DRAKES GOODWOOD FOODLAND One of Drakes’ three new CO2 tr a n s c r i ti c a l s to re s is l o c a te d i n Wayville, an inner-southern suburb of Adelaide. T he store will be fully ser viced by a transcritical CO 2 plant and is scheduled to open in February 2018. Store name: Drakes – Goodwood Foodland Location: Goodwood Road, Wayville, SA No. of transcritical racks: 2 LT rack capacity: 34.884 kW LT operating temperatures: -28°C to -33°C No. of LT display cases: 12 MT rack capacity: 161.116 kW MT operating temperatures: -6°C to -10°C No. of MT display cases: 37 Case supplier: Arneg Contractor: AJ Baker

Soang believes the level of technological development of transcritical CO 2 systems simply made their adoption at that time too premature. He is nonetheless keen to stress that the issues they experienced did not take away from the fact that the system was amazingly efficient. Reflecting back, Soang says, "I've never forgotten how quick the pull-down was – and I'm talking about when we actually started the cases up. The power of that CO 2 transcritical system was able to reduce the temperature inside the cases so quickly”. "I had never seen anything like it before." Problems stemming from p o o r d e s i g n a n d te c h n o l o g y eve ntually led Soang to swap the system out, but ever since he has been convinced that CO 2 is the way forward. “In the end, I replaced the transcritical system and went back to the more traditional CO 2 cascade system,” Soang says.

“The [transcritical CO 2 system] was pioneering – so with it came issues,” he explains. “From what I've seen now, we're star ting to realise that maybe we were just ahead of the curve, that's all.”

THE RETURN OF TRANSCRITICAL Witnessing the potential of CO 2 at first hand convinced Soang to move forward with subcritical CO 2 cascade systems for the next ten years, building confidence and experience in using the technology along the way. “Once we got the confidence that the systems work, we were quite happy to roll them out one after the other.” Since 2007, Drakes has installed subcritical CO 2 cascade systems at 14 store locations. “When we first started with CO 2 and it was transcritical, it was a problem,” Soang admits. “ B u t f r o m t h a t d a y o n wa r d s , we've had no problems with the
