The project brief was to remove 3 existing air-cooled chillers from the first floor chiller compound over two stages to maintain 50% of cooling throughout the Shopping Centre and to install 2 1900 kilowatt Powerpax chillers, chilled and condenser water pumps and 2 cooling towers in their place, along with the integration of a new control system all housed in a new plant room enclosure.
 
The 1st Stage required the decommissioning of the first 2 chillers and separating from the existing system to enable chiller 3 to operate. Once disconnected from the system, the chillers were then removed and the installation of the new plant began. This entailed the positioning of the new chiller, pumps and cooling tower and building 50% of the plant room enclosure. Once all the system was connected the new plant was changed over and operated for a period of 2 weeks before the chiller No 3 was decommissioned and removed to begin Stage two.
