Industrial Thermography for Manufacturing Plants in the GTA

Why Industrial Thermography Is Done During Production

Industrial thermography is done while the plant is running because heat at a faulty joint depends on current, and a production line at full output is when your distribution equipment carries its real working load. Scan the same plant on a quiet weekend and many defects simply will not show.

Electrical heating at a bad joint scales with current squared. Double the amps through a corroded lug and the heat it makes roughly quadruples. That is why a bus plug feeding a stopped extruder can look normal on Saturday and run dangerously hot on Tuesday morning. Our thermographers plan the route around your production schedule, record the measured current at each finding, and note what the line was doing at the time, so that next year's survey compares like with like.

Standards guidance for electrical thermography asks that circuit loading during the scan be documented, and where normal load cannot be reached, that the reduced load be recorded with the results. In practice we would rather come back during a full shift than hand you a report built on idle equipment.

If you are new to the method itself, our infrared electrical thermography page explains how heat is measured and rated. This page covers how we run a survey inside a working plant.

What a Thermographic Survey of a Manufacturing Plant Covers

A thermographic survey of a manufacturing plant follows power from the utility service down to the machines: incoming switchgear, transformers, distribution, motor control and the larger process loads. The route is agreed with your maintenance lead before the visit so nothing critical is skipped.

Welders, induction heaters, compressors, chillers, dust collectors and battery charging rooms are added when they are part of your critical path. We also note anything we find that is not electrical heat but still affects the gear, such as a blocked ventilation louvre or a panel used as a shelf.

Planning a Plant Survey Around Shifts and Lockouts

We plan a plant survey with your maintenance and production leads so the scan happens under load, without unplanned stops, and inside your site safety rules. No shutdown is needed for the scan; outages come later, for repairs, on your timeline.

• Site orientation and permits. Our crew completes your orientation and works under your permit system. Opening energized enclosures is assessed under CSA Z462, and where a live part cannot practically be isolated, Regulation 851 obliges the use of rubber gloves, mats, shields and safe procedures.
• Escort and access. A plant contact who knows which buckets feed which machines makes the survey faster and the report more useful.
• Hygiene and clean areas. In food and pharmaceutical plants we follow your gowning, glass and sanitation rules, and schedule around washdowns. See food and beverage processing for that sector.
• Restricted enclosures. Some gear cannot be opened while energized at an acceptable risk level. Those items are listed in the report with the reason, and we can recommend infrared windows for future scans.
• Shift coverage. Multi-shift plants can be scanned during a day shift or split across shifts so every department is seen at representative load.

We share a short findings summary with your contact before leaving the site each day, so production can react to anything urgent the same shift.

Setting Scan Frequency for Dusty, Hot or Critical Plant Areas

Plant areas with heavy dust, heat, moisture, vibration or corrosive air, or equipment whose failure stops production, usually justify a six-month scan; cleaner and less critical areas can stay on twelve months. That split follows the equipment condition assessment in NFPA 70B, whose 2023 edition sets thermography at 12 months for Condition 1 and 2 equipment and 6 months for Condition 3.

These are starting proposals, not fixed rules. The final cycle depends on your gear, manufacturer guidance and your own downtime costs. NFPA 70B is a US document adopted in Ontario by contract or insurer request; the Canadian maintenance standard, CSA Z463, frames how we write the overall program, and ANSI/NETA MTS (2023 edition), whose maintenance tests include infrared inspection, governs how each survey is performed and reported. For the full maintenance side, see factory electrical maintenance.

Trending Thermal Results From One Survey to the Next

A single survey shows today's hot spots; repeated surveys show which equipment is getting worse. Trending is where industrial thermography pays back, because a connection rising a few degrees each cycle can be fixed in a planned outage long before it fails.

To make trending possible we tie every image to a fixed equipment ID, shoot from a consistent position, and record load and ambient each time. The report carries forward last survey's readings next to this survey's, so your planner can see at a glance whether a repaired point stayed cool and whether a watch-list item is creeping up.

