Hartford Steam Boiler Infrared thermography


Identifying and rectifying equipment issues before they become problems is a critical part of averting loss and maintaining uninterrupted service. Routine inspections and preventive maintenance can reduce failures, but they cannot reliably identify trouble spots.

More than meets the eye

An infrared survey can help keep small issues from becoming disasters. Repairing a loose connection– easily found with a thermographic scan – might cost only $100. If undetected, that same connection could result in a fire. That might mean injury, loss of life or damage that makes the whole building unfit for occupancy and shuts your business down.

Thermographic scans are a wise investment. Industry sources show that the monetary savings they produce can be 20 times as much as the initial cost of the survey. This does not include the potential losses due to damage associated with fire. 

How infrared thermography works

All electrical and mechanical equipment radiates heat. Infrared video cameras that are sensitive to this thermal radiation, detect and measure the temperature differences between surfaces. The cameras then convert the information and display it as an image visible to the human eye, allowing us to “see” a heat signature.


Abnormal or unexpected thermal patterns typically indicate a problem with the equipment, including conditions such as:

  • Loose electrical connections
  • Overloaded circuits or phases
  • Deteriorated or damaged insulation
  • Bearing failure
  • Insufficient lubrication
  • Steam leaks


These and other issues show up as hot spots that a trained professional can interpret to determine the likely cause and potential remedy.


For examples of actual thermal images showing real equipment issues, see Thermography in Action.
