    • ValvTect Bioguard ULS Fuel Biocide is effective in gasoline, diesel, biodiesel blends and heating oil
    • Kills bacteria ("bugs"), yeast, mold, and other microorganisms
      • Kills bacteria in the fuel and water phase
      • Prevents bio-contamination of fuel system
      • Prevents bacteria caused filter plugging
      • Prevents bacteria caused fuel line plugging
      • Prevents and breaks up bacteria caused sludge and slime
      • Prevents bacteria caused corrosion
    • Microorganisms, like bacteria, yeast and mold are known as "bugs"
    • "Bugs" live in virtually all diesel fuel systems
      • Wherever there is moisture and fuel together there is a good environment for biological growth
      • The most common places for contamination include the fuel/water interface near tank bottoms, on storage tank walls, and in tank bottom sediment
      • Microorganisms live in the water found in all fuel systems and eat the fuel as a nutrient source
      • Sulfur provides some natural protection against bacteria growth
      • However, with the introduction of ULSD fuels, there is minimal natural protection to prevent biological growth in fuel systems
      • Left unchecked, "bugs" will corrode fuel systems and create slime & sludge that plug fuel filters and fuel lines
      • The result is increased maintenance costs and expensive down time. BioGuard™ ULS is an EPA registered, fuel & water soluble, dual phase microbiocide that effectively kills bacteria, fungi & other microorganisms that grow in gasoline, diesel fuel, biodiesel blends and heating oil storage tanks
      • It also helps prevent fuel system contamination from new infections. BioGuard™ ULS can be used in association with ValvTect's Tank Maintenance Program as a proactive way to check your fuel system for bacteria contamination and address excess water & biological contamination before it causes maintenance issues
    • Works faster & more effectively (as little as 2-3 hours)
    • Prevents equipment down time
    • Safe for use in on-road and off-road fuels
    • Initial Treat Rate 1:2500

    *Maintenance Treat Rate 1:7400

    • 16 oz bottle treats 460 gallons at initial treat rate and up to 920 gallons for maintenance dosage
    • 32 oz bottle treats 920 gallons at initial treat rate and up to 1840 gallons for maintenance dosage.
