Thermal Imaging Inspections in Hampshire

Find out how our thermal imaging in Hampshire protect against fire and business downtime. Our Flir thermal imaging cameras can spot problems that cannot be seen. 

Do you like an easy life without any problems? Imagine what it would be like if you could detect problems before they occurred. Electrical and mechanical components frequently generate heat when a problem occurs. On the negative side heat cannot be seen with the naked eye and problems often go undetected. As a consequence, if left undiagnosed these components will eventually fail. However, we can see these problems for you with our thermal imaging cameras. As a result, we can detect hidden issues before they become a problem. Consequently, this allows potential problems to be dealt with before a fire or breakdown occurs. Consider how thermal imaging inspections could help your business.

What is Thermal Imaging?

Thermal Imaging cameras use an infrared detector to measure thousands of individual temperature points. These temperature points are then assigned a colour based on their temperature. For instance cooler colours like black and blue are assigned to colder temperatures and similarly colours such as yellow, orange and red to hotter temperatures. In this way we can paint a picture using colours and use it to diagnose various heat abnormalities and recognise thermal signatures.

How does Thermal Imaging work?

Thermal Imaging cameras use optical lenses to detect incoming infrared radiation which is subsequently processed and displayed as a thermographic picture called a thermogram. In contrast to a normal photograph, a thermogram contains radiometric data allowing it to be analysed to provide both qualitative and quantitative data. Our Thermal Imaging cameras measure and provide 76,800 unique temperature measurements in each thermal image. Analysis of these images can provide a wide range of information ranging from immediate risks together with areas that should be the focus for preventative maintenance.

Applications for Thermal Imaging Inspections

Distribution Boards

Thermal Imaging is ideally suited to detecting issues in distribution boards that traditional electrical fixed wiring inspections will not pick up. Overloaded circuits and loose high resistance connections are often detected.

Motors

Excess heat is bad for motors. As a result, for every 10 degrees centigrade that a motor operates above it’s rating , the lifetime of the insulation will decrease by 50%. Other issues that are frequently found are:

  • Overload
  • Winding Faults
  • Single Phasing
  • Blocked air vents
  • Bearing problems
  • Drive shaft misalignment

Trace Heating

Trace heating is commonly used around freezer doors to stop them freezing shut. Similarly it is also used as a method to stop water pipes from freezing and bursting in cold weather.  Thermal imaging cameras can easily detect whether the trace heating is in operation. In this particular example  we can see an emergency exit on a warehouse freezer store. It can clearly be seen that the trace heating has failed.

Bearing & Belt Tension Problems

Friction causes heat. This is something which is readily picked up by a thermal imaging camera. Problems that can be detected include lubrication problems, misalignment, wear and incorrect belt tensioning.

  • Incorrect belt tension
  • Bearing wear
  • Lubrication problems
  • Incorrect alignment

Case Studies from some of our Thermal Imaging inspections in Hampshire

Thermal Imaging of a main fuse head

This image shows a three phase fuse head with three fuse carriers. As can be seen the first fuse holder is considerably hotter than the other two which indicates a problem. Potential issues for this would likely be overloading on phase one or alternatively a defective connection inside the fuse holder. If left uncorrected this situation could progress to fire or failure of the electrical system.

Thermal Imaging of an Industrial Oven

In this example from a thermal imaging inspection in Hampshire we can see a large industrial oven situated in a factory. The thermal image reveals several issues that if left could  cause a fire or injury. The door seals have worn resulting in heat escape which will have a negative impact on energy efficiency. The insulation has become defective allowing heat to be transferred through to the external surface of the oven. In places the external temperature is nearly 115 degrees centigrade. This could cause an injury if accidentally touched. What about the wood leant against the left hand side and the boxes on the right hand side? These present potential fire risks.
