High-Performance Fuel Polishing Systems

Your Emergency Fuel System Depends on Clean Fuel

When business continuity depends on the reliable performance of your fuel transfer system (FTS) to power your emergency generators, the fuel in your FTS must be of optimal quality. Fuel can become contaminated with dirt, rust, and other types of sediment that clogs the filtration system and wears down the mechanical components of your FTS.

Proper fuel maintenance will help keep your fuel supply system operating at peak performance and reduce your equipment repair and replacement costs by extending the life of your fuel transfer system. Since 1996, ISP has been completed hundreds of mobile fuel polishings for hospitals, financial institutions, schools, sports arenas, data centers, and other mission-critical facilities.

Fuel Polishing – Before & After

What Is Fuel Polishing?

Fuel polishing is a technical cleaning process that uses filters, and coalescers to remove contaminants like water, dirt, sediment, and microbes from diesel and other fuels. Fuel polishing systems maintain fuel at optimal quality to protect your fuel transfer system and emergency generators from becoming damaged and inoperable. During the fuel polishing process, fuel is continually circulated from the tank through a mobile filtration system that can fit through most standard doorways and elevators.

The mobile filtration system is designed to remove water, sludge and sediment before returning the fuel back into the tank. One of the benefits of using a mobile system is the ability to target certain sections of the tank where water, sludge and sediment are found. It is recommended to run the total amount of fuel through the system 2-3 times over for best results.
