The PL handle-operated foam water dual monitor (PL手柄式水泡沫两用消防炮) is a fixed stainless steel fire monitor that delivers both water and foam solution from the same barrel without any hardware change at the monitor point. An integrated air-aspirating foam generator inside the barrel converts pre-mixed foam solution (supplied by an upstream bladder tank or proportioner) into finished, air-expanded foam stream at the point of discharge. When foam concentrate supply is isolated, the same monitor operates as a standard water cooling monitor. Handle operation allows a single operator to rapidly swing the monitor to any horizontal bearing and adjust vertical elevation from the maximum depression angle of ≤−15° to full elevation of ≥+60°. The handle mechanism provides fast repositioning speed — suited to perimeter monitors that need to be aimed at different points along a tank farm or loading rack during a fire event. Available in three flow ratings: PL8/24 (24 L/s), PL8/32 (32 L/s) and PL8/40 (40 L/s), all at 0.8 MPa rated working pressure.

How the Foam-Water Dual Monitor Works
Water ModeWhen the upstream foam concentrate supply valve is closed, the PL monitor operates as a standard water monitor — receiving pressurised water from the supply main through the monitor base, and discharging it as a high-velocity water jet for tank cooling, exposure protection and structural surface cooling. No setting change is required at the monitor itself. The operator simply closes the foam supply isolation valve to switch from foam to water mode. Foam ModeWhen connected to a foam proportioning system (bladder pressure tank + proportioner, or pump-driven proportioner), the upstream supply delivers pre-mixed foam solution at the correct concentrate-to-water ratio (3% or 6%) to the monitor inlet. Inside the PL barrel, a passive air-aspirating foam generator draws atmospheric air through aspirating orifices and produces finished, air-expanded foam at the point of discharge. The foam stream is discharged directly from the monitor nozzle onto the fire — no external foam maker, foam chamber or branch pipe adapter is needed at the monitor position. Key point — what the PL monitor requires upstream: The PL monitor does not mix water and foam concentrate — this mixing is done upstream by the proportioning system. The monitor receives already-mixed foam solution and adds the air-aspiration step at the nozzle. A foam bladder tank or other proportioner is always required to supply the pre-mixed solution to any PL monitor installation. CA-FIRE supplies the complete system — foam bladder tanks → |

Key Features
|
💧 Water + Foam Single monitor delivers both water cooling and foam suppression from the same fixed position — no hardware change at the monitor. Integrated air-aspirating foam generator produces finished foam at the nozzle. Compatible with AFFF 3%/6% and AR-AFFF 3%/6% concentrate systems. |
🎯 Handle — Fast Direct handle operation allows a single operator to swing horizontal bearing and adjust elevation quickly — no mechanical resistance from a gearbox. Essential for perimeter monitors that need to shift aim between multiple tank positions during an emergency response. |
⬆️ ≥+60° Elevation Full elevation to ≥+60° allows foam attack on fixed-roof tanks at ground level, reaching the tank top and rim seal area. Depression to ≤−15° allows monitor coverage into bunded areas, sumps and low-level spill containment areas below the monitor installation plane. |
🔩 Stainless Steel Full stainless steel body construction for installations in coastal, chemical, petrochemical and high-humidity environments where carbon steel would require intensive maintenance. Compatible with the corrosive constituents of AFFF and AR-AFFF foam concentrates over long service life. |
Applications
|
Petrochemical Storage Tank Farms Fixed PL monitors on tank farm perimeters for simultaneous foam suppression on burning tanks and water cooling on adjacent tanks. GB 50151 requires fixed foam monitors above defined tank capacities. The PL monitor provides both foam attack and exposure protection from a single monitor position — the standard configuration for tank farm fixed monitor systems. Typical spec: PL8/40 (max-flow handle model) |
Aircraft Hangars — AFFF Fixed Monitor System PL monitors are specified in aircraft hangar fixed foam monitor systems per ICAO Doc 9137 and CAA requirements. The integrated foam generator produces AFFF or AR-AFFF foam stream at the required foam application rate (FAR) for the aircraft category. Handle models are appropriate for smaller hangar bays where monitor coverage requirements are met by PL8/24–PL8/40 flow rates. For large-area hangar coverage at PL8/40 flow, confirm monitor spacing per GB 50151 at design stage. Typical spec: PL8/40 · AR-AFFF 3%/6% |
Chemical Plants & Flammable Liquid Processing Fixed monitors at chemical reactor areas, loading racks, solvent storage and process areas where flammable liquid release and ignition is a credible scenario. PL monitors provide both foam suppression of pool fires and water cooling of process equipment and structural steelwork. The stainless body resists chemical attack from aggressive process atmospheres and foam concentrate. Typical spec: PL8/32 or PL8/40 |
|
Port & Terminal Fuel Facilities Fuel terminal berths, marine fuel jetties and bunkering facilities with flammable liquid storage. Handle models allow pier-edge monitors to be quickly redirected to different vessel positions or spill areas. For maximum reach at port facilities handling large vessels, also consider the PS10/80W water monitor or the RCFM electric series for remote operation from a safe control point. Typical spec: PL8/32 · AFFF 3% |
LPG Cylinder Filling & Storage Facilities LPG storage, bottling plants and bulk LPG rail/road loading facilities require monitors capable of both foam application on liquid spill fires and water cooling of cylinders and vessels under fire exposure (BLEVE risk mitigation). The handle mechanism allows rapid reorientation between cooling and suppression tasks during an incident. Typical spec: PL8/24 or PL8/32 |