Trend data also feeds bigger decisions: which MCC lineup to replace first, whether a transformer is being run too close to its rating, and which areas need a shorter scan cycle. That work belongs to predictive electrical maintenance and electrical asset management, and thermography is one of the strongest inputs to both.

Turning Plant Hot Spots Into Planned Shutdown Work

Each hot spot in the report becomes a work item with a priority, an estimated outage need and the parts likely required, so your planner can group repairs into the next scheduled shutdown instead of reacting to failures. Urgent items are handled sooner.

1. Group by outage. Findings on the same bus, MCC or feeder are grouped so one isolation fixes several.
2. Prepare parts. We list likely parts, such as lugs, contactors, fuse holders or overload blocks, so the shutdown is not spent waiting for deliveries.
3. Repair under licence. As licensed electrical contractor ESA/ECRA #7014042, we carry out the work and file the ESA notification it needs.
4. Re-image under load. After restart, the repaired points are scanned again to confirm the temperature rise has gone.

Some findings point to deeper problems. A contactor that keeps overheating may need motor electrical testing on the load it serves; recurring heat in a lineup is a reason for full MCC maintenance; and hot breaker connections in the main gear often lead to switchgear maintenance with torque checks and cleaning.

Sector Notes for Food, Warehouse and Heavy Process Plants

Each kind of plant puts different stress on its electrical gear, so the survey route and the findings we watch for shift with the sector. A bakery, a cold storage warehouse and a metal stamping plant can share the same breaker brand and still fail in very different ways.

• Food and beverage. Washdown, steam and cleaning chemicals attack terminations and enclosure seals. We pay close attention to panels near wet zones, refrigeration compressor starters, and conveyor drives that cycle all day.
• Warehousing and distribution. Large lighting loads, conveyor and sortation controls, dock equipment and lift-truck battery chargers can push older distribution panels past what they were designed for as the building fills up. Scans during peak season catch the real load. Our warehouse and distribution page covers the wider maintenance picture.
• Metal, plastics and heavy process. Presses, extruders, injection moulding machines, induction heating and welding create heavy, fluctuating current and a lot of vibration. Terminal strips and lugs on these circuits work loose faster, and conductive dust adds tracking risk.
• Automotive and assembly suppliers. Just-in-time schedules mean any unplanned stop is expensive, which makes six-month surveys on the main feeders and MCCs easy to justify.

Tell us what you make and how the plant runs, and we will build the route around the equipment most likely to cause you trouble.

Plant Prequalification: COR, ISNetworld, Avetta and ComplyWorks

Many plants will only let a contractor on site once its safety program and insurance have been prequalified. KCS is COR certified through IHSA and is registered on ISNetworld, Avetta and ComplyWorks, so in most cases your contractor management team can approve us without a new paper file.

In Ontario, COR is granted by IHSA, and plenty of owners make it a condition for contractors coming on site. Alongside it we provide a WSIB clearance certificate, proof of commercial insurance, and our ESA/ECRA contractor licence number for your vendor records. Our thermographers are certified at Level II or higher, which your reliability engineer may also want on file.

If your plant uses a different prequalification platform or its own questionnaire, send it over and we will complete it before the first visit.

Plant Thermography Across GTA Industrial Areas

We survey manufacturing, processing and distribution plants across the GTA and Ontario from our base in Aurora, York Region. That puts the dense plant districts west and north of Toronto within easy reach.

That includes plants in Brampton, Mississauga, Vaughan and Hamilton, as well as facilities further out across Ontario. For plants with several buildings or sites, we keep one equipment numbering scheme and one report format across every location so corporate engineering can compare sites directly.

Thermography also fits into broader plant support. Our manufacturing clients often combine annual or semi-annual surveys with electrical testing, breaker work and arc flash labelling, so one contractor carries the full electrical reliability picture.
