Fuel Polishing & Cleaning of Diesel Generators

Fuel Polishing & Cleaning of Diesel Generators

Fuel polishing and cleaning is critical to the ability of diesel generators and/or fire pumps to operate in an emergency. It also is the key to preventing costly repairs and downtime due to issues such as fuel injection pump replacement.

What is fuel polishing & how do you maintain healthy fuel?

Fuel polishing and cleaning of diesel generators is the process of drawing the fuel from the tank through a filter system and back into the tank. During this, it constantly circulates that fuel through the filter. This captures all the water and elements that have accumulated in the diesel fuel.

The best way to maintain healthy diesel fuel, is by consistently following a proven diesel fuel and fuel tank maintenance program.
