diesel exhaust fluid

DEF is a fairly simple substance that consists of roughly one part urea and two parts of deionized, purified water. When pure DEF is injected into the exhaust of a diesel-burning vehicle, that water turns into vapor and exposes the highly reactive urea to the surrounding heat.

Making Arrangements to Provide High Quality DEF to Any Diesel Powered Fleet

Choosing the best possible source for diesel exhaust fluid has become a top priority for fleet managers and other transportation professionals all over the country. Many commercial vehicles are now required by law to make use of diesel exhaust fluid, or DEF, and failing to obtain supplies of sufficient quality and purity can quickly become costly.

Fortunately, there are some options to consider that are worthy of relying on with confidence. Programs like the BlueDEF service offered by PEAKHD make it easy to be sure that an entire fleet will never lack the top-quality DEF it needs.

How DEF Works and Why It Must Be Pure

DEF is a fairly simple substance that consists of roughly one part urea and two parts of deionized, purified water. When pure DEF is injected into the exhaust of a diesel-burning vehicle, that water turns into vapor and exposes the highly reactive urea to the surrounding heat.

This excess of thermal energy causes urea to break down into two constituent compounds, with ammonia being the more notable and significant. Volatile ammonia binds eagerly to nitrogen oxide found in the exhaust streams of diesel engines that are tuned to employ relatively lean fuel ratios.

This simple reaction removes from the exhaust a substance that would otherwise contribute to the formation of smog and other environmental problems. The process can only be sustained without trouble if the DEF added to a given diesel vehicle's exhaust system remains as pure as possible until the moment of introduction.

A Comprehensive Take on Supplying and Dispensing DEF

Unfortunately, few existing logistical systems are well equipped to handle DEF carefully enough to ensure that it will never become contaminated or be subjected to other quality reducing problems. That has left some fleet managers facing what seems like the almost impossible task of acquiring and dispensing the pure DEF needed to remain compliant with existing regulations.

Fortunately, specialized suppliers have taken on all the associated challenges and are now ready to manage and overcome them on behalf of their clients. By designing and maintaining transportation, storage, and dispensing systems that account for the unique nature of DEF at every step, they are able to ensure that their clients will never lack the supplies they need.

In almost every case, simply making use of such a service will prove to be the best way to ensure that a fleet will not lack this critically important resource. Because so many vehicles today need to have access to pure DEF by law, this is an option that is frequently welcome.
