The Western Sydney Airport construction was awarded as a joint venture for contrators. As part of this Hansons were enagged to provide concrete for one of the main contractors. Hansons required a temporary chiller set up at their Prestons batching plant to maintain water temperature for concrete mixing.
Active Air provided a complete chiller solution, with a 500kw chiller, heate exchanger, pump and buffer tank. As the power onsite was limited Active Air also provided a 500kva generator and electrical distribution to power the chiller plant. The system provided was completely stand alone.
During the summer months it is important to maintain the water temperature to ensure that the concrete cures to a high standard with no weakeness. To ensure that there were no issues with the temperature the concrete pours were conducted during the nights when the ambient temperature was cooler.
