Foam Chamber

The Chemguard Foam Chamber consists of a foam expansion chamber and an integral foam maker.The foam chamber is installed on a flammable liquid storage tank just below the roof joint. The foamsolution is piped to the chamber from outside the hazard area. Upon entering the chamber, the foamsolution is expanded and then discharged against a deflector inside the storage tank. The deflectordirects the foam against the inside wall of the storage tank. This reduces the submergence of the foamand agitation of the fuel surface. (NFPA Type II Application)
