Control System Upgrades at Cummins Filtration at their new DEF Plant

Cummins Filtration Australia has commenced manufacture of Diesel Exhaust Fluid (DEF), a colourless urea-based chemical reactant, designed specifically to reduce Nox emissions in Selective Catalytic Reduction (SCR) systems.

The new plant has been set up inside a purpose built room to ensure the decanting takes place in pristine conditions, within a tightly controlled and filtered environment, ensuring no cross-contamination between the two products.

Mobile Electrics designed and installed the control system, which consisted of an Allen Bradley PLC and remote I/O over a DeviceNet network.

The DEF product requires stringent testing and analysis in order to meet both its performance standard and the regulatory standard. To ensure that all products complied, the control system integrated into Cummins existing Citect SCADA system to guarantee the next process could not be started until all tests were completed.

The new DEF production plant was officially opened by Joseph Saoud, President of Cummins Filtration in a ceremony at the Kilsyth plant, in February 2010.
