Foam generator OFGR

Over-the-Top Foam Generators are air aspirated discharge devices that are installed on the outside wall of liquid storage tanks above the level of the stored product. They produce and inject foam onto the liquid surface. SKUM manufactures two types of Over-the-Top Foam Generators, depending on the storage tank construction type. SKUM can supply the OFG and OFGR models to a range of performance specifications and multiple build options. OFG and OFGR foam generators produce foam with expansion ratios of up to 4:1, depending on the foam concentrate type and capacity requirements. The OFG standard models consist of a stainless steel body with a removable back cover, brass nozzle, gas stop, and hot dipped galvanized slip-on inlet and outlet flanges. A stainless steel FIH (foam inlet head) foam pourer with a carbon steel weld-on flange is designed for use with the OFG and is avail able as part of a package or sold separately. The FIH directs the foam from the OFG foam generator down the side of the tank to reduce the submergence of the foam and agitation of the fuel surface. The OFGR standard models consist of a stainless steel body with a weld-on back cover, brass nozzle, and hot-dipped galvanized slip-on inlet flange. The body of the OFGR includes the foam pourer that can be mounted to the top flange of the fuel storage tank. The OFGR T models have a removable back cover for access during testing. A separate test plug is available for use with the OFG and OFGR T models. This plug enables testing without discharging foam into the storage tank.
