In 2025, Purkay Labs focused on making environmental data more practical and actionable for data center operators. From deeper Delta-T analysis to expanded monitoring beyond the white space, this year reinforced the importance of measuring the right spaces with the right data.

Learn how monitoring and improving Server Delta-T can enhance cooling efficiency, reduce energy waste, and prevent equipment failures in data centers.

This article explores how measuring and managing the temperature difference between supply air and server inlets can improve data center cooling efficiency, reduce energy costs, and enhance airflow management.

Learn how managing the temperature difference between server exhaust and CRAC/CRAH return air can enhance cooling efficiency, prevent energy waste, and improve data center airflow management.

This article explores how measuring and optimizing Delta-T across CRAC and CRAH units can improve data center cooling efficiency, reduce energy costs, and enhance airflow management.

In a data center, keeping the equipment cool is crucial to maintaining uptime and efficiency. But how do you know if your cooling system is working as it should? That’s where Delta-T comes in—a simple metric that helps you measure how well your cooling system is performing. In this article, we’ll explain Delta-T, break down the four types, and show you how managing airflow can boost your cooling efficiency.
