Fire Monitor — Water & Foam-Water Cannon Series

PL Series · Foam-Water Dual

Handle-Operated Foam-Water Monitor

Stainless steel foam-water dual monitor with handle operation. Delivers water or pre-mixed foam solution (AFFF/AR-AFFF) through an integrated air-aspirating foam generator. Continuously adjustable horizontal and vertical aim with full ≥+60° elevation. For tank farm perimeter protection and aircraft hangar fixed monitor systems where both water cooling and foam suppression are required from a single monitor point.

PL Series · Foam-Water Dual

Turbine-Worm Foam-Water Monitor

High-flow version of the PL foam-water monitor series, with turbine-worm geared traverse and elevation for precise aim positioning under high-pressure, high-flow conditions. The worm gear mechanism maintains aim position under nozzle reaction force at full flow — essential for large fixed monitors in refineries and LNG terminals where flow rates exceed 48 L/s. Same integrated foam-generation capability as the handle series.

PS Series · Water Monitor

Handle-Operated Water Monitor

Stainless steel fixed water monitor with handle operation and continuously variable straight-stream to full-cone fog pattern nozzle — switchable steplessly without tools during operation. The handle traverse allows rapid repositioning by a single operator. Reach ≥65 m at rated flow. Available in standard stainless steel body and lightweight aluminium alloy (-L) body versions for installations where reduced dead load is a structural requirement.

PS Series · Water Monitor

Turbine-Worm Water Monitor

High-flow stainless steel water monitor with turbine-worm geared traverse and elevation. At 60–80 L/s and 1.0 MPa, nozzle reaction forces exceed what a handle mechanism can hold in position — the worm gear locks aim precisely under full flow conditions. Straight-stream reach ≥75–85 m. The PS10/80W is the highest-flow model in the range, the standard specification for large tank farm fixed monitor systems and major port facilities requiring maximum throw distance.

PS Series · Aluminium · Max Flow

PS10-80W-L Portable Water Monitor

The PS10-80W-L is the aluminium alloy maximum-flow monitor in the range — delivering 80 L/s at 1.0 MPa with a straight-stream reach of ≥85 m, in a lighter-weight body that can be relocated between fixed monitor base positions. The red-finished aluminium construction provides clear visual identification in complex facility layouts. Handle-operated traverse and elevation. Stepless straight-stream to fog pattern nozzle. The standard maximum-flow choice for temporary deployment and facilities specifying aluminium alloy throughout for weight reasons.

Fire Monitor Base · Supply Station

Gear-Driven Anti-Collision Pressure-Regulating Monitor Base

The fire monitor base (消防炮座) is the below-grade supply station that connects the buried fire main to the above-ground monitor. It integrates on/off valve, anti-collision breakaway protection, frost-protection auto-drain, pressure regulation and supply isolation in a single flanged assembly — replacing four to six separate components in a traditional riser assembly. The gear-driven (齿轮传动) variant adds worm-gear operated valve actuation for installations requiring mechanical advantage. Available in standard, gear-driven and multi-function variants across DN100 and DN150 inlet sizes.

PL Series — Foam-Water Dual Monitor

水、泡沫两用型消防炮 · PL8/24 to PL10/64

The PL series is a combined water cooling and foam suppression system in a single monitor body. A built-in air-aspirating foam generator is integrated into the barrel — when connected to a foam proportioning system supply, the monitor produces finished foam solution internally and discharges it directly as an air-aspirated foam stream. No external foam maker or branch pipe is required at the monitor point itself.

When the foam supply is not in use, the PL monitor operates as a standard water monitor for cooling and exposure protection. This dual capability makes it the correct choice for facilities where both Class B fire suppression (flammable liquid fires) and simultaneous water cooling of adjacent structures are required from the same monitor position.

