What We Do
We Help Operators See What Their Dashboards Can’t
Most data centers operate with some level of thermal uncertainty. Not because teams aren’t paying attention—but because airflow and thermal behavior don’t always show up clearly in fixed sensors, BMS dashboards, or trend reports.
Purkay Labs performs focused thermal assessments in live data center environments. We help operators understand how air is actually moving, where thermal margin exists, and where risk may be hiding—so decisions are based on data, not assumptions.
What is a Thermal Survey
A thermal assessment is a short-term, targeted measurement of real conditions in your white space.
It’s designed to answer practical questions operators care about:
Is cooling performing the way we think it is?
Where do we have margin—and where don’t we?
Are we compensating for unknowns by overcooling?
What changes over time have altered airflow behavior?
Our assessments are performed live, under real operating conditions, with no disruption to IT or facilities operations.
What It’s Not
This is just as important.
A Purkay Labs thermal assessment is:
Not permanent monitoring
Not CFD modeling detached from real-world conditions
Not a disruptive install or retrofit
Not a sales exercise for new cooling equipment
The goal isn’t to redesign your data center.
It’s to verify what you already have.
What We Measure
We focus on the environmental data that most directly reflects airflow and cooling behavior at the rack level.
This typically includes:
Temperature at multiple rack heights
Humidity where it matters most
Variability across aisles, rows, and zones
Patterns that indicate bypass airflow, recirculation, or imbalance
We intentionally keep the scope focused—enough data to reveal patterns, without creating noise.
What We Reveal
When viewed together, these measurements often highlight conditions that aren’t obvious in dashboards or alarms.
In live facilities, we commonly uncover:
Hotspots masked by limited sensor placement
Bypass airflow quietly reducing usable cooling capacity
Areas being overcooled to compensate for uncertainty
Zones operating closer to thermal limits than assumed
Drift caused by incremental changes over time
None of this implies poor operations.
It’s the natural result of environments evolving.
What You Get
We don’t deliver raw data dumps or abstract reports.
Operators receive:
Clear findings that show where risk and margin exist
Visuals that make airflow and thermal behavior easy to interpret
Practical recommendations that can be acted on immediately—or staged over time
Documentation that supports internal discussions with leadership, IT, or finance
The outcome is clarity, not complexity.
When This Is Useful
A thermal assessment is especially valuable when:
Rack densities have increased over time
Containment or airflow paths have been modified
Overcooling has become the default safety strategy
Legacy facilities support newer IT loads
Confidence is assumed—but not recently validated
If any of that sounds familiar, this assessment is likely useful.
How This Fits With Your Existing Systems
Thermal assessments are designed to complement, not replace, your existing systems.
They:
Provide independent validation of BMS or DCIM data
Highlight blind spots fixed sensors can’t cover
Offer a snapshot of real conditions under actual load
Think of it as a periodic verification—not another dashboard.
