✓ GB / ISO 9001 / CE
The CA-FIRE PY series portable foam fire extinguishing system is a self-contained, mobile suppression unit that stores foam concentrate in an integrated bladder tank and delivers a precisely proportioned foam-water mixture to the fire through any compatible discharge device — foam gun, foam generator or foam monitor. Unlike fixed foam suppression installations, this portable foam system can be repositioned and redeployed across a site as operational requirements change, making it the practical first-choice solution for facilities where fire risk locations shift, where fixed infrastructure is unavailable, or where a mobile backup to a fixed system is needed for redundancy. Eight models cover foam injection durations from 10 to 36 minutes at 4 L/s or 8 L/s, in 3% and 6% mixing ratios. No electricity required. Wheeled frame deployable by a single operator.

How the Portable Foam Fire Extinguishing System Works
The PY series portable foam fire extinguishing system operates on the same fully hydraulic bladder tank proportioning principle as CA-FIRE’s fixed PHY/PHYM series — no electricity, no diesel engine, no electronic controls. Ready the moment water pressure is applied.
|
1
Standby — Bladder pre-charged with foam concentrate The rubber bladder inside the tank is filled with foam concentrate at the factory or after each recharge. The unit is stored on its wheeled frame at the designated deployment location — no connections, no power, no standby maintenance required. |
2
Deploy — Wheel to fire location, connect water supply A single operator wheels the unit to the fire location, connects a fire hose water supply to the system inlet and connects the selected discharge device — foam gun, foam generator or monitor — to the outlet. No tools required. |
|
3
Discharge — Venturi proportioner delivers precise 3% or 6% foam Opening the water supply valve applies water pressure to the outside of the bladder, squeezing concentrate into the venturi proportioner at the same pressure as the incoming water. The proportioner delivers a consistent 3% or 6% foam solution immediately — no warm-up, no calibration, no adjustment. |
4
Recharge — Unused concentrate retained, refill and redeploy After suppression, any unused concentrate in the bladder is in full-quality condition — water never entered the concentrate side. Rinse the discharge device, refill the bladder, and the unit is ready for the next deployment. No concentrate wasted from partial discharges. |
Key Features
|
🚗 Fully Mobile — Single Operator, No Civil Works The portable foam fire extinguishing system is mounted on a wheeled steel frame engineered for rapid manual deployment across industrial sites. The balanced weight distribution allows a single operator to manoeuvre through standard doorways, along facility corridors and across outdoor ground to the fire location. No fixed pipework, no civil construction, no electrical connection. For larger sites, tow by vehicle or load onto a flatbed for rapid transport between risk zones. No Fixed Infrastructure Required |
⚡ No Electricity — Works When Site Power Fails Because the bladder tank proportioner operates entirely on water supply pressure, the portable foam system functions independently of site electrical infrastructure — critical in industrial fire scenarios where electrical systems may be compromised, shut down or unsafe to operate. Ready to deploy wherever a fire hose water supply connection is available. No generator, no control panel, no power cable required. Operates 0.6–1.0 MPa Water Supply Only |
|
🎯 Precise Proportioning — Consistent Suppression The venturi proportioner delivers foam concentrate to the water stream at a consistent 3% or 6% ratio across the full rated flow range. Under-proportioned foam lacks the film-forming properties needed to extinguish flammable liquid fires. Over-proportioned foam wastes concentrate. The CA-FIRE bladder tank proportioner maintains accuracy within ±3% of the rated ratio across the 0.6–1.0 MPa working pressure range — reliable suppression performance from first discharge. ±3% Accuracy · 3% or 6% Ratio |
♻️ Reusable Concentrate — Lower Operating Cost After a partial deployment, unused concentrate remaining in the bladder is in full-quality condition — the closed bladder system prevents water from entering the concentrate side of the tank throughout the discharge. This reusability distinguishes the bladder tank from open atmospheric tank proportioners, where any concentrate mixed with water must be disposed of — a significant cost advantage for high-frequency deployment scenarios. Unused Concentrate Retained · No Waste |
Applications
|
Oil Fields & Petroleum Terminals Wellheads, flow lines and tank farm bund areas. Pre-positioned at high-risk locations, deployable to a fire in minutes — before a fixed deluge system activates or before a fire tender arrives. |

Warehouses & Distribution Centres Facilities storing flammable liquids, aerosols and solvents. Distributed through large warehouse areas — provides first-response suppression while fixed sprinkler systems activate. |
Auxiliary to Fixed Foam Systems Backup capability during fixed system maintenance impairments. Directs foam to specific fire locations — tank roof seam failures, pipe flange spray fires — that fixed overhead devices cannot reach. |
Deployment & Installation Guide
Pre-Deployment Checklist
Before deploying the portable foam fire extinguishing system, confirm the following: the foam concentrate type and mixing ratio (3% or 6%) in the bladder matches the discharge device and application requirement; the concentrate level indicator shows a sufficient charge for the anticipated deployment duration; the proportioner, hose connections, discharge device and wheeled frame are free from damage or deterioration; the water supply connection point pressure is within the 0.6–1.0 MPa operating range.
Deployment Procedure
Position the portable foam system upwind and uphill of the fire location where possible, at a safe distance from the fire perimeter. Connect the water supply hose to the system inlet and the selected discharge device to the outlet — ensure all connections are fully tightened. Open the water supply valve progressively (not rapidly, to avoid water hammer in the proportioner). Once stable flow is established, direct the foam stream onto the base of the fire or onto the burning liquid surface as appropriate for the discharge device in use.
Post-Deployment Procedure
After fire suppression is complete, close the water supply valve and disconnect hoses. Check and record the concentrate volume remaining in the bladder. Rinse the proportioner and discharge device with clean water to remove foam residue. Inspect the bladder tank and frame for any damage. Recharge the bladder to the full charge level before returning the unit to standby readiness.
Maintenance Schedule
| Frequency | Task |
|---|---|
| Monthly | Inspect the bladder tank exterior, frame, wheels and handle assembly for corrosion, mechanical damage or deformation. Check all hose connections, valves and proportioner body for leaks or deterioration. Verify the concentrate level indicator shows a full charge. Confirm the unit is stored in its designated location, accessible and unobstructed. |
| Quarterly | Check the bladder condition by comparing concentrate volume indicated against the original fill volume — any unexplained reduction may indicate bladder leakage. Inspect the proportioner inlet and outlet connections for scale, debris or corrosion. Test the water supply connection and verify supply pressure is within the 0.6–1.0 MPa operating range. |
| Annual | Proportioning accuracy test — connect to a calibrated flow measuring arrangement and verify the foam-to-water ratio is within ±3% of the rated mixing ratio at both minimum and maximum rated flow. Inspect the bladder condition through the tank inspection port. Pressure test the tank to 1.5× working pressure and check for leaks. Document all inspection findings in the equipment maintenance log. |
| Every 3–5 years | Preventive bladder replacement regardless of apparent condition, or earlier if inspection reveals cracks, stiffening or chemical attack. CA-FIRE supplies replacement bladders for all PY series models. |
