Mechanical Thermography 

Mechanical systems are the core of every facility. When they begin to fail, the warning signs are often invisible—until breakdown occurs. Infrared thermography allows early detection of developing mechanical issues while equipment remains in service, helping prevent costly downtime and unexpected failures.

At OI Infrared, we perform non-invasive mechanical inspections designed to identify abnormal heat patterns caused by friction, misalignment, electrical load issues, and mechanical wear.

What We Inspect

We evaluate a wide range of rotating and operating mechanical systems, including:

• Electric motors and motor bearings

• Pumps and pump assemblies

• Gearboxes and speed reducers

• Conveyor systems and drive assemblies

• Belts, pulleys, and coupling systems

• Fans and blowers

• Air handling units (AHUs)

• Compressor rooms and compressed air systems

Compressor Room Inspections

Compressor rooms are critical to facility operations and often one of the most energy-intensive and failure-prone areas in a building.

We inspect:

• Air compressors (rotary screw, reciprocating, centrifugal)

• Aftercoolers and intercoolers

• Air dryers and filtration systems

• Motor drive systems and belts

• Discharge piping and distribution headers

• Electrical connections feeding compressor systems

Infrared thermography helps identify:

• Overheating compressor heads or stages

• Bearing degradation in compressor motors

• Blocked or inefficient cooling systems

• Air leaks creating abnormal thermal signatures

• Electrical overload conditions in compressor panels

• Inefficiencies caused by restricted airflow or fouling

Early detection in compressor rooms can significantly reduce energy waste and prevent catastrophic system failure.

What Infrared Reveals

Thermal imaging allows us to detect developing mechanical issues before they become visible through vibration, noise, or performance loss, including:

• Bearing wear and lubrication failure

• Misalignment between rotating components

• Overloaded motors and electrical stress

• Belt slippage and tension imbalance

• Internal friction in gearboxes

• Restricted flow or failing steam traps

• Compressor inefficiencies and overheating components

Benefits of Mechanical Infrared Inspections

Regular infrared inspections help facilities:

• Prevent unexpected equipment failure

• Reduce downtime and production loss

• Extend mechanical system lifespan

• Lower maintenance and repair costs

• Improve energy efficiency—especially in compressor systems

• Support predictive maintenance programs

Our Approach

All inspections are performed while equipment is operating under normal load conditions to ensure accurate thermal analysis.

Our process includes:

1. On-site infrared scanning of mechanical systems

2. Identification of abnormal heat signatures

3. Documentation with infrared and visual comparisons

4. Severity classification and repair recommendations

5. Optional verification after corrective action

Reporting

You receive a clear, actionable report designed for maintenance teams and facility managers, including:

• Infrared and visible image comparisons

• Temperature differentials and findings

• Equipment location and system context

• Risk ranking and priority levels

• Maintenance recommendations and corrective actions

Why OI Infrared

We focus on real-world mechanical reliability—not just thermal images. Our inspections are built to support maintenance decisions that reduce downtime and protect critical infrastructure.
