Fuel polishing is a critical process for diesel generators. It involves removing diesel from the tank, filtering it, and returning it to the tank. This process removes impurities, such as water, sediment, and microbial contamination, that can cause engine failure and costly repairs. Fuel polishing is especially important for generators that are infrequently used and have fuel stored for long periods, as diesel fuel can start to degrade within 3-6 months. By regularly polishing diesel fuel, generators can avoid breakdowns and ensure reliable performance when needed. The process can be done through automatic polishing units or by hiring a professional technician, both of which are more cost-effective than dealing with generator issues due to contaminated fuel.

Fuel polishing prevents the build-up of sludge, water, and microbes in your generator
Fuel polishing is a critical aspect of generator maintenance, particularly for diesel generators. It involves a three-stage process of fine filtration that effectively removes impurities, including water, sludge, sediment, and microbial contamination. By drawing fuel from the generator tank through a filter system and returning it to the opposite side of the tank, fuel polishing prevents the build-up of contaminants and ensures the fuel remains clean and dry.
Over time, diesel fuel can degrade, leading to the formation of sludge, sediment, and microbial growth. This is especially prevalent in emergency generator tanks, where fuel may be stored for extended periods, sometimes up to 10 years. As diesel ages, particulates fall out of solution, resulting in a gritty texture and dirty appearance. This dirt accumulates at the bottom of the tank and can cause significant issues if left unchecked.
The presence of microbes in diesel fuel further exacerbates the problem. These microorganisms feed on the diesel, producing additional sludge and particles that float throughout the fuel. Regular fuel polishing is essential to capture and remove these impurities, preventing them from clogging filters and damaging injectors, fuel pumps, and other engine components. Without fuel polishing, the build-up of contaminants can lead to engine failure and costly repairs.
To maintain optimal fuel quality and generator performance, fuel polishing should be included in the regular maintenance schedule. This can be achieved through the installation of an automatic polishing unit or by engaging a third-party vendor with specialized equipment and certified technicians. By investing in fuel polishing, you can prolong the life of your fuel and generator, ensuring reliable performance when you need it most.
Additionally, fuel testing is recommended to identify any issues early on. The ASTM D975 Standard specifies 13 different tests to evaluate diesel fuel quality. Annual fuel testing, followed by fuel polishing if necessary, can help prevent unexpected generator failures and ensure compliance with local safety codes and regulations. By prioritizing fuel polishing and testing, you can maintain the reliability and longevity of your generator while avoiding the costly consequences of neglected maintenance.

It removes impurities, dirt, and water through a fine filtration process
Diesel fuel doesn't last forever and will start to degrade 3-6 months after refining. It is an organic compound that is liable to deteriorate over time. This is particularly true for emergency generator fuel, which may be stored for long periods, even up to 10 years, before it is consumed.
Fuel polishing is a very fine filtration of diesel fuel that removes impurities, dirt, and water. This is achieved by pumping diesel fuel from a tank, through a series of filters, and back into the tank. This circulation ideally happens by drawing fuel from one end of a tank and returning it to the opposite side to avoid unfiltered fuel.
There are three main types of contaminants that can plague diesel fuel: solid particles, water, and microbial growth. Water and bacteria build up over time due to natural processes, contaminating the fuel and rendering it unfit for use. Dirt is drawn into the engine fuel supply as it operates, and excessive dirt will clog filters prematurely and cause engines to fail. Fine dirt particles passing through the fuel filter will cause excessive wear on engine components.
Fuel polishing removes these contaminants and helps to prevent the build-up of sludge in your generator and at the bottom of the tank. It also prevents clogged fuel filters and pistons and removes all traces of contamination present in the fuel, re-optimising it for your gas tank. This process can be done by a third-party vendor with specialised equipment or by installing an automatic polishing unit on the tank itself.
Overall, fuel polishing is an important process to maintain the quality of diesel fuel and prevent damage to generators.
