Our Foam Fire Extinguishing System is effective in extinguishing large areas of liquid fire especially fires in oil fields, petrochemical works, oil depots, etc. They are available in low, medium & high foam expansion categories based on the expansion of the foam, which ranges from 0.5 to 18m3.

Foam systems produce an aggregate of air filled bubbles from a concentrated aqueous solution of foam. Foam systems work on the principle that they produce a blanket over or around the fire resulting in exclusions of oxygen and thus extinguishment. They are classified by their expansion ratio.

Low expansion foam – with expansion ratio between 1 and 20, it is used primarily for application to the surface of flammable liquid fires.

Medium expansion foam – with expansion ratios between 21 and 200, it used for surface application or for fires which requires coverage of up to 4m depth of foam.

High expansion foam – with expansion ratios between 201 and 1000, it is intended for filling enclosures at different levels and is used most efficiently in indoor spaces.
