"PCU's DEF Dispensing System Right Solution"

The increased use and dispensing of UREA solution associated with Selective Catalytic Reduction (SCR) technology is driving demand for PCU fluid dispensing systems expertise. Many of the diesel engine and truck manufactures have chosen this thechnology in order to meet the 2010 EPA Requirements for 80% reduction in NOx over the 2007 emissions regulations. A SCR system injects a precise amount of diesel exhaust fluid (DEF) into the engine exhaust. The DEF combines with the NOx to form nitrogen and water.

PCU is currently well positioned with vehicle OEM's for all online filling equipment.  An existing customer that manufactures Class 8 trucks recently approached Production Control Units, Inc. (PCU) regarding filling the DEF tanks as the vehicle traveled on the assembly line. The manfacturer required the DEF machine to be capable of multiple fill volumes, and minimal operator involvement as well as verifing that the vehicle DEF tank was filled with the correct volume.

Working closely with the customer, it was determined that as the vehicle enters the workstation the Factory Information System (FIS) would communicate to the DEF dispensing machine the required volume to dispense into the vehicle. This would reduce the potential for operator error in volume selection. At this point the dispense console would commence pacing with the vehicle while simultaneously presenting the operator with the DEF fill tool. Once the operator inserts the fill tool into the DEF tank and presses the "start" pushbutton the machine monitors the amount of DEF being dispensed, automatically ceases dispensing flluid once the preset volume is achieved, and signals the operator the operation is complete. Once again, the machine communicates with the FIS the actual volume dispensed to the vehicle while the dispense console continues to pace with the vehicle until the operator removes the DEF fill tool and presses the "return to home" pushbutton.

Altogether, the application is not a new process to PCU, it just needs to be done right! The end user needs to consider that UREA is not a petrolem based product with its own unique characteristics, but rather a chemical based product where it is necessary to consider the potential for introducing fluid contaminates. To build on its experience and expertise by providing first fill DEF dispensing solutions for valued OEM customers, PCU is actively engaged in determining how best to support private fleet owner operators as well as commercial users with DEF dispensing systems in the field.
