The foam chamber is designed to discharge expanded foam directly onto the surface of a flammable or combustible liquid to extinguish a fire. Classified as a Type II discharge device according to NFPA 11, the foam chamber delivers low-expansion foam directly onto the fuel surface. Minimizing immersion and agitation increases the effectiveness of the foam blanket, resulting in more efficient performance and superior extinguishing capability. The HD foam housing is UL listed and FM approved. The foam chamber is available in four sizes and comes with a foam holder.
Foam enclosure is used in one of the most common applications to protect fixed roof (cone) liquid storage tanks with or without an internal floating roof with a low expansion foam system.
