Fuel Filtration – Polishing

Diesel Polishing System and Fuel Tank Cleaning System

All fuel types begin to deteriorate by moving away from refinery properties over a period of time due to temperature, humidity and other effects. Water and sediment formation begins at the bottom of the tank due to microorganisms and particles. In addition, suspended water particles are formed in the fuel. Over a period of time, both the quality of the fuel decreases and its color deteriorates. In addition, it causes malfunctions by clogging the injectors in the system (land vehicles, aircraft, generators, burners, dynamic UPS etc.) To prevent this, fuel tanks must be maintained. As Neftgen, we provide continuous maintenance with the Diesel Polishing system, while with the Tank Cleaning System, which is our own production, we allow you to remove the sediment and water at the bottom of the tank and get rid of the water particles in the fuel.

Our Fuel Filtration Polishing products are manufactured from extremely high quality parts.

Fuel Polishing — FAQ

Common questions about fuel polishing — faq from Neftgen.

What is fuel polishing?+
Fuel polishing is the process of removing water, sludge, microbial growth and particulate from stored diesel to bring it back within specification. Neftgen fuel polishing systems filter and recirculate tank fuel so generators start on clean, dry fuel.
Why does stored diesel need polishing?+
Diesel degrades in storage. Condensation, microbial growth and settled particulate form sludge that clogs filters and can stop a generator exactly when it is needed — a critical risk for data centers, hospitals and standby power.
What contaminants are removed?+
Free and emulsified water, fine particulate, microbial contamination and sludge — restoring fuel toward recognised ISO cleanliness targets.
How often should fuel be polished?+
It depends on tank turnover, storage time and site conditions. Systems can run on a periodic schedule or continuously with automated controls that keep fuel in spec year-round.
Can polishing be built into a tank or generator system?+
Yes. Neftgen supplies fuel polishing as a standalone skid or integrated with day tanks, bulk tanks and generator fuel systems.
Is the system built to a quality standard?+
Yes — Neftgen designs and manufactures under ISO 9001, with filtration sized to the tank volume and the fuel condition.
