Data Centers Closed-Loop Systems Draw on Experience – May, 12 2026
Southern PHC
In this article, Southern PHC examines how closed-loop hydronic systems are being scaled to meet rising data center cooling demands driven by AI and cloud growth. Mike Licastro emphasizes that while system scale has increased, the core principles of hydronics remain consistent, supporting efficient heat transfer in high-density environments. He highlights how closed-loop designs reduce water consumption through recirculation, while noting the importance of proper maintenance to sustain performance. The piece underscores how proven HVAC approaches are evolving to deliver more efficient and sustainable cooling for next-generation data centers.
