The transfer system is a stainless steel truck unloading station, stainless steel piping, transfer pumps, and related control systems. Read on to find out everything you need to know about the DEF in your DEF system. It’s made from 32.5 urea and 67.5 de-ionized water. This additive is also called aqueous urea solution 32 or AUS 32. Tanks Direct provided a 2,500-gallon custom-built insulated and heated HDXLPE urea storage tank and transfer system to the Equinix Data Center in Ashburn, Va. It’s called DEF fuel or Diesel Exhaust Fluid (DEF). As urea becomes more widespread, the need for urea storage solutions has increased.įiberglass tanks and stainless steel pumps and piping, combined with proper installation corresponding with the climate of the location ensure that the Urea remains viable and that the storage unit which contains it will not corrode. Research suggests that the SCR process saves approximately 5% to 9% more fuel than an EGR engine. Urea’s popularity has increased not only because of federal regulations, but also due to its increased efficiency compared to exhaust gas recirculation (EGR) systems. The vaporized DEF and other exhaust gases enter a catalytic converter which contains the catalyst Nox, which reacts with the ammonia in the vaporized DEF and converts it into the more environmentally friendly compounds of nitrogen and water. When urea is injected into the exhaust stream of a vehicle or generator equipped with an SCR emission system, the heat of the exhaust causes it to decompose into ammonia and carbon dioxide.

Urea is made of 67.5% purified and deionized water and 32.5% urea and is found in vehicles and diesel generators as part of a process known as Selective Catalyst Reduction (SCR). The prevalence of diesel exhaust fluid (DEF) reflects efforts across various industries to meet new regulations for diesel exhaust fumes.
