Many workplaces operate server rooms, data racks, or technical equipment that cannot easily be shut down for inspection. In these environments, traditional testing and maintenance checks are often postponed or avoided altogether.
Thermal imaging screening provides a non-intrusive way to identify abnormal heat patterns in live IT and electrical equipment, helping to highlight potential issues without powering systems down.
What Is Thermal Imaging Screening?
Thermal imaging screening uses a specialist thermal camera to observe surface temperature patterns across visible components of server racks and associated equipment.
By identifying areas that appear hotter than expected, this screening process can help highlight components that may require further investigation by an IT or maintenance team.
This service is advisory in nature and is designed to complement existing inspection and maintenance practices.
What the Service Can Help Identify
Thermal imaging screening may help identify:
- Overheating server components
- Hotspots within data racks
- Abnormally warm power supplies and PDUs
- Uneven heat distribution that may indicate loading or ventilation issues
- Areas that warrant further investigation or monitoring
What This Service Is — and Is Not
Important Note
This service is intended as a screening tool only.
- It highlights areas of abnormal heat
- It does not diagnose faults
- It does not replace shutdown maintenance or detailed inspection
Any anomalies identified should be assessed and addressed by the client’s IT, electrical, or maintenance provider.
This is not a diagnostic thermographic inspection and should not be considered a formal thermal survey.
What You Receive
Where agreed in advance, clients typically receive:
- Thermal images or short video clips of the server rack or equipment
- Basic visual annotations highlighting areas of interest
- A brief verbal or written summary of observations
Thermal footage can be shared promptly after the visit to allow rapid review by IT teams.
How Thermal Imaging Screening Fits with PAT Testing
Thermal imaging screening is often carried out alongside PAT testing, providing additional insight for equipment that must remain live and cannot be unplugged during inspection.
While it is not an alternative to a full shutdown, it enhances the standard visual inspection element of PAT testing for critical equipment.
Who Is This Service For?
This service is suitable for workplaces that operate live technical equipment such as:
- Offices with server rooms or data racks
- Sites with CCTV, access control, or communications equipment
- Facilities with AV, broadcast, or monitoring systems
- Environments where downtime is difficult or costly
If your server equipment rarely — or never — gets powered down, thermal imaging screening offers a practical additional check.
