Cold Logic has supported ASC to address issues of end-of-life obsolescence for components in the commissary refrigeration and freezer systems in the current Collins Class sustainment and life extension program. This challenge, plus changed capacity requirements by the RAN were successfully addressed during a redesign and re-specification of major components. Cold Logic also supported ASC during qualification trials and the first-of-class install. The overall project has been deemed a success increasing the overall system efficiency with the system modifications to be deployed across the entire fleet of submarines over the next years. Currently Cold Logic is in discussions with ASC to address additional areas of improvement that were not part of the original scope of works, but were highlighted by Cold Logic during the initial design and install process.
