High-pressure water mist
extinguishing systems –
detraction of energy from the fire
and displacement of oxygen

The high-pressure water mist extinguishing system generates an extremely fine water mist by means of special nozzles and a pressure of about 120bar. As the reaction surface of the droplets in relation to the quantity of water is immense, large quantities of energy are quickly detracted from the fire and thus the temperature level is reduced rapidly. Surrounding objects will be protected efficiently from heat radiation. Through the abrupt evaporation of the droplets, additional large quantities of energy of the fire are absorbed.

At the same time, the water volume is increased 1640 times by evaporation and the oxygen contents at the source of the fire are reduced. For each individual area of application, the required type of nozzles and, therefore, the distribution of the droplets, the flow and the type of activation, will be determined individually. This guaranties an optimal protection.

The fine water mist binds a large quantity of rising soot particles. Large amounts of the water-soluble gases are washed out and the strong cooling effect provides for supportable temperatures. This renders the water mist extinguishing system especially suitable for the application in locations frequented by people.

Suitable areas for the application of
G&S high-pressure water mist extinguishing systems:

• production plants
  
• individual objects
  
• industrial- and kitchen deep fat fryers
  
• turbines
  
• dust free and sterile rooms
  
• TV studios
  
• inflammable liquids
• store rooms up to a height of 5 m
  
• archives
  
• museums
  
• hotels, offices
  
• restaurants
  

Advantages of high-pressure water-mist
extinguishing system:

• environment friendly
  
• very good human-tolerance
  
• immediate function possible
  
• reduced water requirement
  
• limited water storage is required
  
• because of the small diameter required for the
  pipes installation, the system is very suitable for
  the fitting in existing structure
