Operating Principle
The RC Water Mist Nozzle converts high-pressure water into ultra-fine droplets that suppress fire through three primary mechanisms:
- Rapid Cooling: Fine droplets absorb heat quickly, reducing the fire temperature.
- Oxygen Reduction: Water droplets evaporate into steam, locally reducing oxygen concentration around the fire.
- Radiant Heat Blocking: The mist forms a protective barrier that limits radiant heat transfer and helps prevent fire spread.
This technology provides highly effective fire suppression while using significantly less water than conventional sprinkler systems.
