Infrascan delivers routine thermal scanning services across Australia, helping facility managers and maintenance teams catch electrical hot spots before they turn into faults, fires, or unplanned shutdowns. Our thermographers scan your switchboards and equipment while they run, pinpoint the components heating up, and hand you a clear, engineer-backed report so you know exactly what to fix and when.

What Is Thermal Scanning: The Non-Invasive Diagnostic Technique

Thermal scanning is an inspection method that uses an infrared camera to read the surface temperature of your electrical equipment and flag anything running hotter than it should. When a connection loosens, a circuit overloads, or a component starts to fail, it gives off extra heat. That heat shows up on an infrared scan long before you would ever see, hear, or smell a problem.

​Also known as infrared thermal scanning, this is a live, non-contact inspection. We do not open your gear or shut it down. We scan while your equipment runs under its normal load, capture the thermal picture, and mark every hot spot that needs attention. The result is a fast, practical safety check that fits neatly into a routine maintenance schedule.
Where a full thermal imaging program is built around deep reporting, predictive maintenance planning, and compliance history, thermal scanning is the hands-on inspection at its heart: get on site, find the heat, and act on it.

What We Scan

Our thermographers carry out switchboard scanning and inspect a wide range of electrical assets across your facility, including:
  • Electrical switchboards: Main Distribution Boards and low-voltage equipment
  • Distribution panels and control systems
  • Circuit breakers, fuses, and busbars
  • Cable terminations and bolted connections
  • Motors, bearings, and gearboxes
  • Transformers and Power Factor Correction units
If a piece of equipment carries load and keeps your operation running, it is a candidate for a routine thermal scan. Not sure what to include? Our team can help you scope it when you request a quote.

Why Thermal Scanning Is a Smart Investment for Your Business

Using the best thermal imaging cameras, Infrascan delivers fast, non-invasive diagnostics that help you protect your assets, improve safety, and reduce costs. Whether you're conducting thermal scanning of switchboards, machinery, or electrical systems, the benefits are clear and measurable.

No Downtime

Thermal scanning is completely non-contact and performed while your equipment is running, no need to shut down operations. This is ideal for busy plants and facilities where uptime is critical.

Fast & Accurate Diagnostics

Our scans are conducted under normal load conditions, ensuring highly reliable and accurate results. We provide precise insights into component performance for rapid, informed decision-making.

Enhanced Safety

Identifying electrical faults early significantly reduces the risk of fire, equipment failure, and workplace accidents. Thermal scanning helps you maintain a safer, WHS-compliant environment.

Cost Savings

Avoid costly shutdowns and emergency repairs. Thermal imaging detects early signs of wear or failure, allowing for timely preventative maintenance that saves thousands in repair and replacement costs.

Boosted Productivity

By catching small issues before they escalate, thermal scanning supports strong predictive maintenance strategies. Fewer breakdowns mean smoother workflows and higher productivity across the board.

Affordable Protection

Compared to the financial impact of a plant shutdown or industrial accident, a thermal scan is a low-cost safeguard. It’s a smart, scalable solution for protecting your bottom line.

​How a Thermal Scan Works, Step by Step

We keep the process simple and low-disruption from booking to report. Here is what to expect:
  1. Book and scope. Tell us your site type, the boards and assets to be scanned, and any deadlines. We confirm an upfront quote with no hidden fees.
  2. On-site attendance. A licensed technician attends at an agreed time and works around your operations.
  3. Scan under load. Each board and asset is scanned while it runs under normal working conditions, so the readings reflect real performance.
  4. Hot spot detection. The thermographer identifies any component running hotter than its baseline and records the temperature difference.
  5. Grading. Every finding is graded by severity, so you can tell a monitor-it warning apart from an urgent repair.
  6. Report and sign-off. You receive a clear report with digital and thermal images, reviewed and signed off by our head-office engineer.

Services That Work Together

Thermal scanning works best as part of a complete electrical safety and compliance program. It pairs naturally with our other services:
  • Electrical Thermal Imaging: Build your scanning data into a full predictive maintenance and compliance program with detailed, audit-ready reporting.
  • RCD Testing (AS/NZS 3760): Confirm your residual current devices trip within the safe time limit to protect people from electric shock.
  • Test and Tag: Inspect and tag your portable appliances and leads for electrical safety, supporting your WHS obligations.

Frequently Asked Questions 

How often should thermal scanning be done?
Most commercial and industrial sites schedule a thermal scan once a year. Sites with heavy loads, critical equipment, or higher fire risk often move to biannual or quarterly scans. Many insurers and WHS programs expect a current scan report, so annual scanning is the common baseline. We can set up a routine scanning program to match your site's risk profile.
What does a thermal scan detect?
A scan detects components running hotter than they should, which usually points to loose or corroded connections, overloaded circuits, phase imbalance, failing breakers, or worn bearings and motors. Because heat is an early warning sign, a scan often finds developing faults weeks or months before they would cause a failure.
How long does it take to get the report?
Turnaround depends on the size of the scan, but most reports are prepared, reviewed, and signed off by our head-office engineer within a few business days. If you have an urgent deadline, such as an insurance renewal or an audit, ask about priority reporting when you book.
What happens if a fault is found?
Every hot spot is recorded in your report with its location, a severity grade, and a recommended repair timeframe. Urgent, high-priority findings are flagged clearly so you can act fast, while lower-priority items can be rolled into planned maintenance. The grading helps you prioritise repairs on genuine risk rather than guesswork.
