Foam Chambers and Foam Makers are air-aspirating foam discharge devices designed to protect flammable liquid storage tanks by applying foam down the inside wall of the tank.
Foam Chambers are designed to generate foam and apply the expanded foam to the fuel surface in a manner that lessens submergence and agitation as the foam contacts the fuel.
Foam Makers include High Back-Pressure, Floating Roof Foam Makers, and Rim Seal Foam Pourers. High Back-Pressure Foam Makers are designed to generate expanded foam for the purpose of subsurface injection into a cone-roof liquid hydrocarbon storage tank. Floating Roof Foam Makers (FLR) and Foam Pourers are air-aspirating foam discharge devices that are designed to protect floating roof, flammable liquid storage tanks.
