AI and HPC workloads are pushing rack densities beyond the practical limits of air cooling, increasing the need for liquid-cooled capacity. This report from Airedale and STL Partners explores when retrofitting existing facilities makes sense and how operators can approach the transition.
The report explores:
- When liquid cooling retrofits become a strategic priority
- The costs, risks and complexities of retrofitting versus greenfield development
- How to identify assets that are suitable for retrofit
- Technical considerations for power, cooling, structural capacity and live-site operations
- A framework for assessing retrofit viability based on market demand, power constraints and facility type
- Practical recommendations for planning and executing a successful retrofit

It's time to really increase Data Centers Energy Efficiency. From what I hear and read roof top cooling consumes approx. 40% of the Data Centers electrical energy. All of the captured heat energy from the servers is wasted into the atmosphere. Then there is the issue of all the noise and air vibrations. Sidel CREN Inc. has a technology that can eliminate all of the rooftop cooling units and all the electricity and maintenance associated with these units. The Sidel TESS System is a device that takes in and stores the heat energy produced by the servers. Then as needed the TESS System converts the stored heat energy into electricity, to be used by the Data Center. Waste Is Not Waste If It Has A Purpose, and we have a purpose for the servers captured waste heat energy. www.SidelCREN.com
