Biocide Treatments

When microbial contamination has infiltrated your fuel supply, the judicious use of biocide is recommended. Clean Fuels National is a proud distributor of Grotamar 71.
Grotamar® 71 from Schülke is a liquid biocide preservative for diesel fuels that rapidly kills and controls microbial contamination. Grotamar® 71 has a broad, balanced spectrum of effect (including sulfate-reducing bacteria), as well as outstanding anti-corrosive properties. Grotamar® 71 has good solubility in both diesel fuel and in water. Grotamar® 71 contains no nitrate, nitrosing agents or organically bound chlorine – therefore it has no effect on the AOX value. Grotamar® 71 is a safe, long-lasting preservative with a proven history of effective use for over 50 years.

This product is exceptional at eliminating biological contamination in diesel tanks, but killing the microorganism is only part of the solution. When these organisms die off, they create catastrophic particulate problems within the tank, thus; treatment with biocide must be followed with a thorough tank cleaning and fuel filtration.
