    Fuel Polishing

    Fuel quality is crucial for fleets, trucks, and heavy equipment. From damaged engines to increased sulfur emissions, dirty fuel can affect business operations in numerous negative ways. To prevent these expensive problems, it’s important to maintain fuel quality with diesel fuel polishing.

    The Fuel Polishing Process

    • A return/intake hose is inserted into the tank down to the bottom where most contaminants like water and bacteria accumulate.
    • The intake hose then draws in the contaminated fuel – water and bacteria included.
    • The contaminated fuel passes through separate filters, depending on the type of contaminants.
    • Contaminants can be monitored through a clear section of the intake hose.
    • The intake hose is re-positioned in the tank to make sure all areas are clean.
    • At high velocity, the clean fuel is then returned to the tank through a return hose. This also flushes any leftover contaminants into the intake hose to continue the process.

    Real Proven Results

    NFPA 110 “Standard for Emergency and Standby Power Systems” is the standard for people who own and operate buildings with emergency generators. It’s the starting point of what a building owner should consider as good practice and may go further toward a legal requirement since it is referenced in building codes. ASTM gets drawn into this through NFPA 110 Part 8.3.7: A fuel quality test shall be performed at least annually using appropriate ASTM standards.

     Five Reason to Clean Diesel Fuel Tanks. Eliminate downtime: damage to fuel injection systems are costly in time and dollars. Stop emergency service calls: clogged filters and water in fuel will ground your fleet until help arrives. Prevent emergency generator shutdown: Gen-Sets sit idle for most of their life, water will accumulate and microbe contamination will grow at the tank bottom. Reduce fuel tank corrosion: acidic sludge accumulates in fuel tank bottoms from microbe clusters. Increase engine performance: clean, dry fuel helps your engine run smoothly.

    Contaminated Diesel Fuel Symptoms

    Knowing if you have dirty diesel is simple. You will notice:

    • Dark and hazy coloring
    • Filters are clogged and slimy
    • Tanks have floating debris and sludge
    • Corroded fuel injectors
    • Bad smell from the fuel tank
    • Loss of RPM and power
    • Increased exhaust smoke
