Manual Fixed Fire Water Cannons

1. Large-Space Buildings: Filling Hydrant Coverage Gaps

In logistics parks and exhibition centers with ceilings >8 meters, standard hydrant nozzles only reach 10–15 meters, failing to cover cross-area fire points. The 50–60 meter range of the water cannon enables "single-point coverage of multiple zones," with 360° rotation allowing one cannon to protect an entire fire compartment, reducing equipment redundancy.

Professional Knowledge Extension: The heat release rate (HRR) in large-space fires can be 10 times higher than in ordinary buildings. The cannon's high-flow jet rapidly reduces fire temperature, aligning with the tactical principle of "containment first, rescue prioritized."

2. Chemical Parks: Core Equipment for Explosion-Proof Cooling

In chemical tank farms, direct jet attacks on flammable liquid fires can cause splashing and spread. The cannon's spray mode creates a mist layer ≥0.5 meters thick, cooling tank surfaces at ≥10°C/min to prevent explosions and diluting surrounding combustible gases below their lower explosive limit (LEL).

Professional Knowledge Extension: Per Code for Design of Fire Protection in Petrochemical Enterprises (GB 50160-2008), water cannons in tank farms must be spaced ≤60 meters apart with a protection radius ≥50 meters to ensure full coverage.

3. Outdoor Freeze Protection: Winter Network Defense in Northern China

In northern China's severe cold regions, frozen outdoor fire equipment is a leading winter failure. This cannon features a built-in DN25 drain valve to empty residual water before winter, and with a self-regulating heating trace (≥100W/m), it operates reliably at -20°C, avoiding freeze-related failure.

Professional Knowledge Extension: Winter fire safety in northern China centers on "freeze protection and unobstructed flow." The cannon's drain valve must be linked with network drain valves to fully empty residual water-a process mandated in GB 50974's winter maintenance guidelines.
