How To Store Diesel Exhaust Fluid (DEF) in the Summer

STORING DIESEL EXHAUST FLUID (DEF) IN THE SUMMER

Diesel Exhaust Fluid (DEF) is a reality these days if you’re running newer trucks in your fleet. How you store your DEF is an important consideration, especially with the summer months ahead of us. Cold weather doesn’t really affect DEF, but heat and prolonged exposure to sunlight certainly causes it to degrade. Now exactly how do you store def fluid in the summer time?

According to ISO22241, Diesel Exhaust Fluid (DEF) needs to be stored in a cool, dry place. Ideally storage temperatures should be between 12°F (11°C) and 86°F (30°C).

The reason of this recommendation is due to the fact that DEF can lose its potency if stored above 86°F for prolonged periods of time.

WHAT TO DO WHEN STORING DIESEL EXHAUST FLUID IN THE SUMMERTIME

So, what happens if you are filling your DEF tanks from a tote sitting outside in the heat this summer? The first thing to understand is that they are referencing the product temperature, NOT the outside air temperature. The product temperature will continually rise, and fall based on the surrounding air temperature, and will most likely not be held at a constant temperature. Is it a good idea to keep your DEF out of the Sun or inside? Absolutely, if you can, we would definitely recommend it.

IDEAL OUTDOOR TOTE STORAGE

The “real world” reality is that most fleets cycle through DEF regularly, so the product never has time to seriously degrade. Because of this, most fleets storing DEF outside don’t see an adverse impact to the product quality. We’ve listed some best practices here if you’re storing DEF during the summer.

  • Out of direct sunlight inside garages or warehouses
  • Place the tote under a canopy or shaded area
  • Keep caps and fittings securely tightened
  • Use a tote cover
