DEF Storage

In order to preserve the quality of Diesel Exhaust Fluid (DEF), it is important to understand the ins and outs of DEF storage. Drivers and operators of diesel vehicles need to practice good DEF storage and handling in order to ensure that they avoid contamination or misfueling, which can lead to issues within the Selective Catalytic Reduction technology. Read on to discover the simple facts of DEF storage and how you can ensure that you are following procedure!

DEF Specific Containers

Remember that DEF is a nonhazardous and non-flammable fluid. However, DEF storage is limited to specific DEF containers. This is for two reasons:

  1. The maximum level of impurities such as calcium, and various metals like iron, copper, zinc,  and aluminum, is specificied to be extremely low in order to ensure the reliable operation of the SCR system.
  2. DEF cannot be stored or handled in carbon steel, aluminum, copper, or zinc because it is corrosive to those materials.

This information is in correlation with the ISO 22241 standard, which governs the production, handling, and transportation of DEF. While DEF is not harmful to humans, it is extremely sensitive to chemical impurities. Often, DEF is more likely to be damaged by the materials it touches than to cause damage to equipment, but this contamination may cause the SCR system to malfunction. Therefore, DEF storage must be regulated carefully. The logical DEF storage solution is to ensure that the pumps and containers used for DEF are not used for any other fluids and are compatible with DEF transfer. This protects the quality of DEF as well as the sustainability of the SCR system.

Cleanliness

Another important aspect of DEF storage is to maintain clean conditions. DEF containers must be kept in clean conditions because any sort of foreign matter, whether liquid or solid, can contaminate the liquid. When filling a vehicle, diesel-owners should ensure that the DEF nozzle is clean. While protective clothing is not required, one might want to wear gloves when handling the fluid simply to protect the fluid from any contamination on your hands.

DEF Storage Styles

There are several ways to store DEF. DEF storage is offered in bottles or jugs, drums, totes, mini-bulk, and bulk. Victory Blue offers mini bulk to bulk solutions, from 500 gallons to 10,000 gallons. We are happy to find storage solutions in any range, however. We want to make sure that our customers understand the importance of DEF storage restrictions. For example, it’s important that DEF purchasers understand that DEF can freeze and can evaporate over time. However, so long as the cap of the DEF tank or storage container is securely closed, some evaporation can be prevented. As far as freezing is concerned, you can read more about what happens here.

If you have any questions about DEF storage or handling, please contact us. We’re happy to help everyone discover what it takes to store or handle DEF and we provide many different containers and DEF pumps to that end.
