Purity in DEF Delivery Diesel Exhaust Fluid—Why BlueDEF Is Different 1-800-323-5440 E-mail Contact@peakhd.
With the introduction of the latest Environmental Protection Agency emissions levels limits in 2010, diesel engine manufacturers turned to a new technology to clean up nitrogen oxides in the exhaust stream.
But to hasten the adoption of the cleaner and more fuel efficient diesel vehicles, various incentives were available in Europe that pulled the adoption of SCR forward to as early as 2006. The SCR technology actually goes back even further. It has been widely used in electrical power generation facilities to clean up smokestack emissions for decades. The Emissions Solution In Europe the reagent as the chemical solution is termed, is sold as Ad Blue.
medicinal grade urea manufacturing plant, or the de-ionized water can be added to the urea at a distribution plant to save the cost of shipping water along with the urea. Since the composition of the DEF is strictly controlled by the ISO standard, the solution should be guaranteed to be of the same quality across the board.
Each shipment comes with a laboratory certification that it meets the ISO specification and extraordinary care is taken in the chain of custody to the end consumer to ensure that whether the DEF is in one, two-and-a-half gallon jugs, drums or 275 or 330 gallon totes it is of the same guaranteed quality. This also applied to DEF that is delivered in bulk, with dedicated tank trucks hauling only DEF making the deliveries.
This can be avoided if the driver keeps an eye on the dash-mounted DEF gauge and heeds the various warnings built in to the DEF storage and supply system on board the vehicle. The fault code would also light up the check-engine light (or malfunction indicator lamp– MIL). In extreme cases the engine will go into a derate situation where the truck may have to go to a dealer for the fault to be corrected.
Despite the careful attention to inventories of DEF on hand and anticipated in future, maintenance managers report issues with orders not being fulfilled in time, presenting problems with getting trucks out on to the “ready line” to go in to service. So part of the due diligence in selecting a supplier is to verify the delivery performance.
