Foam Chamber

SOLBERG Foam Chambers are NFPA-11 Type II air aspirating foam discharge devices that provide protection for open top floating and cone roof flammable liquid storage tanks. Foam chambers are a combination of a foam mixing chamber and a foam maker with an air inlet. A removable orifice plate is located between the flange inlet and solution pipe flange and is sized to deliver the required foam solution at a specified pressure. A frangible glass vapor seal located in the foam chamber body prevents product vapours from entering the foam chamber body. The vapor seal will break once the foam solution enters, filling the foam chamber body with expanded foam. The foam flows to a deflector plate, which directs the foam to the inside of the storage tank wall and fuel surface, only allowing minimum foam submergence and fuel agitation.
