Njord Diesel Polishing Systems

Njord automatic Fuel Filtration Systems are recommended for use on board yachts that have 12 or 24 Volt DC or 110, 230, 400 Volt AC available. They can also be used for industrial Fuel Polishing applications inside a building

Each fuel tank is its own biosphere. Diesel fuel is naturally unstable and forms sediments over time. As water enters the tank with the consumption of fuel through the air pipe, micro-organism contamination is always a threat. The drastic reduction of sulfur and addition of bio-components to diesel fuel in recent years have further reduced shelf life and increased fuel related headaches. To make sure your engines or generators run reliably and efficiently on (bio)diesel, it is strongly recommended to install a fuel polishing system on board.

To bring and keep the fuel in spec and meet the engine manufacturers’ fuel cleanliness requirements, it is essential to keep water content below 70 ppm and reach at least an 18-16-13 ISO 4406:1999 particle size distribution. Multi-pass filtration with a water absorber and absolute filter elements with a high Beta ratio for filtration below 5 micron are required. This is realized using the Njord automatic Fuel Polishing Systems running in a parallel recirculation loop to the fuel tank. The system can then also be used to transfer clean fuel from one tank to another.
