By dispensing powder through a fixed piping system and special nozzles, the pressurized powder system empties its extinguishing agent onto the flame, suppressing and extinguishing the fire.
Depending on the combustible to protect, the appropriate class of powder must be chosen. Although it may cause more collateral damage than gas or water mist systems, it certainly represents the most versatile extinguisher, as it can be used on solids, flammable liquids and electrical equipment alike.
Through a propellant gas, the powder is discharged onto the zone of interest and through its heat-absorbing, smothering and cooling action, it guarantees the fire is extinguished.
