Temperature sensors and BMS dashboards provide useful data, but they rarely show how cooling is actually performing across an entire data hall. This guide explains how operators verify cooling performance in live facilities using rack-level measurements, thermal surveys, airflow visualization, and resiliency testing. By understanding Delta-T patterns and airflow behavior, teams can uncover hidden hot spots, airflow imbalances, and cooling constraints before they impact uptime.

Learn how a data center used Purkay Labs' resiliency testing to assess their cooling system’s ability to maintain operations during failures. The tests provided valuable insights that improved their operational stability and informed strategic upgrades for long-term resilience.
