Your Diesel Exhaust Fluid Supplier

Many large diesel fleets have made changes to the technologies and materials they use for day-to-day operations. One such development is the implementation of diesel exhaust fluid (DEF).

Why is Diesel Exhaust Fluid (DEF) Important?

In 2010, the Environmental Protection Agency (EPA) mandated catalytic reduction for diesel vehicles. This regulation for nitrogen oxides (NOx) and particulate matter (PM) emissions has drastically changed the way manufacturers design engines and emission control systems.

It has become almost universal now for manufacturers to use selective catalytic reduction (SCR) technology, a post-combustion emission reduction technology that relies on a product called Diesel Exhaust Fluid. DEF is a non-toxic, colorless liquid that acts as a reducing agent in the SCR system to prevent carbon emissions from diesel engines.

Does My Fleet Really Need Diesel Exhaust Fluid?

Yes, you legally need DEF if you have a diesel vehicle. Without it, your vehicle will not only release harmful emissions, but you will also get a dashboard light telling you to reload your DEF. If you ignore the warning, your vehicle will stop running until it’s refilled.

 

SC Fuels has you covered if you are looking for reliable, competitively priced, and high-quality diesel exhaust fluid for your diesel fleet. We offer this essential product in a range of sizes and delivery methods to meet your business needs.

What is Diesel Exhaust Fluid (DEF)?

DEF is a high purity solution of urea in water. It is used in Selective Catalytic Reduction (SCR) equipped diesel vehicles to reduce NOx emissions chemically. DEF is contained in a separate tank and sprayed into the exhaust gases.

DEF is non-toxic, non-hazardous, and inflammable. Its main purpose is to reduce harmful emissions caused by diesel engines.

How Can I Order DEF?

We offer DEF in:

  • 1-gallon cases.
  • 2.5-gallon cases.
  • Drums.
  • Totes.

DEF is available at our many Cardlock locations, and we can deliver it on-site and in bulk.

How Much Diesel Exhaust Fluid (DEF) Will I Need?

For medium and heavy-duty vehicles, DEF consumption will be approximately 3% of your diesel fuel consumption. So, for every 200 gallons of diesel consumed, you would need 1 gallon of DEF.

What is Selective Catalytic Reduction (SCR)?

Selective catalytic reduction (SCR) is one of the most cost-effective and fuel-efficient vehicle emissions control technologies available to reduce diesel engine emissions. For passenger cars and light-duty trucks, the ability to meet strict emissions and fuel efficiency guidelines affordably without compromising driving power and performance is attractive. However, in commercial trucking, the ability to reduce emissions to near-zero levels while also delivering 3-5% fuel savings distinguishes SCR as one of the only emissions control technologies that are as good for business as it is for the environment.

SCR technology is designed to permit NOx reduction reactions to take place in an oxidizing atmosphere. It is called “selective” because it reduces NOx levels using ammonia as a reductant within a catalyst system. The reducing agent reacts with NOx to convert the pollutants into nitrogen, water, and tiny amounts of carbon dioxide (CO2) – natural elements common to the air we breathe every day. The reductant source is usually automotive-grade urea, otherwise known as DEF, which can be rapidly hydrolyzed to produce the oxidizing ammonia in the exhaust stream. SCR technology alone can achieve NOx reductions in excess of 90%.

Will DEF Reduce My Fuel Efficiency?

On the contrary: DEF has been proven to improve fuel efficiency and engine performance of diesel engines. In fact, diesel engines without DEF are slow and eventually stop running altogether.
