1. How does water mist system work?
  2. 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.
  3. What is working pressure of the mist system?
  4. The water mist system is distinguished into three kinds of working pressure including low pressure (below 12 bars), medium pressure (between 12.1bars and 34.5 bars) and high pressure (over 34.5 bars)
  5. What is difference between fog and mist?
  6. Fog is a cloud that reaches ground level, even if that "ground" is a hill or mountaintop. Mist forms wherever water droplets are suspended in the air by temperature inversion, volcanic activity, or changes in humidity. Fog is denser than mist and tends to last longer.
  7. How do I test my water mist?
  8. Testing of Water Mist Fire Fighting System
    All section solenoid valves must be in closed position and water supply valve to be kept open.
    Open the pump drain valve.
    Turn the select switch to manual in pump starter panel.
    Start the pump.
    Check the pump and discharge pressure.
    Stop the pump.
  9. What is the difference between sprinkler heads and water mist nozzles / systems?
  10. Sprinkler heads are used only for sprinkler systems and water mist nozzles are used only for water mist systems. Both systems suppress or extinguish fires with water... Water mist nozzles may have single or multiple orifices
