Diesel exhaust fluid (DEF) is an aqueous urea solution used as a consumable in selective catalytic reduction (SCR) in diesel engines to limit the release of nitrogen oxides into the atmosphere. Stored in diesel exhaust fluid storage tanks, DEF is a critical part of meeting the latest EPA specifications in the diesel emissions of cars and trucks.
Safe to Handle
DEF is a colorless, stable, non-flammable, non-toxic solution that poses no risk to people or animals if handled properly. If there’s a spill, simply use an absorbent material such as sand, spread it onto the solution, and shovel into an appropriate container for disposal.
Because DEF is so safe, it can be stored in bulk and provide peace of mind to you and your employees that there will always be enough DEF on hand to satisfy your business’s daily needs. And, since every company will have different requirements, BlueSky offers a variety of sizes of diesel exhaust storage tanks and diesel exhaust fluid transfer tanks- from one-gallon bottles to 2,000-gallon mini-bulk stations and stand-alone pumping stations- to meet whatever your demand.
Every step in the utilization of DEF, from processing to distribution, is carefully monitored for safety and reliability. Every DEF you purchase must be clearly labelled with certification from the American Petroleum Institute (API) that it meets strict ISO (International Organization for Standardization) requirements. Due to the strict standardization, it’s important that you not refill your DEF tanks on your own, but rely on the professional services of suppliers such as BlueSky for filled DEF tanks.
Operational in All Temperatures
It’s crucial your business operate in all kinds of weather. DEF is composed of 32.5% high-purity urea which freezes at 12°F. The solution is such that the urea and water freeze at the same rate, ensuring that the solution does not become diluted or over-concentrated. Under those circumstances, when the vehicle is operated normally, your SCR’s heating system returns the DEF to liquid form ASAP without any disruption in the operation of the vehicle.
Saves on Fuel Costs
Fleets equipped with SCR technology have seen their fuel efficiency improve from 4% to 11%. Besides further helping the environment, the increased MPG can save thousands of dollars in fuel costs.
The use of DEF safely stored in diesel exhaust fluid storage tanks is a vital part of the SCR technology creating a cleaner and more efficient transportation sector.
