Foam Bladder Tank Systems
Complete Foam Bladder Tank Range — DN80 to DN250, 4 to 360 L/s
CA-FIRE manufactures a complete range of foam bladder tank systems for fixed and mobile foam fire suppression. All models operate on a fully hydraulic proportioning principle — no electricity required — delivering ±0.3% mixing accuracy at 3% or 6% ratio across flow rates from 4 L/s to 360 L/s and tank volumes from 0.5 m³ to 13.0 m³.
Compatible with AFFF, AR-AFFF and protein foam concentrates. Compliant with NFPA 11 (Low-, Medium- and High-Expansion Foam) and NFPA 16 (Closed-Head Foam-Water Sprinkler). GB / ISO 9001 / CE certified. Supplied to petrochemical, aviation, marine and industrial projects in 50+ countries.
All units are supplied as complete, ready-to-install systems — pressure vessel, internal rubber bladder, proportioner assembly, isolation valves, pressure gauges, safety relief valve, level indicator and full system documentation. See our technical download centre for datasheets and installation manuals.

PHYM Series · Horizontal · Low Profile
Horizontal Foam Bladder Tank
Low-profile horizontal configuration for underground pump rooms, basements,
shipboard spaces and low-ceiling buildings. Widest flow range in the CA-FIRE line:
4–360 L/s. Saddle-mounted — no height restriction above tank crown.

PHY Series · Vertical · Compact Footprint
Vertical Foam Bladder Tank
Upright configuration with minimal floor footprint — preferred for above-ground fire pump
rooms where ceiling height is available but floor space is constrained. Six flow models:
PHY 8 to PHY 64. Uses less than half the floor area of equivalent horizontal tanks.

See How a Foam Bladder Tank System Works
This demonstration shows the PHYM/PHY series foam bladder tank in operation — from system pressurisation through proportioner activation to confirmed foam discharge.
- Hydraulic proportioning — zero electricity required
- Internal rubber bladder isolates foam from water supply
- ±0.3% mixing accuracy at 3% or 6% ratio
- Full factory hydrostatic test at 1.5 MPa before despatch
- Compatible with AFFF, AR-AFFF & protein foam concentrate
Which Foam Bladder Tank Do You Need? — Selection Guide
| Your Situation | Specify This Product | Key Reason |
|---|---|---|
| Underground pump room, basement, shipboard, or low-ceiling building |
Horizontal Foam Bladder Tank PHYM Series · 4–360 L/s View Horizontal Tank → |
Horizontal orientation minimises installed height. Saddle-mounted on foundation — no structural clearance above tank crown. Widest flow range: 4–360 L/s. |
| Above-ground fire pump room, plant room or equipment building with limited floor space |
Vertical Foam Bladder Tank PHY Series · 8–120 L/s View Vertical Tank → |
Vertical orientation trades floor area for height — in some sizes less than half the floor footprint of an equivalent horizontal tank. Preferred where floor space is shared with pumps, switchgear and other equipment. |
| No fixed pipework — first response, temporary protection or mobile supplementary suppression |
Portable Foam Fire Extinguishing System Mobile Unit · 4–8 L/s View Portable System → |
Self-contained — proportioner, foam tank, hose and nozzle on a single wheeled or skid frame. No civil works required. Deployable to any hazard location within minutes. |
| High flow rate system >120 L/s (large petrochemical tank farm or major aircraft hangar) |
Horizontal Foam Bladder Tank PHYM Series · up to 360 L/s View Horizontal Tank → |
The PHYM horizontal series reaches 360 L/s — more than 3× the maximum flow of the vertical range. Only option for peak demand on large tank farm and major hangar suppression systems. |
