Thermography (Infrared Inspection)

Thermography uses infrared cameras to map surface temperatures, revealing developing faults that show up as heat — overloaded electrical connections, failing bearings, blocked steam traps, fouled heat exchangers and missing insulation. It is a fast, non-contact inspection and energy-survey technique.

How it works

An infrared camera images the heat radiated from surfaces, turning temperature differences into a picture. Because most developing mechanical and electrical faults generate abnormal heat, a thermal survey finds them without shutting equipment down — a hot connection, an overheating bearing, a stripe of missing insulation. It is widely used both for condition monitoring and for energy audits, where it quickly shows where heat is escaping.

What the data shows

A localised hot spot on an electrical connection flags a loose or corroded joint; a hot bearing housing flags developing bearing failure or poor lubrication; a cold steam trap flags one failed closed; a warm patch on a vessel flags missing or wet insulation.
