Purkay Labs provides on-site thermal assessments to help data centers and other mission-critical facilities optimize cooling, airflow, and energy efficiency. Whether you need quick diagnostics, long-term monitoring, or resiliency testing, our services are designed to ensure your facility operates at peak performance. Contact us to proceed
Thermal Assessments
Why Do You Need an On-Site Assessment?
Efficient cooling systems prevent downtime, reduce operational costs, and improve environmental sustainability. Our assessments give you the data you need to stay ahead of potential issues before they escalate.
On-Site Thermal Assessments
Find Out What Your Cooling is Actually Doing
Purkay Labs offers three assessment packages to answer a different cooling question. The right scope depends on what you’re trying to find out.
| Assessment | Best For | What You Get | Turnaround |
|---|---|---|---|
| Thermal Spot Check Quick Diagnostic | Something seems off and you need an answer now — hot spots, unexplained alarms, post-change uncertainty. |
|
3 days after on-site |
| Thermal Trace Root Cause | A recurring problem you can't catch — intermittent alarms, load-dependent behavior, no finding after multiple visits. |
|
5 days after collection |
| Thermal Proof Full Validation | Proving your cooling works — commissioning, CFD validation, density increases, setpoint changes, board-level review. |
|
7–10 days after on-site |

Our Services
Thermal Spot Check
"Something seems off. What's actually happening in my room right now?"
What We Do
We deploy portable monitoring equipment at the rack level and collect temperature and humidity data across the problem area. One focused engagement. Fast turnaround.
What You Get
- Rack-level heat maps (horizontal & vertical)
- Uniformity Score for assessed area
- Plain-English findings summary
- One recommendation per issue identified
- One-page executive memo
- Review call within two weeks of delivery
Good Fit If
- Your BMS flagged something but can't explain it
- A tenant or customer complained about temperature
- You made a change and want to confirm it didn't create a new problem
- You need documented evidence for an SLA dispute
- You have a visible hot spot that needs confirmation before acting
Thermal Trace
"This keeps happening and I can't figure out why."
What We Do
We monitor your room over a full operational cycle, capture how conditions change over time, and identify exactly when and where thresholds are crossed.
What You Get
- Extended monitoring — typically 24–48 hours
- Time-trend graphs for each stand location
- Dynamic heat maps over the monitoring period
- Annotated analysis: when, where, and why
- Root cause hypothesis with supporting data
- Corrective action recommendations
- One-page executive memo
Good Fit If
- Alarms clear before your team arrives
- The problem only appears at certain loads or times of day
- You've had multiple site visits with no finding
- You've already tried the obvious fixes and it came back
- You suspect load-dependent behavior but have no data to prove it
Thermal Proof
"I need to prove my cooling works — before something goes wrong."
What We Do
We design and run a full validation — multi-scenario, rack-level, documented against your benchmark or test protocol — and deliver findings you can present to anyone.
What You Get
- Multi-scenario, multi-stand deployment
- Quick Scan, Long Scan & Delta-T as required
- Delta-T calculations & resiliency metrics
- Raw data export (.CSV or Excel)
- Test-by-test summary with pass/fail or variance analysis
- Board-ready executive summary
- Virtual presentation of findings
Good Fit If
- You're commissioning a new facility or major retrofit
- You have a CFD model that needs real-world validation
- You're planning a density increase or setpoint change
- A board or customer review requires proof of cooling performance
- You inherited a facility and need a reliable baseline
Case Studies
What operators find when they actually look.
60 tons of excess cooling freed up. $10K saved in month one. A major CRAC design flaw caught before a Fortune 25 bank went live.
Here's what rack-level visibility actually uncovers.

Benefits
By design, Purkay Labs tools are completely standalone. There is no permanent installation or integration into the system. Our team will come in, deploy the stands, collect data and leave without any impact on the data center.
No Downtime & Installation
Whether you want to benchmark before & afters or conduct a full scale thermal mapping during an IST, the On-Site Assessment is completely customizable to your needs.
Custom Reports
Purkay Labs understands that labor is in short supply. Purkay Labs’ offers a special monitoring service where highly-trained Purkay Labs Team Members will come to your facility and conduct a full environmental audit.

FAQs
What is a thermal assessment?
1
A thermal assessment is a short, targeted study of temperature, airflow, and humidity inside your data center. We measure conditions at the rack level to understand how your cooling system is actually performing—beyond what design documents or high-level sensors suggest.
How long does a thermal assessment take?
2
Most projects run 1 to 7 days on site, depending on facility size, scope, and objectives. We focus on getting useful insight quickly, without disrupting operations.
What kinds of facilities do you work in?
3
We work across enterprise and corporate data centers, colocation facilities, legacy sites with evolving layouts, and hyperscale and high-density environments. New builds and decades-old facilities both benefit — often for different reasons.
Do we need to shut anything down or disrupt operations?
4
No. Our assessments are designed for live, operational environments. We work around production systems and coordinate closely with your team to minimize disruption.
What do we actually receive at the end of the project?
5
You’ll receive: Clear heat maps and trend data
Identification of thermal constraints and risk areas
Practical, prioritized recommendations
The goal is clarity—your team should know what to fix, what to monitor, and what’s working well.
What if we already suspect where the problem is?
6
That’s common—and useful.
We can target known pain points to confirm root causes, rule out false assumptions, or uncover contributing issues nearby.
How much does a thermal assessment cost?
7
Pricing depends on facility size, scope, and duration.
After a short scoping call, we provide a clear proposal—no surprise add-ons, no open-ended engagements.

A colo provider suspected a tenant was drawing too much cooling. Assessment proved the opposite — the tenant was significantly overcooling. SLA dispute resolved with data, not assumptions.
