TRANSCRIPT
X-MIST® SYSTEM extinguishes or controls fires by cooling, oxygen displacement by water vapor and radiant heat attenuation. The exceptional cooling effect of water mist is a result of the division of water into very fine droplets, which increase the total surface area available to absorb heat and maximizes the evaporation rate of the water.

Local Water Mist Fire Fighting System for Machinery Space
Applied Rule & Regulation Ⅱ
Major Component
Main Control Panel
Fire Monitor (Repeat Panel)
Receive fire signal from alarm control panel.Operate pump/motor and section valve.Check an error of system.
Receive fire data from main control panel. Display the state of fire at each section.
Alarm Control Panel Smoke / Flame Detector
Receive fire data from detector consisted loop.
Addressable type
The panel is installed at each section. Manual release of water mist.
Local Control Panel
Supply water to each protected area. Composed of pump/motor, MOV valve, motor starter panel.
Extinguishment
Burning of fuel before water spray.
Water spray through nozzle after detection of flame & smoke.
The flame reduction results by cooling, oxygen depletion and wetting of the fuel.
The fire is completely extinguished.
Ignition Suppression
Pump Unit (MOV type)
