Overview

High Expansion Foam Systems are generally used to protect indoor or compartmented hazardous areas involving flammable liquid fires where it is necessary to use the minimum amount of water.

These systems use a water powered generator fan. When the foam water solution is discharged through the unit, the powerful air stream created by the generator fan immediately expands the foam, which rapidly engulfs the protected area.  The expanded foam quickly creates a blanket across the burning fuel depriving the fire of oxygen that in turn extinguishes the fire.
