Wet Type Kitchen Equipment Fire Suppression Device with Automatic Manual Mechanical Emergency Control and 12L×2 Cylinder Volume for Commercial Kitchen

Commercial kitchen equipment fire suppression devices fall into two categories: dry type and wet type. Dry type devices primarily use super-fine dry powder as the extinguishing agent, while wet type devices are mainly filled with a water-based extinguishing agent.

Our company adopts the wet type fire suppression device, which relies on a specific quantity of extinguishing agent to extinguish a fire. It works primarily through contact with the surface of high-temperature edible oil to produce a saponification reaction. Simultaneously, it absorbs a large amount of heat, generates a foam covering layer, isolates oxygen, and carries out firefighting. To prevent reignition of the oil pot, the device reduces the oil temperature to below 363°C by spraying cooling water. This type of fire suppression device offers the advantages of high fire-extinguishing efficiency and an easy-to-clean site after fire extinguishing.

The kitchen equipment fire suppression device is mainly used at the following sites:

The complete kitchen equipment fire suppression device consists of the following components:

• Extinguishing cylinder group (steel cylinder, siphon extinguishing agent)
• Linkage valve
• Pipeline (discharge line of extinguishing agent, cooling line, gas cut-off line)
• Nozzle (special atomizing nozzle)
• Valves (gas shut-off valve, liquid check flow valve, and water flow valve)
• Fire detecting part (fusible metal temperature sensor)
• Control panel

The complete composition of the whole device is shown below:

Complete composition of the kitchen equipment fire suppression device

1. The automatic fire suppression device is equipped with three starting functions: automatic control, manual control, and mechanical emergency operation control. It can monitor for fire 24 hours a day.
2. The automatic fire suppression device is equipped with a delay starting function to effectively avoid accidental spraying.
3. The nitrogen storage container is equipped with a pressure indicator, which effectively monitors for nitrogen leakage.
4. The nozzle is composed of a scroll nozzle core, filter net, and nozzle cap — all made of 304 stainless steel for anti-corrosion and anti-adhesion performance.
5. Mechanical and electric control are combined with transmission, making movement more reliable and sensitive. This effectively prevents grease from sticking to the wire rope.
6. After the extinguishing agent has finished spraying, the water linkage valve begins to work, continuing to cool by spraying and preventing reignition.
7. It can rapidly cut off the fuel gas valve (optional).
8. It can send an action signal to the firefighting control center.
9. Agent features: colorless, tasteless, non-toxic, pollution-free, easy to clean, and environmentally friendly.
