Applications:
Fire nozzle is to use the Water Mist for Fire Suppression. Water Mist is recently developed new technology 
for fire suppression / protection. Spray nozzles is one of the key perform components in these systems.
  
Working Principle:
Cooling: small dorplets, very good evaparative cooling ability
Radiant heat blocking: vapor from the evaporation of micro-drops make a good coverage of the fire sources, flame and smoke, blocking the expansion of fire
Local oxygen inerting: the volume of the micro-drop expand up to 1500 times after evaporation, dispeling the oxygen around the fire spot.
Traditional sprinkler systems uses very large amounts of water. High pressure water mist system uses 
water much more efficiently: it uses up to 90% less water than traditional sprinkler systems for the same 
application with equivalent or better performance.
 
Adavantage: 
Highly efficient: efficient on both A- and B-class fires in laboratory tests and actual fires
Non-hazardous: water mist is completely harmless to people and the environment.
Clean: water mist uses only small amounts of plain, fresh water. It causes virtually no damage and 
requires very little clean-up.
