22 cze 2021 · Proper DEF storage enhances its shelf life. It must be stored in ISO-approved containers made from durable composite materials. Because DEF is corrosive to aluminum, storage containers made from stainless steel, polypropylene, and high-density polyethylene are appropriate options.
The shelf life of DEF is directly impacted by any oil or fuel contamination, so safe storage is critical for preventing early DEF expiration. Diesel exhaust fluid should be stored only in high-density polyethylene tanks and containers used exclusively for DEF.
17 gru 2023 · Implementing a combination of optimal storage practices, consistent monitoring, and proactive maintenance can significantly extend the shelf life of DEF and ensure its effectiveness in reducing emissions from diesel engines.
UNDER NO CIRCUMSTANCES SHOULD DEF BE KEPT FOR MORE THAN 3 YEARS. The table below shows shelf life for DEF continuously exposed to these temperatures for the entire period. Cycles where the maximum daily temperature is similar to what is shown below, will have longer shelf life than shown.
