Harbour Town Premium Outlets, Chiller Plant Upgrade
Design and construct addition of a 2,250 kW water-cooled centrifugal chiller and new cooling tower to the existing central chilled water plant
Project story
QEG was engaged by Harbour Town Premium Outlets (via Colliers International Project Management) on a design-and-construct basis to add a third chiller to the south-west precinct central chilled water plant under a Major Works Agreement. The works comprised the supply and installation of a new 2,250 kW water-cooled centrifugal chiller with Danfoss Turbocor frictionless compressors, a dedicated BAC cooling tower mounted on a new structural platform, VSD-controlled chilled and condenser water pumps, pipework tie-ins to the existing chilled water headers, chemical dosing and side-stream filtration, a new dedicated MSSB and submains, and full integration with the existing Innotech BMS. Plant skids were prefabricated offsite in QEG's Brisbane facility and delivered as plug-and-play assemblies to minimise disruption to centre trading.
