Avoid contaminated diesel fuel which may cause emergency generator failure

Diesel Fuel Polishing

Most emergency power system (EPS) failures are caused by contaminated or deteriorated fuel. Fuel goes through a natural process of degradation when stored, which is why the National Fire Protection Agency (NFPA) recommends that steps be taken to maintain its integrity (NFPA Standard 110).  Maintaining a fresh supply of fuel for an EPS is not as difficult as it once was.  It is now possible to filter fuel and clean the tank simultaneously rather than emptying the tank completely and disposing of contaminated fuel.  Fuel additives may also be introduced to help stabilize the fuel.

Our Goal: To meet all Florida and federal requirements for Emergency Power Systems and to create a successful fuel management program by providing preventative maintenance.

Did you know diesel fuel is considered a middle distilate and has a shelf-life of approximately 1.5-2 years? Diesel fuel is an organic compound affected by the presence of air, water and microbiological growth.

Whether you are backingup life support equipment, telecommunications, computers, fire pumps, sewer stations or any other diesel generated electricity, a preventative maintenance and monitoring program will allow for the perpetual storage of fuel when emergencies arise.
