A customer called today asking for Diesel Exhaust Fluid today

Sure enough > it's for the newer diesels.. http://www.factsaboutscr.com/def/default.aspx Hi, I work with Air1 (a Diesel Exhaust Fluid manufacturer) which supplies DEF to the US. It's not just any urea but a high spec urea solution which is used to reduce NOx emissions in high powered diesel engines. If normal grade urea is used instead of DEF, the system will suffer as its not pure enough. DEF can be bought in different pack sizes from 1 gallon to bulk storage. When on the road, usually you can fill up at DEF retail outlets, local fuel/lubricant distributor as well as a local dealership. We see that a lot of people have questions about DEF, and are helping to answer them. If there are other DEF questions, or extra information needed, I'm happy to answer any questions on this topic. |

DEF is a high spec urea solution which means that it is made from high purity urea and demineralised water. The specification is defined in an internationally recognized ISO standard, which means that there are strict limits for acceptable levels of potential impurities, and accurate concentration of the DEF solution. If it’s not within this specification, it is not DEF. The reason for it being of a specific high standard is due to it being injected through the SCR system. If low grade urea and tap water is used it could cause SCR catalyst deactivation, and system breakdown. |
