Diesel Exhaust Fluid (DEF) is a must-have for modern diesel engines equipped with Selective Catalytic Reduction (SCR) systems. It’s a liquid that helps control emissions and keep things running smoothly.
In this article, we’ll cover everything you need to know about DEF in bulk, including storage and delivery options.
What is DEF and why is it important?
Diesel exhaust fluid, or DEF, is a mix of 32.5% urea and 67.5% de-ionized water. It’s an essential component in the selective catalytic reduction (SCR) systems that are used in diesel engines to lower the amount of nitrogen oxide (NOx) released into the atmosphere. Using SCR technology can also boost fuel efficiency by 4% to 11%.
It’s important to maintain proper DEF levels to avoid performance problems and keep your equipment warranty valid.
Bulk DEF Storage Solutions
If you buy DEF in bulk, it’s important to store it properly to maintain its quality.
Types of storage containers
DEF can be stored in containers ranging from small 2.5-gallon pails to large 3,000-gallon tanks. You can also find it in 55-gallon drums and 275- or 330-gallon totes.
Proper storage conditions
For the longest shelf life, DEF should be stored at temperatures between 40° and 80°F. DEF will freeze at 12°F, and freezing can damage it, so it’s important to keep it stored in a place where it won’t freeze.
Shelf life considerations
The shelf life of DEF varies based on the storage temperature. In general, you can expect it to last for 1 to 2 years. It’ll last for a year if the temperature stays between 10°F and 90°F, and it’ll last for 2 years if the temperature stays below 75°F.
DEF Delivery and Dispensing
If you use a lot of diesel exhaust fluid, you’ll need to think about the best way to get it and dispense it.
Delivery options
Companies like Sunoco LP offer DEF delivery. You can order it when you need it, schedule regular deliveries, or have them monitor your tank and keep it full.
Dispensing equipment
DEF pumps and other dispensing equipment are essential for transferring the fluid from a large container to your vehicle.
Consumption rates
In general, expect to use about 3% as much DEF as you do diesel fuel. One gallon of DEF should last for 300 to 500 miles.
Frequently Asked Questions
What is bulk DEF?
Bulk DEF simply refers to Diesel Exhaust Fluid purchased in large quantities, typically in containers like drums or totes, rather than smaller jugs. This is a more economical option for businesses and individuals who use a lot of DEF, like trucking companies or farmers with diesel-powered equipment.
What is DEF fuel used for?
Diesel Exhaust Fluid (DEF) is used in vehicles with Selective Catalytic Reduction (SCR) systems. It’s injected into the exhaust stream to break down harmful nitrogen oxides (NOx) into harmless nitrogen and water, reducing emissions and helping vehicles meet environmental regulations. It’s not actually “fuel,” but a crucial part of the emissions control system.
Does DEF fluid have urine in it?
No, DEF does not contain urine. While both DEF and urine contain urea, DEF is a specifically manufactured solution of high-purity urea and deionized water. Using urine in place of DEF could severely damage your vehicle’s SCR system. Stick to the real deal!
Why is a DEF delete illegal?
DEF deletes, which involve disabling the SCR system and preventing DEF injection, are illegal because they result in significantly higher emissions of harmful pollutants like NOx. These pollutants contribute to smog, acid rain, and respiratory problems, so tampering with emissions controls is a violation of environmental regulations and carries hefty penalties.
Wrapping Up
To keep your diesel vehicles running smoothly, it’s important to have a reliable source of DEF and a good way to store it. Choosing the right supplier and storage solutions can help you avoid interruptions in your operations.
