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.
