Diesel Fuel Filtration Specialists

​Diesel ​Fuel Supply & Filtering

to allow the diesel fuel to circulate to achieve meaningful filtration. The diesel fuel is, however, subjected to injector pump pressure and extreme heat that warms the fuel returning to the storage tank and encourages condensation to form in the tank bottom providing an attractive environment for microbial contamination to thrive. Fuel filters are changed during normal oil changes, typically twice per year. The amount of run time for the fuel is not enough to allow contaminant build-up on the filter to reveal to the maintenance personnel that there is a diesel fuel contamination problem. Biocide additives are repeatedly added to the same fuel to deal with microbial activity, but this process accelerates fuel deterioration causing solids and debris to settle in the tank. Fuel samples are tested for microbial and fungi activity, but results are negative. Fuel quality, it is assumed is being maintained.

As engines are tested, the diesel fuel is continuously re-circulated and exposed to extreme pressure and heat, which results in the agglomeration of asphaltines, the high carbon content, heavy end fuel molecules. This process leads to the formation of larger and larger clusters and solids, which are very difficult to completely combust. These solids may grow so large that they create larger fuel droplets, too large for efficient combustion to occur.

More than 90% of the debris and the sludge in your tanks is organic material, fuel and oil breakdown residue. In most cases, this debris is acidic and not good for your engine. It causes corrosion in injectors, pumps and storage tanks. Even though microbes may cause and accelerate the process of fuel degradation, it should be clear that the waste products causing the problem are not the microbes but fuel components which have formed solids.

It is not until the power goes out, and the fuel circulates for possibly less than one hour that the extent of the problem is evident, revealing itself in the form of a generator shut-down from lack of diesel fuel, the result of a clogged diesel fuel filter. Repeated filter changes treat the symptom, but then adding fuel stirs up debris in the tank and problem continues.

Maintenance personnel without knowledge of what is really going on add filters and pour in more biocides. Other systems available on the market claim to polish the fuel, but just filtering does not address the fuel deterioration problem.

Give a diesel engine clean fuel and it will run forever. Repair statistics show that 90% of diesel engine problems stem from contaminated fuel. The promise of eliminating 9 our of 10 potential failures should put fuel-system maintenance at the top of your list.

Diesel Fuel Filtration Specialists is a fuel purification company delivering diesel fuel and specializing in fuel polishing and the removal of algae, fungus, bacteria and water from diesel fuel. Our PREVENTIVE FUEL POLISHING MAINTENANCE PROGRAM eliminates power failures caused by contaminated, aging and idle tanks.


Diesel Fuel Management is an Important Part of Generator Service!

The need for reliable backup electric power is too important to leave to chance. Emergency power generators that rely on diesel fuel are at constant risk of unexpected failure due to clogged fuel filters when the diesel fuel is allowed to degrade and contamination occurs. Steps need to be taken to assure a reliable, long term source of quality diesel fuel for emergency generator systems. The standard in the power generator industry is to simply run the backup generator system periodically, maybe once each month for 30 minutes or until it reaches operating temperature. This is not enough time
