Fonterra's Hautapu plant underwent major process changes to increase its Whey Protein Concentrate (WPC) production capacity. Fonterra contracted Nemesys to supply the automation resources behind the upgrade, developing Level 2 Grafcet functional designs, PLC software, and HMI systems.
The work required modifications to the existing PCS software alongside significant physical installation changes across the WPC process plant.
The WPC process plant changes included:
Total I/O count: 1,000
By rebuilding the retentate, clarifier, and pressure control systems under upgraded PCS software, Nemesys helped lift WPC production capacity at Hautapu while modernising the plant's control architecture. The result is a higher-throughput process plant with improved flow control, pressure management, and water treatment.
