Datasheet 1009/20 > Page 1 of 2 (replaces datasheets 1009 / 6; 7; 9) General description Over the top foam generators are installed to theoutside wall of liquid storage tanks above the level of stored product, producing and injecting foam onto the liquid surface. Two types of OFG are available, the OFG and OFGR,used for different types of tank construction, with a range of product performance and build options as described below Application description The OFG is connected to a foam concentrate supplyto deliver foam onto the liquid surface within the tank. OFG units are suited to both fixed and floating roof storage tanks and are fitted with an in-situ test feature, accessed via an external test cover, enabling OFG test without discharging foam into the storage tank.To select appropriate performance characteristics,refer to NFPA: National Fire Codes NFPA 11 and/or local regulations.
