High-pressure water mist fire suppression system (closed type)
A fine-water mist fire suppression system consists of a water source, water supply equipment, piping, valve assemblies, filters, and fine-water mist nozzles. The mist droplets in fine-water mist do not alter the chemical properties of water; rather, they merely change its physical state, yet achieve fire-extinguishing effects that surpass those of conventional water streams. Under a certain pressure, a fine-water mist fire suppression system uses specialized fine-water mist nozzles to spray water mist onto the target object, rapidly extinguishing the fire. It is a fire suppression device that is "highly efficient, safe, economical, and environmentally friendly."

Overview
A fine-water mist fire suppression system consists of a water source, water supply equipment, piping, valve assemblies, filters, and fine-water mist nozzles. The mist droplets in fine-water mist do not alter the chemical properties of water; rather, they merely change its physical state, yet achieve fire-extinguishing performance that surpasses that of conventional water streams. A fine-water mist fire suppression system is a fire-extinguishing device that sprays water mist onto the target object under a certain pressure through specialized fine-water mist nozzles, enabling rapid fire suppression. It is a fire-extinguishing system that is "highly efficient, safe, economical, and environmentally friendly."
Working principle
Through the combined effects of fine water mist—including cooling, asphyxiation, dilution, emulsification, isolation, and wetting—the combustion is prevented from sustaining itself, thereby achieving the purpose of fire suppression. Among these effects, cooling and asphyxiation play the decisive roles.
