Project refrigerant and was pre-manufactured on a galvanised frame . The galvanised frame for the critical charged installation was chosen for its corrosion resistance . Thereafter , 33 % propylene glycol mixture was added to the system to supply an operating water temperature of -5 ° C .
Coldfact , as the main contractor , oversaw the entire installation , while each subcontractor specialised in specific aspects like the design , refrigeration system , evaporative condenser , and control system .
The SCADA ( Supervisory Control and Data Acquisition ) control system by HCS Automation and Control provides centralised monitoring and control , enhancing system efficiency . The main distribution board by Industrial Motor Control manages power distribution for various components . Procontrol ' s role involves water treatment , which is crucial for maintaining the efficiency and lifespan of the evaporative condenser . RACA
