Diesel fuel stored on-site for your emergency diesel generators and fire pumps can degrade and become contaminated to the point where it will clog injectors and your diesel engines won’t fire. The turn-over rate for most diesel fuel supplies is very low as the engines are usually only tested for 1 or 2 hours each month. Emergency diesel supplies should be monitored on a semi-annual basis to ensure the fuel is of a quality to meet your emergency needs.
If excess water accumulates on the bottom of the storage tank, algae and bacteria will grow at the water/fuel interface. Dead algae will break away from the bio-mass and can become suspended in the fuel. This bio-mass can clog injectors. If the fuel has been stored for a long time, gum can form in the fuel and also clog injectors.
Our Diesel Fuel Analysis package consists of corrosion and contaminant metals, Viscosity, Flash Point, Copper Strip Corrosion, Karl Fischer Water Titration, Specific and API Gravities, Sediment by Filtration, and a microscopic visual check for algae and gum. If the sample results show a higher than 1A Copper Strip Corrosion, we conduct a Sulfur analysis to ensure the fuel meets low sulfur requirements.
