The regulations on diesel emissions that were passed by the EPA (Environmental Protection Agency) back in 2010 have, no doubt, affected the commercial trucking industry. While these changes are positive, they did create a need for the use of a new products and procedures. Now this same effect looks to create a similar reaction in the construction and agricultural industries.
2014: A Year for DEF
If you read the last article we published on this topic, then you’ll know all about the new plans for selective catalytic reduction (SCR) systems. As of this year, SCR systems are required in all off-highway vehicles. A vast majority of the diesel vehicles that fall under this distinction belong to three primary industries: mining, construction, and agriculture.
This new regulation on diesel emission management has created the need for DEF (diesel exhaust fluid) in vehicles beyond the common commercial truck. Now backhoes, tractors, dump trucks, combines, large generators, bulldozers, and myriad of other equipment and vehicles have to use SCR systems requiring DEF.
With the higher demand of DEF and the need to keep large quantities on hand, construction, mining, and agricultural companies have to learn and implement all the best practices associated with DEF. For example, DEF has limitations when it comes to proper storage.
DEF is a non-hazardous, liquid material used in SCR systems to minimize toxic emissions from diesel engines. When in storage and transportation, however, this liquid needs to be kept away from possible contaminants and at the proper temperature to ensure it maintains its usual shelf life. The ideal temperature for DEF is above freezing. Since DEF is most often stored outdoors in tanks and vats, this means that companies will need to harbor heating solutions for their DEF storage.
DEF Heating Solutions
Thankfully, third-party vendors have been providing solutions for DEF freeze protection nearly as long as DEF has been around. The proper solution for DEF freeze protection should offer an even and consistent distribution of heat to the entire surface area of the storage unit. This will ensure that your DEF isn’t overheated in one spot while being under heated in another. After all, DEF should never be over 86° F, or its characteristics could be compromised.
Additionally, you need a solution that will fit the common DEF storage unit, both insulating and heating at the same time. Thermostatic controls are also important, allowing you to set the proper temperature range without worrying about overheating. And ultimately, you need to work with a vendor that can offer a customized solution, should you ever need to cover and heat an uncommon storage unit.
