Product Description

Grotamar 82® 

The first biocide with a new protective formula for modern diesel fuels

Modern low sulphur marine diesel fuels may contain biodiesel

Biodiesel

  • encourages microbial growth or “diesel bug”
  • can degrade in storage within a few months leaving deposits in the fuel system

Low sulphur

  • can cause increased leaching of copper and other metals into fuels making them unstable

 

Grotamar®82 improves on and replaces grotamar®71

  • based on the same highly effective active ingredient:
    • recommended in trials by Motor Boat Monthly and Practical Boat Owner magazines
    • used by NATO and the Royal Navy
    • approved by engine manufacturers including MAN, MTU, DAF, Mercedes-Benz AG

 

Grotamar®82 – what’s different and better

  • specifically developed for modern diesel fuels, including biodiesel and low sulphur fuels
  • new protective formula to prevent premature fuel degradation caused by ageing
  • fast and highly effective against bacteria, yeasts and moulds
  • excellent long-term protection for fuel tanks, pipes and engines
  • rapid and complete dispersion in all fuels – no mixing required
  • no corrosive combustion products
  • corrosion protection for steel, aluminium, copper and other non-ferrous metals
  • easier dosing
    • preventative dose: 200ml per 800ltrs of fuel; 1Ltr per 4000 ltrs of fuel
    • shock dose: 200ml per  200 litres of fuel; 1ltr per 1000ltrs of fuel

Can I use Grammar 82 in conjunction with other fuel additives?

Whilst Grotamar® 82 is generally suitable for use in a wide range of fuel applications, the manufacturers can not 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.
