Water sprinklers don鈥檛 starve flames of oxygen鈥攕o Cologne-based Fogtec
has developed an extinguisher that makes a water mist do the job. The firm鈥檚
High Pressure Water Mist is produced by pressurising water to 100 atmospheres
before passing it through a nozzle, causing abrupt vaporisation. The high
density of tiny droplets in the fire region provides a much larger water surface
area than a sprinkler. The mist has the additional benefit of not waterlogging
expensive electrical equipment.
