Water Mist Standard :

FOGEX Systems are are installed in accordance To NFPA 750 standards

Definition of Water Mist System (NFPA 750):



Water mist systems have been proven effective in controlling, suppressing or extinguishing many types of fires. Potential applications include the following

  • Gas jet fire.

  • Flammable and combustible liquids.

  • Hazardous solids, including fires involving foam furnishings.

  • Protection of aircraft occupants from an external pool fire long enough to provide time to escape

  • Ordinary (Class A) combustible fires such as paper, wood, and textiles

  • Electrical hazards, such as transformers, switches, circuit breakers, and rotating equipment

  • Electronic equipment, including telecommunications equipment

How Does HP Water Mist Work?



FOGEX extinguishing mechanism: 3 Dimensionally

  • Cooling

  • Inerting – Oxygen depletion at the source of fire

  • Radiant Heat Absorbtion

  • Cooling

    when turning into vapor water absorbs more heat than any other extinguishing agent (> 2 MJ/kg)


    droplets absorb and scatter heat radiation

  • Oxygen depletion (Inerting)

    Small droplets turn to vapour faster than bigger droplets during Vaporisation process


    Water volume expands 1640 x when turning to vapour (steam) [>100°C]


    Vaporisation (steam) ‘blocks’ oxygen locally from fire source

  • Radiant Heat Blocking

    High mist density (small droplets)


    Absorbs & scatters heat radiation - prevents fire spread
