All our Electrical Installation Condition Reports also come with an included thermal imaging inspection for additional peace of mind and added value to our customers. Unlike many other providers our incorporated thermal imaging inspection will be completed by an electrical engineer with a minimum Level 2 certification in thermography, and, will only ever utilise high end camera equipment with minimum 640x480 resolution ensuring the highest of imaging quality.

The benefits of an infrared inspection

The benefits of an infrared inspection:

  • Inspections are complete without isolation of your supply, meaning we work to find the problems while you carry on regular business activities.
  • Completed frequently, identifies problems and allows for trend analysis to guarantee early defect detection, giving you time to plan any remediation before financial losses are incurred.
  • Our thermal inspections are significantly cheaper than other methods of inspection.
  • Only readily used defect detection for fire prevention, overloaded circuits are quickly identified.
  • Verifies re-connection of terminations are secure following a regular interval Electrical Installation Condition Report.
Commercial Electrical Thermal Imaging

Monitoring of electrical installations in commercial premises using thermal imaging is the safest and most cost effective form of maintenance possible to prevent future losses.

Studies carried out in the US show that for every $1 spent undertaking thermal imaging inspections, there is a $4 ROI (Return On Investment) from materials and labour costs saved fixing the problems identified before failure occurs. This study also proved that the ROI is actually $20 for each $1 spent if we consider the additional costs of losses in production, spoilage and extra expenses. However, the saving jumps to a staggering $60 ROI for each $1 spent where the inspection identifies defects that if left would have resulted in an electrical fire.

With around 3000 commercial fires reported in the UK to the HSE every year, this US study shows that the costs incurred could have not only prevented the losses and the inconvenience but would have also covered the inspection costs spanning a period of 60 years to prevent other occurrences also.

Using Thermal Imaging as your condition monitoring technique will also allow you to reduce the number of spares kept in stock as you will have advanced insight to potential problems giving time to procure parts and schedule the necessary downtime to complete repairs.

Electrical thermography is the best way of benchmarking new installations also and is advocated by insurance companies and many large manufactures of switchgear such as Schneider and Eaton.

Mechanical systems such as HVAC plant incorporate many different equipment types, from motors and pumps, to fans, bearings and many many more.

A plant inspection can monitor multiple areas of the systems quickly efficiently and with great accuracy to show areas of the plant where defects could cause failure.

The ability to inspect the plant without the need to shut down is cost effective to any business and can support maintenance regimes to ensure plant is not over or under maintained.

The benefits of an infrared inspection

  • Quickly and efficiently monitor and visually record changes in temperature for fault detection and maintenance of the system
  • Locate the source of airflow irregularities and draughts within rooms
  • Verify plant operation and control against control set points.
  • Locate duct leaks beneath insulation or in walls
  • Inspect for insulation efficiency and reduce energy losses.
  • Monitor effectiveness of duct work insulation
  • Monitor diffuser discharge and surface effect ceiling temperatures
  • Analyse Motors, Bearings, Sheaves and Belts without the need to isolate or shut down plant.
  • Maintain thermal data logs of all plant and equipment that allow for easy trend analysis from all inspections.
  • Assessment of Steam Traps, Lines, Radiators and Convectors.

Air Con/Refrigeration

Air Con/Refrigeration

  • Preventative Maintenance to locate early plant defects
  • Reduction of waste energy through identification of thermal leaks
  • Verify integrity of door seals or efficiency of thermal curtains
  • Inspect for insulation efficiency and reduce energy losses.
  • Quickly and easily locate Blocked Driers, Leaking Suction Valves, Overheating Fan Bearings, and Refrigerant Leaks.
Air Con/Refrigeration

These systems operate by relying on the transportation of heat energy from one location to another via the plant equipment. Monitoring the performance of this equipment is vital for ensuring continuous efficiency.

Loss of performance can result in major losses particularly in the food industry where product must be kept at specific temperatures.

TCL can monitor warehouses, commercial walk in fridge and freezer rooms, supermarket cabinets and cases including all associated plant. A loss of performance could result in massive costs in spoiled products.

Systems can be monitored for efficiency with the use of a thermal inspection and the highly visual data collected allows for engineers to effect early repairs to prevent against product loss and increased operating costs.

Air Con Full

Typically a refrigerator with a split door seal uses up to 11% more energy than an efficiently operating refrigerator with temperature losses reaching up to a staggering 20%.

Solar PV

Solar PV installations often assume a return on investment based on the continuous production of power over a period of 20 years. So what if there is a defect in the PV Array, damaged cells, a wrong connection, failed diodes or other defect preventing the production of power.

A thermal imaging inspection quickly shows visually what is happening at all panels no matter how large or small the installation, including where shading or defects are causing cells to consume energy rather than produce it.

From small corporate installations to large solar farms, we have the experience and equipment to monitor and report with clarity.

Panel manufactures who provide lifetime guaranteed equipment will be able to replace failed panels without cost, so an effective monitoring process is essential to maximising your return on investment. An annual inspection will ensure maximum profit on the investment of installing Solar PV.

New installations are also best checked by a professional thermographer as installation errors can be quickly and easily identified before full handover protecting both the contractor and the customer.

Solar PV

Commonly located defects:

  • Defective Bypass Diodes
  • Short circuits and failing connections
  • Penetration of moisture and/or dirt
  • Cracked cells or glass cracks
  • Failed or disconnected modules
  • Mismatched panels with different capacities
  • Loose contacts and wiring faults
  • Wear and tear.
  • Cell delamination

Refactory and Linings

  • Identify defects without shutting plant down
  • Trend and monitor problem sites over time
  • Invest in repair costs smarter
  • Schedule maintenance when needed


Refractory Linings

Heat retaining refractory linings can and will over time break down, when this break down occurs, heat is able to penetrate through to outer walls or surfaces. Dependent upon the purpose of the lining, this can either be a financial loss due to an inefficient system or worse a safety risk where external shells are quickly weakened through an increase of heat and internal pressures.

Regular monitoring of refractory linings will allow for trend analysis and an identification of breakdowns occurring. When early identification of defects are reported, the plant is able to be scheduled for shutdown and repair, eliminating costly unplanned downtime due to failure.

A thermal imaging inspection is able to identify the location and size of breakdowns in the lining, which is complete whilst normal operations continue, preventing a need to shut down and isolate plant so can be complete at any time.
