5 Tips to Maintain Diesel Exhaust Fluid Purity

Maintaining Diesel Exhaust Fluid (DEF) purity and concentration is vital to the efficient and long-term operation of the SCR system.

Use the 5 tips below to make sure your DEF is pure.

1. Use API certified Diesel Exhaust Fluid. Using Diesel Exhaust Fluid that meets ISO standards provides the foundation for purity throughout the distribution process.
2. Buy from a supplier that uses a Closed Loop System.
3. Dedicate nozzles, pumps, and tanks that are specifically designed for DEF. Traditional lubricant equipment is not compatible with DEF and cause damage to your SCR equipped trucks.
4. Keep DEF fluid out of direct sunlight and avoid extreme fluctuations in temperatures.
5. Training – Build awareness about the importance of purity with your team.

Following these simple steps should prolong the life of your SCR equipped trucks.

What is Diesel Exhaust Fluid?

It is a nontoxic solution of 67.5% de-mineralized water and 32.5% urea. The urea used for Diesel Exhaust Fluid is automotive-grade. When injected into hot exhaust as a fine mist and passed over a catalyst, Diesel Exhaust Fluid helps convert NOx into nitrogen gas and water vapor. Diesel Exhaust Fluid is stable, colorless and odorless, and classified as a non-hazardous material.

When will I need it?

EPA 2010 vehicles equipped with Selective Catalytic Reduction (SCR) technology will use Diesel Exhaust Fluid, also called DEF. Wide production of these vehicle will not occur until mid 2010.

How is it used?

DEF it stored and a tank much like your current diesel tank and is mixed into the downstream of your exhaust to react with heat and catalyst to bring your emission to nearly zero.

How much will I need?

A safe rough estimate is 2% of your fuel usage.

Where can I get it?

DEF will initially be supplied in smaller quantities; 1, 2.5 and 5 gallons, at most fueling locations you currently use. You will also be able to order directly from DeWitt Petroleum in varying quantities including those listed previously and up to 330 gallon or bulk.

Is DEF classified as hazardous?

No, DEF is classified as a non-hazardous material, therefore you can safely store DEF at your location to fill you tanks as needed.

What if my truck runs out while on the road?

Your driver should have ample warning to get to the nearest fueling location that has a supply of DEF with lights and buzzers prior to running out. Though should the driver run out prior to this happening the truck will still run though at a much lower performance level (45mph top speed). Should the driver attempt to stop and restart the truck the driver may find that they are unable to restart the vehicle without first filling the DEF tank.
