Why Is Fuel Polishing Necessary?

Fuel polishing is a cleaning process that is necessary to remove or filter contamination from diesel oil fuels. It is particularly important when diesel has been stored in a fuel tank for a long period, because it can deteriorate and negatively affect the whole system. In the worst-case scenario, contaminated fuel could even cause a system failure.

What exactly is fuel polishing?a

Polishing of fuel refers to an advanced mechanical cleaning process which removes build ups of sludge, sediments, and water caused by microbial contamination. The fuel is extracted from the tank during the polishing process, and then any solids and contaminants are removed. The clean fuel is tested and then filtered back into the tank.

What are the benefits of fuel polishing?

Contaminated fuel causes heating systems to run inefficiently, meaning that bills will be higher. The system may even be liable to developing faults and cease to operate altogether. If the fuel is left too long without polishing, it may deteriorate to the point where it becomes unusable, and the whole batch will need replacing.

Carrying out a fuel polish is less expensive than paying to replace and dispose of the contaminated fuel. It will also prevent the build-up of water and sludge in your tank, thus prolonging its lifespan and safe operation. Avoiding the need to dispose of unclean fuel is also an environmentally responsible approach.

How often should fuel be polished?

This depends on what the fuel is used for, but generally once a year is recommended. This is especially relevant to fuel stored in generator tanks which is intended for back-up power supply purposes.

How long does fuel polishing take?

This depends on the tank size, the current condition of the fuel, and the amount of fuel that needs polishing. However, the whole process can be carried out with no disruption to the running of machinery and equipment.
