Foam Chambers and Foam Makers

Foam chambers and foam makers are air-aspirating devices designed to protect flammable liquid storage tanks. Foam chambers apply expanded foam gently down the inside of the tank wall onto the liquid surface. High back-pressure foam makers inject expanded foam through the tank wall near the bottom of the tank allowing foam to gently rise to the surface. Other types of foam makers are installed in the foam distribution piping where expanded foam is directed to specific hazards such as dike areas or floating-roof tank seal areas.
