Thermal auditing for data centres

Every rack inlet, read twice — and graded against ASHRAE.

Our dual-sensor rig captures surface (IR) and air temperature together in one ultra-fast pass down the row, then grades every row against the ASHRAE 18–27 °C window — flagging both overheating and over-cooling — as a clear pass/fail you can hand to an auditor.

Two readings beat one guess.

A hot surface and a hot inlet are different problems. We measure both at once, so the report tells you which one you actually have — and where, to the metre.

Surface & air, together

Infrared catches hot equipment faces; the air sensor catches what the kit actually breathes in. Side by side, they separate a warm panel from a warm inlet.

Ultra-fast scanning

A full row in a single sweep — no rack-by-rack stops, no maintenance window. Hundreds of points per row, captured continuously as we walk the aisle.

ASHRAE verdict per row

Every row is graded against the ASHRAE 18–27 °C window — flagged if it runs too hot (overheating) or too cold (over-cooling), with the limiting reading printed right on the chart. Pass or fail, no interpretation needed.

Too hot costs uptime. Too cold costs money.

ASHRAE's recommended envelope has two edges, and a row can fall off either one. We grade against both — so the report catches the risk you can't afford and the spend you don't need.

Overheating · above 27 °C

The risk you can't afford

Inlets above the recommended ceiling push hardware past its safe envelope — thermal throttling, shortened equipment life, and a finding on any audit. We pinpoint which row, where along it, and by how much.

Over-cooling · below 18 °C

The spend you don't need

Inlets below 18 °C aren't a safety problem — they're a sign you're cooling harder than the equipment requires. That's energy and money leaving through the cooling units, and we flag the cold stretches worth dialling back.

The deliverable

What lands on your desk.

A clean, one-page profile per object — every rack row, both channels, graded. Here’s a sample row.

How it works

Three steps, one visit.

01 · SCAN

Walk the aisles

We move through each cold aisle once. The dual-sensor rig logs IR and air temperature continuously against position — live, with no equipment to power down.

02 · ANALYSE

Align & check

Readings are mapped to row length and tested against the ASHRAE recommended envelope, row by row, surfacing the warmest points and any cold over-cooled stretches.

03 · REPORT

Graded PDF

You receive an audit-ready report with a verdict and the numbers behind it for every row — plus a note on where you're spending cooling you don't need.

Why it matters

Proof, and a payback.

Compliance you can hand over

Graded against the ASHRAE recommended 18–27 °C band, per row, with the measured extremes behind every verdict. Evidence, not impressions.

Energy you can reclaim

Cold inlets flag over-cooling and bypass airflow — not just hotspots. The same scan that proves you're safe shows where you're overspending.

No maintenance window

Fast enough to run on a live floor. No rack-by-rack teardown, no scheduled downtime, no risk to running equipment.
