  • How much Grotamar®82 do I need?

    Preventative Dose Rate:

    • 200 ml of Grotamar® 82 to 800 litres of fuel
    • 1000 ml of Grotamar® 82 to 4000 litres of fuel

    Shock / Decontamination Dose Rate

    • 200 ml of Grotamar® 82 to 200 litres of fuel
    • 1000 ml of Grotamar® 82 to 1000 litres of fuel
  • Can I use Grotamar®82 in conjunction with other fuel additives?

    Whilst grotamar® 82 is generally suitable for use in a wide range of fuel applications, the manufacturers cannot possibly investigate its compatibility with all additives on the market, therefore their advice is to use caution and try to avoid use with other products.

    If you wish to test compatibility remove fuel from your system containing the other additives in question into a small fuel compatible container.  Add grotamar®82 to the isolated fuel sample and observe the fuel for any over a suitable time scale before adding to the fuel in the system.

  • Are there any problems I might encounter when using a biocide?

    After a contaminated fuel system has been treated with an effective biocide, the microbes present will die.  The microbes dead bodies will persist in the fuel system and fall off any surfaces where they have been growing into free suspension in the fuel. Therefore it is important that post biocide treatment, settling sludge should be removed from the system.  For ships it is therefore very important to carry sufficient filters to enable filter changes should it be necessary until all the sludge is removed from the system.

    Where a large amount of sludge is known to be present in systems, it is advisable to remove this before treatment as biocides are unlikely to penetrate sludge layers.

  • Are grotamar® products compliant with any regulations?

    Yes, grotamar® products comply with the Biocidal Products Regulations (BPR Regulation (EU) 528/2012) and the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).

  • How do grotamar®71 and grotamar®82 differ in their application?

    grotamar®71 is a concentrated form of the active ingredient, ideal for blending and use at refineries and in the fuel supply chain. grotamar®82, on the other hand, is designed for easy dispersion without mixing and is formulated with anti-oxidative and anti-corrosive properties, making it suitable for end-users and fuel containing biodiesel content up to 20%.

  • Can grotamar®71 and grotamar®82 be used in all types of fuels?

    Both grotamar®71 and grotamar®82 can be used in a wide range of middle distillate fuels, including modern diesel, marine fuels, and heating oils. However, they are not approved for use in aviation fuels.

  • Are there any special handling requirements for these biocides?

    grotamar® products should only be used by professional users and commercial operators. Appropriate safety measures and guidelines should be followed when handling these biocides.

  • What approvals do grotamar® biocides have?

    grotamar® biocides have approvals from leading engine manufacturers such as MAN, DAF, MTU, and Mercedes-Benz AG. They are also NATO-codified and trusted by defence services worldwide.
