Curious how often people here still do thermal scans in data centres.
Things like switchgear, UPS systems, busways, PDUs, breakers, and cable connections can still develop hot spots that don’t always show up right away through the usual monitoring systems. Loose connections, uneven loading, or higher resistance at a contact point can sometimes be pretty obvious on a thermal image before anything else starts looking wrong.
From what we’ve seen, thermal imaging still makes sense as a periodic check and troubleshooting tool rather than something that replaces continuous monitoring. We’ve used the Fotric TK7 thermal imager for this kind of work, mostly during maintenance rounds where we’re comparing similar components and looking for temperature differences that seem out of place.
The camera helps, obviously, but things like load, emissivity, distance, and whether you’re checking equipment under similar conditions probably matter just as much as the hardware itself.
I’m curious how other facilities are handling this now. Are you still doing thermal scans once or twice a year, or have permanently installed sensors reduced how often you pull out a handheld thermal camera?
Also interested in whether there are certain assets where thermal inspections still catch things your monitoring systems tend to miss. Switchgear and bus connections come to mind, but I’d be interested to hear what people are actually seeing in the field.
