The pre-fabricated chilled water skid arrives on site by truck for craning into position adjacent to the Landmark Place tower at 495 Boundary Street, Spring Hill.

Project story

QEG was engaged by the Landmark Place Body Corporate (CTS 15649, managed by Yule Strata) to replace four end-of-life DX air-handling units and their condensers with a central water-cooled chilled water plant serving the office and auditorium spaces at 495-499 Boundary Street, Spring Hill. Following an ROI analysis comparing the existing DX system against new DX and new water-cooled chilled water options, the Body Corporate selected the water-cooled chilled water solution which offered the strongest long-term operating-cost savings. QEG delivered the project on a design-and-construct basis, fabricating the chilled water plant offsite as a Quantum Cool Module skid (chiller, pumps, pipework, electrical and controls) to minimise on-site disruption and air-conditioning downtime during the changeover. The skid was craned into position adjacent to a new high-efficiency cooling tower, connected to two new and two refurbished chilled water AHUs, and commissioned with the Quantum Plant Manager BMS and remote-monitoring service.
