Waikiki Private Hospital required a major upgrade after their ageing 750kw chiller reached end of life, threatening critical operations including surgery, recovery, and clean rooms. Complete Refrigeration & Air delivered a full system replacement with upgraded controls, improved efficiency, and long-term asset planning for ongoing mechanical services.
The hospital’s main chiller had reached end of life, risking failure across vital areas such as surgery and recovery. This created high maintenance costs, inefficiency, and the risk of critical downtime.
Risk to operating theatres, recovery, and clean areas
Escalating maintenance costs and inefficiency
Frequent manual adjustments to temperature setpoints
The Solution
Complete Refrigeration & Air replaced the chiller with a new system, upgraded controls, and efficiency features. The project included asset planning and the first stage of a full hospital-wide mechanical services refit.
Installed new 750kw chiller with upgraded PLC controls
Added new water pumps, pipework, and insulated cladding
Additional refrigerant circuits to reduce power usage
Capital planning for AHU replacement and BMS system rollout
The Outcome
The new chiller and upgraded controls restored full system reliability across the Hospital’s clinical environments. Operating theatres, recovery areas and clean rooms are now maintained at required parameters without manual intervention. Energy efficiency has improved through the supplementary refrigerant circuits and the upgraded controls system, reducing peak power consumption and ongoing operating costs.
The hospital is supported by an ongoing commercial HVAC maintenance program managed by Complete Refrigeration & Air – covering planned servicing, asset tracking and priority emergency response across all mechanical services on site.
