Biocide used to inhibit fungal growth in fuels. Kills the bacteria that clogs filters, plugs fuel lines & produces injector nozzle deposits which cause engine failures. Sterilizes fuel systems by destroying sludge & slime. Used by missile and space contractors who can not tolerate malfunctions due to contaminated fuel systems. Also used in marine diesels, gas turbines & jet engines of major airlines. Cuts maintenance costs by keeping tanks clean and lines clear - reduces filter and injector cleaning and replacement. Used at 270 ppm to effect sterilization and 135ppm to maintain fungus-free fuel.
