Handling DEF from a Distributor Level

The care, custody, and handling of diesel exhaust fluid (DEF) is extremely important for the preservation of DEF quality. If DEF is not handled properly, the resulting problems can corrupt the DEF, which can lead to the following issues:

  • Detrimental Effects for the Selective Catalytic Reduction (SCR) Performance
  • Voiding of Vehicle Warranties
  • Premature Catalyst Deactivation
  • Fouling of Pre-filters and Injector Nozzles
  • Hundreds of dollars in damage

It’s easy to avoid these issues if the proper techniques for handling DEF are followed. To protect the SCR technology, distributors must review the proper techniques for handling DEF. The best way to maintain the purity of DEF is to ensure that ISO 22241 standards are met and by following a closed loop system. The closed, sealed, and secured container valve systems will help maintain the purity of DEF as it leaves the manufacturer’s facility and ends up with the end-user. Additionally, these closed loop systems provide tamper evidence and protect the user through DEF warranties.

Why A Closed System?

Closed systems enable distributors to ensure that the DEF was not tampered with, and has remained closed, sealed, and secured throughout the supply chain. Essentially, a closed system means that the container valve and coupler will automatically seal closed upon disconnect to ensure DEF purity and packaging integrity. Additionally, a tamper evident self-closing spring actuated integrated container valve system that remains closed, sealed, and secure throughout the service life of the container, from fill to dispense. Upon disconnect, the container valve and coupler automatically seal closed to ensure DEF purity and packaging integrity.

There are three things that you should do to maximize DEF purity and container reuse”

  1. Handle the container with care: This will maximize the container’s service life and minimize the costs associated with damaged containers. Keeping the container clean and dust free will help to reduce the potential of getting dust or dirt into the DEF. Even with a closed system, this is a good habit to develop.
  2. Check the serial number: Checking the serial number will help you to ensure that the container has not been tampered with. Additionally, you should periodically check the tamper evident wire seal serial number to match the number provided by the distributor, which will enable you to connect the container with the proper distributor.
  3. Perform routine maintenance: To maximize the equipment performance and DEF purity, you should periodically wipe the equipment down to remove any dust or debris. Handling DEF requires cleanliness.

Remember, a closed system DOES NOT involve a stinger/drum pump, or a probe/dip tube. A closed system is one that has an automatically sealing valve. Protect your DEF, protect your customers, and protect yourself by always using closed systems when handling DEF. Using the closed system will ensure that ISO 22241 standards are met, that DEF purity is maintained, and that any necessary tamper evidence is available.
