What’s That – DEF Storage and Equipment

From hand-held jugs to gallons in bulk, you need the best equipment to ensure your diesel exhaust fluid (DEF) is both efficient and ready for use. Did you know there are several options for storing DEF, such as storage tanks, dispensing systems, transfer systems, with accessories like hoses and connectors? The journey of DEF systems has been marked by major technological advancements and milestones. Over the years, DEF systems and equipment have evolved into a pivotal component of fleet operations. In today’s “What’s That Wednesday,” we’re going to explore the storage innovations that shape DEF equipment systems.

A Break Down of DEF

Diesel Exhaust Fluid (DEF), a blend of 32.5% urea and 67.5% deionized water, plays an important role in reducing harmful emissions from diesel engines. When injected into the exhaust stream, DEF breaks down into ammonia and carbon dioxide. The ammonia then reacts with nitrogen oxides (NOx), transforming these pollutants into harmless nitrogen and water. This transformative process, known as Selective Catalytic Reduction (SCR), is necessary for meeting strict emission standards. Today, nearly all cars, trucks, SUVs, and buses rely on DEF to keep our air and environment cleaner. To maintain its productivity and environmental benefits, DEF must be stored properly to prevent contamination and degradation.

The Rise of Advanced DEF Equipment

The introduction of DEF in the mid-2000s brought on the need for specialized equipment to store and handle this chemical solution. Initially, the focus was on creating basic storage tanks and simple dispensing systems that could be easily integrated into existing diesel engine setups. These early systems were often rudimentary, with limited features and capabilities.

As the demand for DEF grew in the 2010s, establishing DEF as a commodity, the need for more durable storage solutions also increased. Manufacturers began differentiating their equipment based on corrosion resistance, size, and technology. These tanks, introduced around the same time, came in various sizes, from small portable containers to large bulk storage units, catering to different needs and scales of operation

The Importance of Proper DEF Storage

For most contractors, fleet managers, or anyone who relies on DEF, having an adequate supply is necessary to keep operations running smoothly. Large fleets typically rely on 300 to 600 gallons each week. To prevent the bypassing of environmentally safe devices, the Environmental Protection Agency (EPA) enforces regulations that emphasize the importance of maintaining an adequate supply of Diesel Exhaust Fluid (DEF).

DEF is distributed in multiple ways, including package units, jugs, and Intermediate Bulk Containers (IBC) totes. While these remain the common storage options, there are numerous dispensing systems, storage solutions, and additional accessories available to enhance DEF storage. Having the right equipment and maintaining it properly will help avoid potential operational disruptions—running out of DEF can be even more problematic than running out of diesel fuel. If warning lights are ignored and the machine is allowed to derate or stop, it could require a technician to reset the machine’s electronic control module. By that point, simply refilling the DEF tank won’t resolve the issue; a reset would be necessary.

DEF Storage Solutions

Typically, you can find DEF on the shelf at your local auto shop, but that’s not sufficient for around-the-clock, heavy-duty operations. Like fuel tanks, DEF storage can be large enough to accommodate bulk, on-site needs. Bulk DEF storage can hold up to 500 gallons of DEF or more, with some storage systems featuring cabinets and dispensing hoses. These bulk storage containers can be customized to fit on- or off-site operations. There are bulk DEF containers designed for remote locations, commercial sites, and rugged outdoor conditions.

Dispensing solutions can largely impact how efficiently you use DEF to meet your needs. There are numerous options for DEF dispensing systems and accessories that enhance DEF storage and usage:

• Commercial dispensers
• Dispense pedestals
• Hoses
• Automatic shutoff nozzles
• Dispense couplers
• DEF meters
