Diesel Exhaust Fluid (DEF) is used by modern diesel vehicles and industrial equipment to cut nitrogen dioxide pollution from the exhaust. Not a fuel or a fuel additive, it’s used within Selective Catalytic Reduction systems, where it mixes with the exhaust stream during operation.
Aljon landfill compactors and scrap logger/balers use DEF, so understanding a bit about it is essential to getting the best performance from your equipment. One of the most important things to know is precisely how DEF is stored. Storing it properly protects your engine against untimely DEF quality faults and unwanted downtime.
Important Facts About DEF Storage for Owners and Operators
DEF fluid is highly sensitive to direct sunlight, accumulating condensation, and dust contamination. Any of these issues can render stored DEF unusable. To reduce risks to your equipment, always use DEF fluid that adheres to the ISO 22241 standard.
1. Where to Store DEF
DEF should always be stored in a cool, dry location away from direct sunlight. The ideal temperature range is 12°F to 86°F, which translates to -11°C to 30°C. Note that DEF can freeze in temperatures of 12°F or below. This doesn’t affect performance, but DEF should be stored using expandable containers in freezing temperatures.
2. How to Store DEF
DEF can be stored for up to one year under ideal climate conditions. It should be kept in dedicated containers, preferably stainless steel. While not toxic, DEF is corrosive to metals including carbon steel, aluminum, copper, and zinc. Avoid using any containers that might have been used to store other fluids.
3. Monitoring DEF Quality
DEF quality can be monitored using a digital refractometer. The refractometer measures the concentration of urea, a nitrogen-containing compound that breaks down into ammonia and enables a chemical conversion of nitrogen oxide into harmless nitrogen and water. An ideal concentration is between 32.5% and 37% urea.
