Dirty Diesel Fuel Only Costs You Time and Money

The quality of today’s diesel fuel has not advanced it in fact has deteriorated. Today’s diesel fuel contains more asphaltene solids and water than the fuel of just a few years ago.

Asphaltenes are components of asphalt that are generally insoluble and are present to some extent in all diesel fuel. These black, tarry asphaltene are hard and brittle, and are made up of long molecules. Fuel with a high percentage of asphaltene will drastically affect the engine performance by reducing the ability of the fuel to burn completely. Asphaltenes also shorten the life of a fuel filter. 

Water is the greatest concern because it is the most common form of contaminant. Water may be introduced into the fuel supply during fueling when warm; moisture laden air condenses on the cold metal walls of fuel storage tanks or from poor housekeeping practices. The effects of water in diesel fuel can be serious. Water can cause a tip to blow off an injector, or reduce the lubricity of the fuel which can cause seizure of close tolerance assemblies such as plungers
Understand that most fuel has some amount of water in it from either condensation, the pipeline, the storage facility or the transporter.
Water displaces the diesel fuel. When the fuel is displaced wear occur because lubrication is now absent.
Water that enters the combustion chamber results in even more serious damage. When it comes in contact with the heat of the combustion chamber it immediately turns to steam and often explodes the tip of the injector. Water causes corrosion of tanks, lines, injectors, and greatly reduces combustibility.
It is estimated that eight out of every ten diesel engine failures have been directly related to poor quality and contaminated fuel. The build-up of contaminates in the fuel systems and storage tanks can quickly clog filters, thus resulting in engine shut down, fuel pump wear, and diesel engine damage.
The Dieselcraft Fluid Engineering has developed a “Fuel Purifier” that removes over 99 percent of the water and over 95% of the natural contaminates found in diesel fuel. This is all done without the use of replaceable, changeable or cleanable filter elements. There are no moving parts, except the fuel inside the purifier. There are no elements to clean and dispose of, only purging the water and particulates.
Cleaner fuel reduced downtime, extends pump and injector life, as well as adds two to three times the filter life.
Dieselcraft manufactures several models to fit any application. The smallest unit is the Model 3x8, that measures 3 inches in diameter by 8 inches long and with a flow rating of 240 GPH or engines with less than 200 HP and the largest is the Model 16x74 ( 16 inch diameter by 74 inches tall) that can handle flows to 24,000 GPH.
The Dieselcraft Purifier can be mounted on the engine, at the fuel dispensing pump, where it cleans the fuel before it goes into a vehicle or in a fuel polishing and re-circulating application.
Sold through distributors’ world wide. See the company website for nearest sales office.
