Donan Introduces Infrared Thermograph Technology to Increase Forensic Capabilities

Thermography is the use of infrared imaging and measurement to observe and assess thermal energy emitted from an object. Thermal energy is light that is not visible to the human eye because it is part of the electromagnetic spectrum we perceive as heat. The energy created by this heat encompasses radiation from gamma rays, x-rays, ultraviolet, and radio waves. The intensity of electromagnetic radiation is directly related to temperature. Much like an ordinary camera detects visible light, an infrared camera detects radiation and produces precise non-contact temperature measurements.

Materials containing moisture absorb and conduct heat and cold to a much greater degree than dry materials. For example, wet roof insulation absorbs heat while dry insulation reflects it. As a result, wet insulation will be much hotter than dry insulation, enabling the infrared camera to detect the difference.

A routine problem faced by property owners is moisture behind walls, over ceilings, and under floors, all of which can cause mold and infestation. Moisture and mold can destroy the structural integrity of building materials, but with thermograph technology there is a tool available to quickly detect these problems. With an infrared camera, you can see instantly what is wet and what is dry without the use of destructive testing or physically disassembling structures.

In electrical engineering studies, infrared camera technology is used for detecting overloaded circuits, faulty wiring, and loose electrical connections. Utility predictive maintenance programs often rely on infrared thermograph technology to avoid costly failures, prevent electrical fires, and improve service reliability.

Infrared technology can be used in mechanical engineering studies for detecting problems in motors, bearings in fans and compressors, refrigerant leaks, and blockages in HVAC components.

The use of an infrared camera can detect required maintenance on mechanical and electrical equipment, and walls and roofs with suspected moisture infiltration. By using this technology, money can be saved by reducing unscheduled downtime for repairs and/or failed equipment.

Additional Recommended Scenarios Where Thermograph Technology Can Help:

• Water damage inspections (flooding, broken water lines, plumbing leaks, equipment failures, roof leaks)
• Before acquiring real estate suspected of having hidden moisture
• Doors and windows suspected of leaking
• Energy audits
• Determining adequacy of insulation
• Wet areas in non-accessible crawlspaces
• Flat roof systems.
