Thermographic Inspection for Industrial Blowers
Specialized Thermographic Inspection programs for Industrial Blower Reliability & Maintenance.
Why it matters
Key Benefits
Hot Spot Identification
Infrared thermal imaging identifies abnormal heat patterns across industrial blowers surfaces that indicate developing faults in the rotary lobes or impeller, timing gears, bearings, and discharge silencer. Temperature anomalies are detected during normal operation without production interruption.
Electrical Connection Integrity
Thermographic surveys of electrical terminations and connections serving industrial blowers identify high-resistance joints before they cause arcing, fires, or protective device trips. This is especially critical for connections carrying full load current.
Thermal Profile Baselining
Establishing thermal baselines for industrial blowers under normal operating conditions enables rapid detection of deviations. Comparative analysis between identical units identifies underperforming equipment and prioritizes maintenance resources.
Context
Challenge & Approach
The Reliability Challenge
PD blower bearing temperatures are affected by both mechanical condition and compression heat conducted through the rotor shafts. Discharge temperatures on PD blowers vary with pressure ratio and inlet conditions, requiring process data correlation for condition assessment. Timing gear housing temperatures reflect both gear condition and oil circulation adequacy. Belt or coupling guard enclosures may prevent direct thermal imaging of drive components. Blower silencer and inlet filter condition affects both blower performance and thermal profile. Package-mounted blowers in enclosures develop elevated ambient temperatures that influence all component readings.
Our Approach
We image all bearing housings, timing gear covers, coupling or belt guard areas, discharge piping, silencer bodies, motor frames, and oil cooler components. Bearing temperatures are compared between drive-end and non-drive-end positions and between male and female rotor shafts (on PD blowers). Discharge temperature is measured and compared against expected values for the operating pressure ratio and inlet conditions. Timing gear housing thermal patterns indicate oil distribution and gear mesh condition. Motor frame imaging evaluates winding condition and cooling adequacy. Oil cooler thermal gradients identify fouling. Where IR-transmissive windows are installed on guards, coupling and belt temperatures are assessed. Reports include system thermal maps, component temperature comparisons, and maintenance recommendations.

Yes, industrial blowers must be operating under normal load conditions during thermographic inspection to generate meaningful thermal signatures. Equipment should be at steady-state operating temperature, typically after at least 30 minutes of operation at normal load. Cold equipment will not reveal the thermal anomalies that indicate developing faults.
Modern infrared cameras provide temperature accuracy of plus or minus 2 degrees Celsius or 2 percent of reading. Emissivity corrections, reflected temperature compensation, and proper measurement distance are critical for accurate readings on industrial blowers surfaces. Polished or reflective metal surfaces require emissivity tape or coating for reliable measurements.
