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.

Discover the four delta-Ts that define data center cooling efficiency and how measuring all of them can cut energy costs by up to 40%. Learn how Purkay Labs’ AUDIT-BUDDY delivers fast, rack-level thermal insights without permanent infrastructure.

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

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.
