One delicate issue for diesel-powered engines equipped with Selective Catalytic Reduction (SCR) is their sensitivity to contamination caused by faulty handling and storage of Diesel Exhaust Fluid (DEF). When they fail, they take a lot of time and money for repair, leading to significant delays in operations. Aside from ensuring that SCR vehicle users know how to handle DEF themselves, SCR vehicle fleet owners need to search for fueling products that dispense DEF safely.
There are a lot of dos and don’ts in the use of DEF. Practicing these points will ensure that SCR vehicles are working at their best and potential harm is avoided. Only use fueling products particularly designed for storing or dispensing DEF. The urea-based fluid is added to diesel exhaust in SCR engines to reduce nitrogen dioxide emissions which the U.S. Environmental Protection Agency (EPA) said contributes to smog, asthma, respiratory disease, and heart disease. DEF can cause dispensing equipment to clog outside its optimum temperature range of 12 to 86 degrees F. Although DEF is non-hazardous, it is important to select the proper equipment in handling it for longevity and efficiency of SCR vehicles.
Selecting dispensing equipment for DEF is essential. Look for a manufacturer whose designs use 100 percent ISO recognized DEF compatible materials and with parts that are UL listed or made with UL- recognized components. Such steps remove questions about product safety and reliability.
Husky Corporation offers two DEF dispensing nozzles that meet those rigorous standards. The Husky DEF Stainless Steel DEF nozzle and the DEF Polymer nozzle with stainless steel spout are manufactured and tested to handle the unique characteristics of DEF. They are also equipped with unique features such as the Flo-Stop® device, the automatic shut-off system, and the patented Streamshaper® that minimizes fluid splash-back. This line of fuel nozzles is the perfect solution for retail truck stops that dispense high volumes of the fluid for over-the-road trucking customers. And as the market for SCR engines continues to grow, they are also perfect for vehicle dealerships, repair shops, oil change facilities, fleet-service centers and other locations that regularly dispense DEF from bulk dispensers or above ground storage systems.
Husky provides the quality, safety, and reliability that addresses the sensitive nature of SCR systems, making it your ultimate choice in DEF dispensing equipment.
