2025 Year in Review at Purkay Labs
2025 was a year of refinement at Purkay Labs. We placed less emphasis on expansion for expansion’s sake, and focused more on making environmental data clearer, more actionable, and easier to apply in real facilities.
Our work—across content, product development, and services—continued to center on a simple goal: helping operators understand what is actually happening in their spaces, before small issues become operational risks.
What YOU Read Most on Keep Your Cool
The most-read articles on Keep It Cool in 2025 shared a common theme: Delta-T still matters, and it’s still widely misunderstood.
Articles focused on server Delta-T, cooling unit Delta-T, and the relationship between server exhaust and return air consistently outperformed others. These pieces addressed practical questions operators face every day—whether cooling systems are working as intended, where inefficiencies exist, and how to diagnose problems using data that already exists in the facility.
Interest in alternative power sources also remained strong, particularly as operators consider how changing load profiles affect both cooling and electrical infrastructure.
These trends reinforced what we see in the field: operators want straightforward guidance tied directly to operational decisions, not abstract theory.

Conferences and Industry Engagement
In 2025, the Purkay Labs team attended 14 industry events. These included regional meetings, technical forums, and national conferences.
Highlights included returning to Data Center World in Washington, DC in April, and a speaking engagement at 7x24 Exchange International in San Antonio in October, where our CPO, Aheli Purkayastha, discussed her career path and operational lessons learned across product, engineering, and mission-critical environments.
Across these events, the conversations were consistent. Facilities are evolving, densities are increasing, and many monitoring strategies have not kept pace.
Product Updates: Focused Improvements
From a product perspective, 2025 was centered on internal improvements and usability.
A key update was the re-introduction of Dynamic Heat Maps. This capability allows users to visualize temperature, humidity, and dew point changes across a space and over time. Rather than relying on isolated point measurements, operators can now see spatial patterns and trends that reveal airflow issues, stratification, and emerging hot spots.
This functionality has been especially valuable during commissioning, load changes, and failure scenario testing.
Services: Expanding Beyond the White Space
Client projects in 2025 increasingly extended beyond traditional IT halls.
We supported assessments in UPS rooms, battery rooms, PSU rooms, and electrical rooms—spaces that are critical to uptime but often lightly instrumented. These environments frequently experience higher thermal stress, yet may only have one or two permanent sensors tied into a BMS.
Our work in these areas reinforced the same conclusion: environmental risk does not stop at the white space. Any powered, enclosed, mission-critical room requires sufficient airflow and temperature visibility to maintain reliability.
Conclusion
The takeaway from 2025 is straightforward.
If you want to manage an environment effectively, you need reliable temperature and humidity data in the places that matter—not just where it’s convenient to measure. Early visibility enables early intervention, whether the issue is inefficiency, airflow imbalance, or impending failure.
That principle applies across the data center, from server aisles to electrical infrastructure.
Purkay Labs remains focused on providing practical tools and services that help operators answer a simple question with confidence: Is my environment operating within safe limits—now, and over time?
