Diesel Exhaust Fluid Systems: Reducing Emissions at Mission Critical sites

At Preferred, we are combining security and sustainable solutions at some of our highest security project sites, data centers and mission critical facilities, such as manufacturing centers.

A global pharmaceutical manufacturing company bought generators and commissioned the Preferred staff of experienced and qualified engineers to design this Diesel Exhaust Fluid (DEF) system, pumping 300 gallons (of ammonia) per hour, to be safely stored outside in locked stainless steel containers, which mitigates wear and tear on the pump set from rain and sun in any climate.

Made in the U.S.A., for secure, efficient, and sustainable data center and mission critical facilities, the DEF systems can reduce NOx Emissions in diesel generators and meet local emission requirements. DEF was developed to help keep heavy-duty diesel fueled machinery like boilers operating within federal emissions standards. At the chemical level, DEF is a combination of 67.5% de-ionized water and 32.5% urea that transforms harmful nitrous oxide emissions into harmless water and gas.

DEF isn’t actually a fuel additive, and it never comes in contact with diesel. Rather, it is stored in a separate tank and is pumped into the exhaust stream of diesel machinery to break down dangerous NOx emissions into safe nitrogen and water. This process is called Selective Catalytic Reduction (SCR).

Changes in EPA emission standards have required diesel burning machines to reduce their output, and SCR is the technology of choice for this purpose. As emission standards have continued to expand to include off-road vehicles, generators, and a variety of engines, the use of DEF is becoming more and more widespread.
