Water Mist System

Tech US Water Mist Fire Suppression System employs fine water droplets, typically less than 1 mm in diameter, to control and extinguish fires. These droplets rapidly cool the flame, absorb heat efficiently, and displace oxygen. This system effectively suppresses fires while minimizing water damage and ensuring rapid fire control.

What is Water Mist Fire Suppression System?

Fire sprinkler systems and water mist systems, while similar in using water for fire suppression, differ primarily in droplet size. NFPA 750 defines water mist as a fine spray where 99% of droplets are less than 1000 microns in diameter. Water mist systems are classified based on the pressure of their distribution piping: low-pressure systems operate at 12.1 bar (175 psi) or below, intermediate-pressure systems range from 12.1 to 34.5 bar (175 to 500 psi), and high-pressure systems exceed 34.5 bar (500 psi). These categories reflect differences in mist dispersion and effectiveness in various fire scenarios.

System Operation Explanation

Fire sprinkler systems work by soaking fires and nearby fuel sources with water. In contrast, water mist systems use fine nozzles to spray tiny water droplets that form a mist. This mist cools the fire, absorbs heat, and displaces oxygen. The small droplets evaporate into steam, which absorbs heat faster and limits the fire's oxygen supply. Additionally, the mist prevents radiant heat from spreading to nearby combustibles, reducing the risk of fire spread and damage while minimizing water damage to nearby equipment and machinery.
