This guide is designed to help you understand how air actually moves through your facility. It focuses on the fundamentals—how cold air reaches servers, how hot air returns, and where that process breaks down in real environments. By the end, you should be able to spot common airflow issues like bypass and recirculation and understand why they matter before they show up as temperature problems.

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.

Intermittent temperature alarms in a PSU room with no obvious cause. Hidden airflow issues the BMS had missed entirely. Root cause identified and resolved.

As AI workloads surge, the power—and heat—inside every rack is growing fast. Here’s what that means for your facility, and how to get ahead of the cooling curve.

Many legacy data centers need to increase their IT Load but don’t have enough cooling capacity. This article examines a way to free up stranded capacity using the AUDIT-BUDDY system.

Data center environmental monitoring is essential for ensuring equipment and personnel safety by tracking and measuring factors such as temperature, humidity, and airflow. Using accurate sensors, like the AUDIT-BUDDY, regular checks and an alert system can prevent equipment failure, reduce downtime, and ensure optimal conditions.

Understanding the baseline conditions of a data center is crucial for its sustainability journey. Server Delta-T, measuring the temperature rise of cooling air at the server inlet and exhaust, is a key metric impacting server reliability and energy efficiency. Maintaining an optimal Delta-T, typically in the range of 10 to 20 degrees Fahrenheit, ensures efficient cooling. Learn more about the benefits of measuring your server delta-T here.

Are you aware that overcooling your data center can have negative consequences on both reliability and availability? In this article, we'll break down why keeping your data center temperature within Ashrae limits is crucial, and how Purkay Labs' thermal audits can help you optimize your cooling and save money on electricity.

Overcooling is a common issue in data centers that often goes unnoticed. It can waste energy, increase operating costs, and decrease the lifespan of your equipment. By using a tool, like the AUDIT-BUDDY and the Static Heat Map, you can identify areas of overcooling and adjust your cooling strategy to optimize energy efficiency and equipment performance. The data will help you to adjust your cooling strategy to save energy, reduce operating costs, and extend the lifespan of your equipment.

As the price of gas continues to rise across the globe, operators are searching for new methods, technologies and strategies to save on electricity costs. One simple solution is to use baseline your existing environment to identify simple airflow inefficiencies. With AUDIT-BUDDY, it’s simple to collect data and take action.
