About the Service
Thermovision Scanning Services
Thermovision scanning is a non-contact inspection method that uses an infrared thermal camera to capture temperature patterns across electrical and mechanical equipment. It helps maintenance teams identify unusual heating that may indicate loose connections, excessive resistance, overloading, phase imbalance, poor cooling, friction, or deteriorating components.
Sachu Technologies provides thermovision scanning services for industrial plants, commercial buildings, manufacturing units, utilities, warehouses, hospitals, data centres, and solar installations across India.
Where practical and safe, the inspection is performed while equipment operates under normal working conditions. This enables the thermal camera to record temperature variations under actual load. Our specialists review the captured thermal images, compare similar components, document abnormal patterns, and prepare a structured inspection report.
Thermovision scanning can support preventive and condition-based maintenance by helping teams locate equipment that may require further investigation. However, a thermal anomaly does not always confirm its exact cause. Load conditions, equipment design, ambient temperature, and relevant electrical or mechanical measurements must also be considered.

- Components requiring further investigation
Our Approach
Our Approach
1. Inspect
We review the equipment, operating conditions, inspection scope, accessibility, and site safety requirements.
2. Scan
Accessible equipment is scanned with an infrared thermal camera under representative operating conditions.
3. Measure
Thermal images, surface temperatures, load details, equipment information, and visible photographs are recorded.
4. Analyze
The collected information is reviewed to identify abnormal temperature differences and unusual thermal patterns.
5. Report
We prepare a structured report containing thermal images, visible photographs, recorded temperatures, observations, and equipment details.
6. Recommend
The findings are presented to help the maintenance team prioritize further testing, monitoring, or corrective action.
Frequently Asked Questions
Thermovision scanning uses an infrared thermal camera to detect and display temperature patterns on the surface of electrical, mechanical, and process equipment.
The terms are often used for similar infrared inspection methods. Both involve capturing and analysing thermal patterns, although the exact inspection scope may differ by application.
It can help identify unusual heating associated with loose connections, overloads, high resistance, electrical imbalance, friction, poor cooling, and insulation-related conditions.
No. It identifies surface temperature differences. Faults that do not create a measurable thermal pattern may require other electrical or mechanical tests.
