Bad fuel, dead batteries and coolant problems are the leading causes of generator failure to start when needed. A mandate from the EPA in June 2006 to lower the sulfur content of diesel fuel to no more than 15 parts per million has created an environment where contaminants proliferate. Algae, sediment and especially water need to be removed from your fuel to insure proper performance of your diesel engine. Damage to injectors and other mechanical components are much more likely to occur if these contaminants aren’t routinely removed from your fuel supply.
It is possible to get water in the fuel tank as part of the delivered fuel, leaks in the tank, gauges, caps or seals, as well as by condensation through fuel vent lines. Condensation is an especially serious problem where the relative humidity tends to be high and ambient temperature changes are frequent. The longer fuel is stored before being consumed, the more susceptible it is to contamination. Back-up generators are by the nature of their role extremely vulnerable. Most of these units run just a few minutes weekly and thus the fuel can be stored for years before being consumed. The higher the content of suspended water molecules, the more likely the presence of microbial growth (algae). Sediment can be introduced through rust (accelerated by the presence of water) and other atmospheric conditions.
Ship Supply’s certified technicians use state of the art equipment to filter out these contaminants without affecting the generators’ ability to provide power during the service. Our process utilizes an aviation grade water coalescer and filtration that removes particles as small as 1 micron. After removal of the water, sediment and algae, Ship Supply puts additives in the fuel that stabilize the fuel and enhances its performance.
A micron is a metric measure equal to one millionth of a meter, or 1/25,000th of an inch. The smallest particle visible to the naked eye is 40 microns across. A human hair is 80 microns in diameter, and a single grain of talcum powder is 15 microns.
Because of the wide range of site specific conditions, fuel supply and other factors that contribute to the reliability of your fuel stores, our recommendation is to allow us to obtain samples of your fuel from the units themselves. We can perform a combination of visual and laboratory tests to ascertain what level of service may be required in each case.
Most storage tanks contain on or off road diesel. Typically, we can perform our service and restore the current fuel to a fully functional state. In rare cases the fuel has deteriorated to a level that won’t allow us to provide you with a quality product. In these scenarios we recommend replacing the fuel.
