Horizontal Foam Bladder Tank — PHYM Series Low-Profile Pressure Proportioning Device
Horizontal Foam Bladder Tank — Key Features
Low-Profile Horizontal Configuration — Installs Where Vertical Tanks Cannot
The defining installation advantage of the horizontal foam bladder tank
is its low profile. Orienting the pressure vessel horizontally reduces installed height
significantly — making it the only practical foam bladder tank configuration for
underground pump rooms, basement plant rooms, shipboard
suppression systems, and any installation where ceiling height prevents
a vertical tank.
The horizontal orientation also distributes tank weight across a larger floor area,
reducing foundation load concentration and simplifying structural support requirements.
Fits Low-Ceiling & Underground Spaces
±0.3% Mixing Accuracy — Across Full 4–360 L/s Flow Range
The PHYM horizontal foam bladder tank maintains foam concentrate
delivery accuracy within ±0.3% of the rated 3% or 6% mixing ratio
across the full 4–360 L/s operating flow range — passively, without electronic
controls or operator adjustment.
Under-concentration reduces foam stability and fire knockdown. Over-concentration
wastes expensive concentrate. The bladder’s hydraulic balance mechanism holds the ratio
stable across the complete working pressure range of 0.6–1.2 MPa.
±0.3% — Exceeds NFPA 11 Requirements
Bladder Isolation — Concentrate Preserved, Reusable After Partial Discharge
The rubber bladder inside the horizontal foam bladder tank physically
separates foam concentrate from the pressurised water supply at all times during storage
and operation. Water cannot enter the concentrate side — the mechanism by which foam
concentrate degrades in open-tank systems.
After a partial discharge, unused concentrate remains in the bladder in full-quality
condition — ready for reuse at the next activation without replacement.
Shelf life: typically 10–25 years depending on concentrate type.

Fully Customisable — Tank Volume, Pipe Diameter and Flow Rate to Order
CA-FIRE supplies the PHYM horizontal foam bladder tank configured
precisely to the hydraulic model of each suppression system. Tank volume (0.5–13.0 m³),
main pipe diameter (DN80–DN250), and proportioner flow capacity (4–360 L/s) are all
adjustable — matching required discharge duration and peak flow exactly.
No forced over-specification to the nearest catalogue size. Free hydraulic sizing
support provided by CA-FIRE’s engineering team for every project — NFPA 11,
NFPA 16 or GB standard.

Horizontal vs. Vertical Foam Bladder Tank — Which to Specify?
Both configurations deliver identical proportioning performance (±0.3%). The decision is driven entirely by the physical dimensions of the installation space:
| Parameter | Horizontal Bladder Tank (PHYM) | Vertical Bladder Tank (PHY) |
|---|---|---|
| Installed height | ✓ Low — fits restricted headroom | Higher — requires ceiling clearance |
| Floor footprint | Larger — longer saddle-mounted footprint | ✓ Compact — smaller floor area |
| Underground / basement rooms | ✓ Preferred — low profile fits | — Less suitable |
| Shipboard installation | ✓ Standard choice for vessels | — Space constraints usually prohibit |
| Above-ground pump rooms | Suitable | ✓ Preferred — maximises floor space |
| Maximum flow rate | 4–360 L/s (widest range) | 8–120 L/s |
| Tank volume range | 0.5–13.0 m³ | 0.5–13.0 m³ |
| Proportioning accuracy | ±0.3% | ±0.3% |
| Mixing ratio | 3% or 6% | 3% or 6% |
