Preventive mechanical maintenance

To maintain safety and reliability of machines, thermal imaging is used to identify problem components showing elevated stress levels caused by friction, misalignment, or internal damage. The high temperature resolution Testo thermal images will identify problem areas. For example, failing bearings will show clearly their location in the thermal image. Preventive maintenance can be scheduled then between the shifts to eliminate production downtime.

Electrical maintenance checks

Testo thermal cameras are used to spot overheating components in the low, medium, and high voltage systems. Thermal images help to locate parts that are either failing or exposed to imbalanced loads. Routine thermal scans are used to prevent outages and fire risks.

Location of structural defects in buildings

Testo thermal cameras are used for speedy detection of structural problems in the new and old buildings. Roof leaks are often located away from the dripping water, and hard to trace windows permeability, or the mold hazard areas come clear in thermal images. Testo thermal cameras are ideal to investigate heat loses, thermal bridges and missing insulation.

Precisely locating roof leaks

Damp areas in the roof structure, in particular in flat roofs, store the warmth from the sun for longer than intact areas. This means the roof structure cools unevenly in the evenings. Testo thermal imagers use these temperature differences to pinpoint the exact roof areas with trapped moisture or damaged insulation.

Troubleshooting HVAC installations

HVAC technicians save time finding silting blockage points in radiators using Testo thermal images. Thermal imaging helps to diagnose the AC, heating and ventilation systems bearings, pumps, tank levels, heat distribution issues, and find moisture collection points in the ventilation ducts.

Carrying out energy consultation

In building thermography, thermal imagers are ideal for quick, easy visualization of energy losses in the heating or air conditioning systems of buildings. Thanks to their high temperature resolution, Testo thermal imagers provide a detailed presentation of inadequate insulation and thermal bridges in the building shell. Thermal imagers are ideal for recording and documenting energy losses on outer windows and doors, roller blind casings, radiator niches, roof structures or the entire building shell. Comprehensive diagnosis can therefore be carried out to analyze energy efficiency, and structural improvement measures can be initiated.

Detailed energy consultancy, where the whole building shell is analyzed for its energy loss, effectively indicates further possibilities for energy saving.

Typical applications for the thermal imager:

  • Analyzing building shells
  • Easy to use in conjunction with Blower Door
