Diesel Exhaust Fluid (DEF) plays an important role in the transport industry. Reducing NOx in an efficient manner, DEF offers significant environmental benefits – but there are a few considerations to keep in mind regarding DEF quality.
DEF is prone to contamination and very sensitive when exposed to chemical impurities. If impurities are present in the solution, it can lead to the catalyst in the selective catalytic reduction (SCR) system failing, resulting in the warranty being voided, increased DEF consumption, and potentially costly replacements of the entire SCR system.
The main source of DEF contaminants is often related to improper storage and handling practices. Here are four practices that can help you keep your DEF quality in tip-top shape:
- Safe Storage: DEF should be stored in stainless steel, coated carbon steel, or specific high-density plastic containers in temperature-controlled areas, away from direct sunlight.
- Dedicated Dispensers: Components of the dispensing system must be dedicated solely to DEF to avoid mixing with other substances.
- Clean Bottles or Funnels: To maintain purity, it’s important to use clean funnels or bottles exclusively for DEF and avoid refilling previously used containers.
- Regular Cleaning: Cleaning any dust or dirt around the DEF tank during refilling is recommended and will ensure your DEF is in good shape and proper to use.
With these four practices in mind, you can ensure your DEF remains in good working condition.
