Product Features
- Excellent protective cooling effect: In the event of an external fire, it is particularly effective in providing protective cooling protection for the horizontal, vertical or irregular surfaces of equipment, preventing damage to the equipment structure caused by fire radiation heat.
- Strong fire extinguishing and control capabilities: In some applications, depending on the selection of the designed water spray intensity, the system can be used to control fires or extinguish them.
- Simple and reliable structure: It is composed of a deflector, a diversion cone and a frame, etc. After the pressurized water enters the nozzle, it impacts the deflector through the diversion cone, forming fine atomized water droplets, with reliable performance.
- Diverse materials: The surface materials of the products include bronze, lead-plated, chrome-plated, bronze coated with Teflon, stainless steel, etc., which can meet different environmental and usage requirements.
- Rich specifications: There are various types of nozzles with different flow coefficients and spray angles available for selection to meet different protection areas and fire protection requirements.

Product Parameter
| Parameter Item | Description |
| Nozzle body material | C89830 environmentally friendly brass alloy |
| Atomizing element | Stainless steel swirl plate |
| Sealing system | Double EPDM sealing rings |
| Temperature - sensing element | Glass bulb |
| Rated working pressure | 0.2 - 0.5MPa (2.0 - 5.0bar): Stable pressure is required for medium - speed atomization. Too low pressure will lead to poor atomization, and too high pressure will aggravate wear. |
| Burst pressure | ≥3.5MPa: Safely relieve pressure when over - pressurized to prevent the body from cracking. |
| Operating temperature range | Standard type: 4 - 79℃; High - temperature type (dry system): - 20℃; Chemical explosion - proof type: ≤100℃ (customization required). |
| Installation method | Horizontal or vertical installation (suitable for ceiling/wall), default horizontal installation (nozzle orientation: up/down optional). |
| Connection thread | 1/2 inch (15mm) or 3/4 inch (20mm) taper pipe thread (NPT/G, G1/2, Rc1/2), compatible with galvanized steel pipe and stainless steel pipe. |
| Operating temperature | Basic model: 68℃ (red glass bulb); Optional: 79℃ (yellow), 93℃ (green), 141℃ (blue), 182℃ (purple). |

Application scope
Industrial sites: It can be used for equipment protection in industries such as petrochemicals, power, and metallurgy, such as storage tanks, reactors, transformers, etc.
Commercial premises: Suitable for places with dense populations and concentrated properties such as banks, hotels, and shopping centers.
Other places: It can also be applied to traffic tunnels, underground parking lots, warehouses and other places.
| Type of Premises | Examples | Reason for Adaptation |
| Industrial Plant | Automobile manufacturing workshops, mechanical processing plants | Protect machine tools and electrical cabinets; medium - speed water mist cools equipment while suppressing fire spread |
| Power Facilities | Data center distribution rooms, substation switch cabinets | Accurately cover electrical equipment, avoid water - stain damage, cool down simultaneously to prevent arc re - ignition |
| Chemical/Energy | Flammable liquid storage tank areas, gas turbine rooms | Small atomization particle size; penetrate oil - gas mixtures, suppress steam explosions, cool tank bodies |
| Commercial Complex | Large - scale shopping mall warehouses, cinema projection halls | Protect high - value goods/equipment; medium - speed water mist reduces water damage, balances fire suppression and aesthetics |