Models: PL8/24 · PL8/32 · PL8/40 (handle, 0.8 MPa) · PL10/48 · PL10/64 (turbine-worm, 1.0 MPa)

PS Series — Water Monitor

消防水炮 · PS8/20W-L to PS10/80W

The PS series is a fixed water monitor optimised for maximum flow, reach and pattern flexibility. A key feature of the PS nozzle is stepless straight-stream to full-cone fog pattern switching without tools — the operator can transition from a high-reach solid stream for distant fire attack to a protective fog curtain for chemical vapour control or close-range cooling without any nozzle change or interruption to flow.

Available in stainless steel (standard) and aluminium alloy (-L suffix) body versions. The stainless range covers 20–80 L/s. The turbine-worm variants (PS10/50W to PS10/80W) are the highest-flow models with worm-gear aim locking for stable high-pressure operation. At 80 L/s and 1.0 MPa, the PS10/80W delivers a straight-stream reach of ≥85 m — the longest in the range.

Stainless models: PS8/30W · PS8/40W · PS10/50W-B · PS10/50W · PS10/60W · PS10/80W
Aluminium models: PS8/20W-L · PS8/30W-L · PS8/40W-L · PS10/50W-L · PS10/60W-L · PS10/80W-L

💧 Integrated Foam Generation — PL Series

The PL series incorporates an air-aspirating foam generator directly into the monitor barrel body. When connected to a foam proportioning system supply (bladder tank, pump-based proportioner or inline eductor), the monitor draws air through the aspirating orifices and produces finished, air-expanded foam solution internally — discharging it as a full foam stream. No external foam maker, foam chamber or branch pipe adapter is needed at the monitor point. The foam generation mechanism is passive (no moving parts) and functions at any flow rate within the rated range. The same monitor operates as a standard water monitor when foam concentrate supply is isolated — allowing the same fixed installation to deliver both water cooling and foam suppression without any hardware change at the monitor itself.

🎯 Stepless Pattern Control — PS Series

The PS nozzle provides continuous, stepless transition between solid straight stream and full-cone spray pattern by rotating the nozzle tip during operation — without interrupting flow, changing nozzle tips or using tools. In straight-stream mode, the PS10/80W delivers a coherent jet to ≥85 m for long-range fire attack on distant tanks, vessels or structures. In fog mode, the full-cone pattern provides close-range personnel protection, chemical vapour suppression and surface cooling at dramatically higher surface coverage per L/s than a solid stream. A single monitor can transition from long-range attack to short-range protective fog in seconds, adapting to changing incident conditions in real time. This capability replaces separate straight-stream and fog nozzles that would otherwise require manual swapping under operating conditions.

⚙️ Worm-Gear Aim Lock — Turbine-Worm Models

At high flow rates (≥48 L/s for PL, ≥50 L/s for PS), nozzle reaction forces exceed what a direct handle mechanism can reliably hold in position — the monitor will drift from its aimed direction under flow if only a friction or detent lock is used. The turbine-worm gearbox in the PL10/48–PL10/64 and PS10/50W–PS10/80W models converts the high reaction force into a self-locking worm drive that maintains aim position indefinitely under full flow without operator effort. The handwheel drive also provides significant mechanical advantage for precise angular positioning in strong cross-wind conditions, where direct handle monitors may oscillate. Worm gear mechanisms are irreversible — the position is held by the gear geometry itself, not by a separate lock, so position is maintained even if the operator releases the handwheel.

🛡️ Anti-Collision Breakaway Base — Monitor Base Series

Fixed fire monitors in tank farms, refinery roads and port facilities are at significant risk of vehicle impact. The anti-collision breakaway design of the PZ monitor base series allows the above-grade riser and monitor assembly to shear off cleanly at a designed break point if struck by a vehicle — without damaging the below-grade main body or supply pipework, and without causing an uncontrolled water release. The below-grade body automatically seals at the break point by the same spring-loaded auto-drain mechanism used for frost protection. This means a vehicle collision results in a clean, self-sealed stub rather than a ruptured supply main flooding the facility. The sheared above-grade assembly is replaced at the designed break coupling — restoring full monitor function without excavation or pipework repair. The gear-driven variant (PZ-1.6C) adds worm-gear valve actuation for remote or low-force operation in high-pressure applications.
