Cooling problems in data centers rarely start with alarms. They usually appear first as small warning signs—uneven rack temperatures, rising fan speeds, unexplained hot spots, or cooling units working harder than expected. This guide outlines ten common indicators that airflow or cooling performance may be limited, helping operators recognize hidden thermal issues before they impact uptime.

Data center cooling is often described as “keeping the room cold,” but the real goal is much simpler: move heat away from servers efficiently. This guide explains how airflow actually works inside a data center, how Delta-T reveals cooling performance, and why airflow distribution often matters more than cooling capacity. Understanding the path from supply air to server inlet, exhaust, and return gives operators the foundation needed to diagnose cooling problems before they impact uptime.

This Thanksgiving, Purkay Labs gives thanks for the data center systems and people that keep things cool, efficient, and running 24/7.

A bank’s UPS room faced random battery failures. Using Purkay Labs’ Dynamic Heat Maps, operators discovered hidden hotspots and fixed the problem for good.

This Halloween, Purkay Labs busts five cooling and airflow myths that still haunt data centers — and shows how to keep your facility truly chill.

 With the rise of AI and the construction of high-wattage data centers, airflow management has become a critical concern—not just in the white space, but also in supporting infrastructure such as PDU rooms, UPS rooms, and battery rooms. This article highlights the importance of airflow management in these auxiliary spaces and outlines steps to take when overheating conditions arise.

Purkay Labs is heading to Data Center World in Washington, D.C. next week!

Our CEO, Indra Purkayastha, and CPO, Aheli Purkayastha, will be attending to connect with fellow data center professionals, explore new technologies, and talk all things airflow and cooling.

Learn key strategies for forecasting and managing cooling costs in data centers, including how to account for seasonal changes, energy price fluctuations, operational growth, and the benefits of investing in energy-efficient technologies. Discover smart budgeting practices that can help optimize cooling expenses while maintaining operational efficiency.

"Explore the vital role of "What If?" scenarios in safeguarding data center operations in our latest Keep Your Cool blog. Discover how strategic planning and predictive analysis can help you assess and enhance your cooling system's resilience without risking downtime."

Don’t allow recirculated air take down your Chillers. This week on Keep Your Cool, we will be exploring how recirculated air can significantly impact chiller efficiency and overall operational costs.

At Keep Your Cool, we often advocate for raising data center temperatures to improve efficiency and OpEx. However, as temperatures climb, so does the risk of heat-related illnesses for staff in hot aisles, exacerbated by high wattage servers, particularly those fueled by AI. Today, let's explore why measuring heat stress in these environments is crucial for both people and performance.

Gauging your cooling efficiency doesn’t need to be difficult. Today we’ll explore a simple metric - called the Uniformity Metric- and how you can use it to benchmark aisle efficiency.

Preventative Maintenance may seem like a “nice to do,” but should be should be the top of your to-do list. Today we’ll explore a real life case study tracking changes in a data center aisle.

How can you simplify managing your thermal environment? Use the Uniformity Metric to calculate how consistent your temperature, humidity or dew point distribution is across your aisles. a quick and effective way to gauge the effectiveness of temperature control strategies, identify potential issues, and optimize overall system performance

Efficient data center cooling is no longer a luxury but a necessity, impacting both energy costs and overall performance. Thermal Surveys are a crucial tool for optimizing your data center environment because they help evaluate your environment and identify any problem areas. Today, we’ll explore what is a thermal survey and the top ten reasons you want to consider conducting one yourself, or using a third party service.

Purkay Labs reflects on a year of achievements in 2023, highlighting the a new Thermal Survey Service, a new blog called “Keep Your Cool”, and some new user-friendly updates to our software. As always we were proud to sponsor several data center conferences, and are anticipating a year of continued innovation in 2024.

Introducing the our Thermal Survey Service, which helps to set a new benchmark for proactive and efficient data center management.

Purkay Labs, a trailblazer in thermal surveys for new and existing data centers, proudly showcased its commitment to innovation, leadership, and community engagement at three prominent 7x24 Exchange conferences this fall.

Do you have a HVAC maintenance routine in place? If not, it might be time to take action to ensure that you keep a suitable temperature and humidity level. Neglecting routine maintenance can lead to decreased efficiency, system failure, and costly downtime.
