Diesel Defence DD10 Fuel Polishing System

Diesel Defence on-tank fuel polishing systems offer a simple and reliable solution for maintaining diesel to EN590 standards. Through a process of recirculation fuel is continually passed through a series of filters, removing the harmful contaminants and maintaining an optimum EN590 level of cleanliness.

With a flow rate of 10 litres per minute, the DD10 is recommended for tanks holding up to 7,500 litres of fuel (dependent upon tank and fuel condition).

Key advantages of the Diesel Defence DD10 fuel polisher

  • Removes water – Advanced water coalescing filters remove virtually all free and emulsified water which can damage engine injectors.
  • Removes bacteria and solid particulates – Single and multi-stage filtration removes solid and microbial contamination to 2 microns or less.
  • Reliable fuel quality – Fuel is maintained to surpass ISO 4406’s 18/16/13 standard of cleanliness and EN590’s 200ppm level of water content.
