Core advantages
Robust and reliable, with intelligent protection
304L stainless steel one-piece molding
Compared with ordinary 304 stainless steel, 304L has a lower carbon content and extremely strong resistance to intergranular corrosion. It can resist the corrosion of fire-fighting foam, seawater and chemical agents for a long time, is not afraid of acidic and alkaline environments, and its service life is extended by more than 50%.
Automatic monitoring nozzle system
It is equipped with a high-sensitivity sensor to monitor the injection status and Angle in real time and automatically feed back to the control terminal. Alarm immediately in case of unexpected deviation or blockage to ensure the continuous effectiveness of fire-fighting operations.
Ultra-wide-angle coverage, no blind spot protection
Vertical travel of 135° (from -45° dive to +90° elevation Angle), easily handling ground flowing fires or high-altitude fire points. With a horizontal rotation of 350°, it leaves only a 10° safety blind zone, achieving nearly panoramic coverage.
Dual-mode injection, one-click switching
Electronic control for quick switching:
✅ Direct injection mode - strong impact force, extinguishing concentrated fire sources, cooling equipment
✅ Mist spray mode - large coverage area, blocking radiant heat and diluting chemical vapors

FAQ
Q: There are 3000, 3600, and 4800 LPM traffic options available. How should we decide? Is it true that the greater the traffic, the better?
A: Not at all. Selecting the flow rate requires a scientific match with the capacity of your fire pump and the supply of your pipeline. We suggest:
- 3000 LPM: Suitable for factory renovation projects where the pressure of the existing water supply network is relatively low (such as 0.8-1.0MPa).
- 3600 LPM: It is the "gold standard" for most new petrochemical projects, balancing fire extinguishing efficiency with equipment costs.
- 4800 LPM: Specifically designed for large oil tanks and liquefied natural gas terminals, it requires the matching of high-power fire pumps and thick-diameter main pipes.
Q: The vertical range is from -45° to +90°. What's the use of this -45° downward?
A: This design is aimed at the key scenarios in real fires:
- Extinguishing ground flowing fires: After a petrochemical material leakage catches fire, it often spreads along the ground. A -45° depression Angle can precisely cover the fuel surface with foam.
- Cooling adjacent tanks: When adjacent storage tanks are threatened by thermal radiation, downward spraying can continuously cool the weak areas beneath them.
- Clearing obstacles: Strong water flow can wash away scattered fire spots or obstacles on the fire extinguishing passage.
Q: How are direct spray and mist spray modes specifically used in actual fire extinguishing?
A: This is a tactical-level switch:
- Direct spray (direct current) : Like "fire-fighting water arrows", it is used for strong attacks and close combat. For instance, concentrating water flow to cut the base of the flame or conducting targeted and powerful cooling on the high-temperature tank wall.
- Mist spray (flowering) : Forms a water mist barrier for defense and coverage. For instance, an insulating screen can be formed between rescue workers and the fire scene, or the volatile toxic gases can be diluted and dispersed. It can be switched with one click through the remote control to achieve flexible tactical combinations.
