Specifications & Comparison
Figures are typical and vary by brand/model. Refer to the product data sheet for exact values.
| Item | ABC Powder | Foam | CO₂ | Notes |
|---|---|---|---|---|
| Capacity | 25–50 kg | 50–100 L | 30–45 kg | Match to area and risk size |
| Discharge time | 20–40 s | 60–120 s | 20–35 s | Depends on nozzle setting & temperature |
| Hose length | 5–10 m | 10–20 m | 5–10 m | Varies with lance/nozzle |
| Effective range | 3–8 m | 4–10 m | 2–5 m | Indoor/outdoor conditions affect reach |
| Suitable fire classes | A/B/C | A/B | B/E | Do not use foam on live electricals |
Maintenance & Periodic Checks
Reliability depends on regular visual/functional checks and proper records.
| Interval | Action | Description |
|---|---|---|
| Monthly (visual) | Gauge/seal, hose, wheels | Pressure, cracks/cuts, wheel bearings and nozzle |
| Every 6 months | Functional test | Leak, flow, connections and valve operation |
| Annually | Service / refill | Replace medium by type and update labels |
| Every 5 years* | Hydrostatic test | Cylinder strength (*depends on model/regulation) |
| Foam units | Concentrate quality | Annual sample and induction ratio test |
Safety Notes
- Work with the wind at your back; keep an open egress.
- Do not use foam on electrical fires; choose CO₂ instead.
- Check couplings and nozzle lock before each use.
Placement Tips
- Place for easy access without blocking escape routes.
- Large wheels and a pull handle help overcome thresholds.
- Plan dual units in high-risk, high-load zones.
Frequently Asked Questions
25 kg or 50 kg? ▾
25 kg moves easier and suits small/medium risks. 50 kg provides higher flow and duration for wide areas and warehouses.
Foam or ABC powder? ▾
Choose foam where Class B (flammable liquids) dominate; for mixed risks, multi-purpose ABC is versatile. Never use foam on energized equipment.
Where should CO₂ mobile units be preferred? ▾
In areas where no residue is desired such as panels, UPS rooms and labs. Ensure ventilation—CO₂ can be asphyxiating in confined spaces.
