Mobile Automation has designed and installed the control system for the new DEF plant at Cummins Filtration Australia.
Cummins Filtration 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 to ensure no cross-contamination takes place between the two products.
The control system 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 performance standards and the regulatory standard.
To ensure that all products met compliance standards, the control system was integrated into Cummins’ existing Citect SCADA system to guarantee the next process could not start 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.
