Foam Chambers

Low Expansion Synthetic Fluorine Free Foam (SFFF) systems are comprised of various FM Approved and/or UL Listed components to establish a complete package for flammable liquid protection. Included in the package are foam chambers, which are suitable for the protection of fixed roof-mounted tanks and are to be used as low expansion Type II discharge devices (as defined by NFPA 11), with approved and/or listed foam concentrates and proportioning devices.

Foam chambers are designed to apply an expanded foam blanket over the surface of an ignitable liquid fire as gently as possible to achieve extinguishment and/or vapor suppression. Typical applications include manufacturing plants, large tank farms, oil refineries and chemical plants. Foam chambers are UL Listed with the Viking USP (Hydrocarbons only) concentrate at an application rate of .1 gpm/sq ft.
