Product Description

Product Description

NFPA750 Pump Type High Pressure Water Mist Fire System

A water mist system is a fire protection system which uses very fine water sprays (i.e. water mist). The small water droplets allow the water mist to control, suppress or extinguish fires by: Cooling both the flame and surrounding gases by evaporation---Absorb Heat&Cooling Displacing oxygen by evaporation---Isolate Oxygen Attenuating radiant heat by the small droplets themselves---Isolate Heat

The effectiveness of a water mist system in fire suppression depends on its spray characteristics, which include the droplet size distribution, spray density and spray dynamics, with respect to the fire scenario, such as the shielding of the fuel, fire size and ventilation conditions.

So really high pressure system, specialized tubing or piping that's used for that. Now, there are differences between water mist systems and the droplet sizes that they produce, so typically the smaller the water droplet size the better it is at extinguishing a hot fire. Larger droplets can work faster on lower temperature fires, but they all work for the systems that they're approved for or listed for.

Importance of Water Mist Suppression Systems
Water mist suppression systems play a critical role in fire protection for diverse environments by:
1.Versatile Application: Suitable for a wide range of special hazards including marine applications, valuable assets, property, and industrial hazards. Water Mist provides comprehensive and effective fire protection.
2. Minimal Water Usage: Utilizing minimal clean water, reducing the risk of water damage to equipment and property, and minimizing water run-off during fire incidents.
3. Rapid Suppression: Swiftly extinguishing fires, minimizing damage and ensuring the safety of occupants.

How Water Mist Suppression Systems Work:
Water mist suppression systems operate by releasing a fine mist of water droplets, which rapidly evaporate and absorb heat. The oxygen at the source of the fire is also displaced by the quick evaporation of the water droplets causing a depletion of oxygen effectively suppressing the fire.  

Product Advantages

Benefits of Water Mist Suppression Systems: 
 1. Speed of Installation: Water mist systems use small tubing or pipe compared to conventional water sprinkler systems, making it possible to conceal the pipe and reducing installation time.
 2. Reduces Post Water Damage: Water Mist Systems use a fraction of the amount of water conventional water sprinkler systems use which minimizes any water damage and reduces water run-off.
3. Environmentally Friendly : Utilizing minimal water and  reducing the need for cleanup ensuring minimal environmental impact.
4. Cost Effective : Low cost and expense for small volumes of potable water. 

 

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.

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.

2. 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.

Product Application
