Nozzle Type( Open Type & Closed Type)
1. Open Type Nozzle


The open water mist nozzle is made of austenitic stainlesssteel and consists of a shell, a nozzle, etc. Its core component is a plurality of centrifugal nozzles installed on the conical surface of the shell. The atomization mechanism is to utilize the rotating liquid produced by the swirling parts in the nozzle to accelerate and eject the hollow diffusion cone-shaped liquid film through the outlet channel, and use the speed difference between the liquid and the outside air to break up and atomize.
While on stand-by, our system boasts dry piping for maximum efficiency. Activation can be achieved manually or through the sensors that detect heat, smoke, or flames - tailored to your specific needs. Our nozzles are thoughtfully grouped in sections, so upon activation, all nozzles within the selected section will be released for optimal fire suppression.
1. Closed Type Nozzle

The closed water mist nozzle is made of austenitic stainless steel and consists of a shell, a nozzle, a temperature-sensitive glass ball, etc. Its core component is a plurality of centrifugal nozzles installed on the conical surface of the shell. The atomization mechanism is to utilize the rotating liquid produced by the swirling parts in the nozzle to accelerate and eject the hollow diffusion cone-shaped liquid film through the outlet channel, and use the speed difference between the liquid and the outside air to break up and atomize.
While in standby mode, our system maintains a pipe pressure of approximately 12 bar. Once the temperature surpasses 57°C, the heat-sensitive glass bulbs integrated into the nozzle heads will begin to melt. As a result, the high-pressure pump will be automatically activated, forcing water through high-pressure nozzles (60 or 100 bar, depending on nozzle type) to produce a fine mist. Only those nozzles with melted bulbs will activate, ensuring that only the affected area is actively sprayed.

Working Diagram
* Fire Detection: Sensors trigger the system upon detecting fire.
* Pump Activation: The pump pressurizes water, pushing it through nozzles.
* Mist Generation: Nozzles atomize water into a fine mist, creating a cooling effect through evaporation and displacing oxygen with steam.
The working principles of a pump-pressurized high-pressure water mist fire system revolve around atomizing water into ultra-fine droplets and leveraging their unique properties to suppress fires through rapid cooling, oxygen displacement, and heat radiation blocking.



Product Application
The fine water mist fire extinguishing system is widely used in various scenarios, including but not limited to:
Computer Rooms, Data Centers, Archives, Libraries, Generator, Transformer, Electric Room, Engery Storage, Container(Battery Room), Medical Device Room, Others Important Equipment Storage Places.
These places often store high-value equipment and materials, and once a fire occurs, the consequences can be unimaginable. Therefore, using a fine water mist fire extinguishing system can quickly extinguish the fire source in the early stages of a fire and protect important assets.High efficiency in the suppression of a wide variety of fires
* Data centers and IDC facilities
* Server rooms and UPS rooms
* Electrical switchgear rooms
* Power control rooms
* Telecommunication facilities
* Industrial automation systems
* Petrochemical control rooms
* Archives, libraries and laboratories
* Power plants, offshore power platforms, control rooms and substations, high and low voltage power distribution rooms/control rooms, hospitals, energy storage cabinets, high-speed rail stations/subway stations.
