Products Description
Water Mist Fire Suppression 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
*Displacing oxygen by evaporation
*Attenuating radiant heat by the small droplets themselves
The effectiveness of a water mist system in fire suppression depends on its spray characteristics, which include the droplet size distribution, flux density and spray dynamics, with respect to the fire scenario, such as the shielding of the fuel, fire size and ventilation conditions.
Intermediate pressure: 175psi and 500 psi
High pressure systems: 500psi and up.
Highest pressure System: 1,500psi and up.
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.
Products Advantage
The use of water mist fire suppression, when compared to the use of gaseous agents and traditional sprinkler systems, has revealed advantages such as:
Immediate activation
*High efficiency in the suppression of a wide variety of fires
*Minimized water damage
*Environmentally sound characteristics
*No toxic problems

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