Foam Chambers

Foam Chamber is designed to discharge expanded foam directly onto the surface of a flammable or combustible liquid for fire extinguishment.

Classified as a Type II discharge device in accordance with NFPA Standard 11, foam chamber delivers low expansion foam directly onto the fuel surface. Minimizing submergence and agitation increases the effectiveness of the foam blanket, resulting in more efficient operation, and superior extinguishing capabilities. HD foam chamber is UL Listed and FM approved. Foam chamber is available in four sizes and comes along with foam deflector.

Foam Chamber is used in one of the most common applications to protect vertical fixed roof (cone) liquid storage tanks, with or without internal floating roof with the low expansion foam system. HD Foam Chambers are UL Listed and FM approved. Foam Chamber Glass Vapour Seal is field replaceable. Please contact our sales for further details on approvals and certifications.

Vapor Seal

Predictable rupture assemblies

Precision-scored glass vapor seals prevent hazardous tank vapors from escaping into the piping. Designed for reliable, clean rupture under low system activation pressure.

Shell Construction

Corrosion-resistant steel

Heavy-wall carbon steel bodies feature durable internal coatings to withstand harsh petrochemical environments and marine exposures. Built for decades of standby readiness.