PL Handle vs PL Turbine-Worm — Which Model?
|
✅ PL Handle-Operated (This Page) PL8/24 · PL8/32 · PL8/40 · 0.8 MPa · 24–40 L/s Choose the handle-operated series when rapid repositioning speed is more important than precise aim retention at full flow. The direct handle mechanism is mechanically simple, requires no gearbox and allows a single operator to rapidly swing the monitor to any bearing during a developing fire event. The 40 L/s maximum flow at 0.8 MPa is sufficient for most perimeter monitor applications on tank farms compliant with GB 50151. ✓ Rapid traverse — fast repositioning between fire targets |
PL Turbine-Worm (Higher Flow) PL10/48 · PL10/64 · 1.0 MPa · 48–64 L/s → View → Choose the turbine-worm series when the system design requires flow rates above 40 L/s, or when nozzle reaction force at the specified flow rate exceeds what a handle mechanism can comfortably hold in position. At 48–64 L/s and 1.0 MPa, the worm gear provides self-locking aim retention and mechanical advantage for stable high-flow operation. Specified for large tank farm fixed monitor systems and major aircraft hangars where GB 50151 or ICAO requires higher foam application rates than handle models can deliver. ✓ Flow 48–64 L/s for large-area coverage requirements |
Installation Notes
The PL handle-operated monitor is designed for fixed installation on a fire monitor base (消防炮座, PZ series) or a flanged riser pipe connected to the fire water and foam solution supply main. Key installation considerations:
| Item | Requirement / Guidance |
|---|---|
| Supply connection | Flange connection (法兰连接) to monitor base or riser. Connect to the foam-water combined supply main (downstream of the foam proportioning system). Supply pressure at the monitor inlet must be at rated 0.8 MPa at design flow. Confirm supply system hydraulics before specifying model (PL8/24, PL8/32 or PL8/40). |
| Monitor base | Install on CA-FIRE PZ series fire monitor base (消防炮座) for vehicle impact (anti-collision breakaway) protection, frost-protected auto-drain and supply isolation. Specify PZ100-1.6 or PZ100-1.6C (gear-driven) for DN100 supply inlet. The monitor base connects directly to the buried supply main — no separate above-grade isolation valve is needed. See fire monitor base page for full specification. |
| Foam supply system | A foam proportioning system must be installed upstream. CA-FIRE bladder pressure tanks (立式泡沫压力罐 / 卧式泡沫压力罐) are the standard supply system for fixed monitor installations — they require no external power and activate automatically on supply main pressurisation. Confirm foam concentrate type (AFFF 3%/6% or AR-AFFF 3%/6%) and system demand volume with CA-FIRE at enquiry. See foam bladder tank page. |
| Monitor elevation / placement | Install with clear sight lines to all protected areas within the monitor’s coverage arc. Elevation angle ≥+60° is the rated maximum — do not obstruct the monitor’s rotation sweep with overhead structures within the operating arc. Installation height should be calculated to ensure the foam stream reaches the rim seal area of the tallest tank within the coverage zone at the specified flow rate and elevation angle. |
| Maintenance | Quarterly: exercise handle through full horizontal and vertical range of motion. Check for corrosion, seal condition, and freedom of movement. Annual: flush monitor barrel with clean water to remove accumulated foam concentrate residue. Inspect nozzle tip, foam generator orifices and seal faces. Full performance test (flow, elevation, horizontal sweep) per GB 50151 maintenance requirements at intervals specified in the system maintenance schedule. |
