Dulux Merrifield

On the 17 March 2015 Dulux announced the construction of a new state-of-the-art $165M paint factory in Melbourne to supply Australia with water-based decorative paints.


CET Group was chosen as the process/mechanical consultant for this highly automated DULUX paint facility situated at Merrifield.


CET Group’s involvement began with concept development and costing inputs prior to project approval, through detailed design, technical construction assistance, joining the commissioning team, and validation assistance during initial production and during production output ramp-up.


It has been a long journey from developing the factory footprint and layout, to process throughput modelling, designing plants/units, producing ISO’s, specifying software and bench testing the code prior to site release.  Commissioning brought together the physical plant with the automation of SAP, MES, Batch and Process Control in a seamless manner.


Process Control, reducing manual interventions, consistency and robustness were key success factors and a number of new ideas were introduced as well as some innovation that was devised, trialled and successfully implemented.


CET Group is proud and grateful to play a role in this team orientated project.
