Predictive Maintenance Techniques

Vibration Analysis Condition Monitoring

Ultrasonic Analysis

  • Detects air, steam, and vacuum leaks with precision

  • Identifies early-stage mechanical wear and lubrication issues

  • Pinpoints electrical faults: arcing, tracking, and corona

  • Verifies steam trap and valve performance in real time

  • Enables safe, non-intrusive testing during operation

  • Backed by ISO 29821 standards with actionable reporting

Predictive Maintenance, Vibration

Vibration Analysis

  • Detects bearing wear, imbalance, misalignment, and looseness

  • Identifies mechanical faults before failure occurs

  • Monitors condition trends across motors, pumps, and gearboxes

  • Supports precision maintenance planning and root cause analysis

  • Reduces unplanned downtime and unnecessary part replacement

  • Compliant with ISO 10816 and ISO 20816 standards

Infrared Thermography

Infrared Thermography

  • Locates hot spots in electrical panels, motors, and drives
  • Detects overheating components, poor connections, and overloads
  • Identifies insulation failures and energy loss areas
  • Enables safe, non-contact inspection during operation
  • Helps prevent fires, breakdowns, and compliance violations
  • Performed in accordance with ISO 18434 and NFPA 70B
Motor Circuit Testing

Motor Circuit Analysis

  • Evaluates motor health without removing or disassembling equipment
  • Detects winding shorts, insulation breakdown, and rotor issues
  • Identifies faults missed by vibration or thermography alone
  • Useful for both de-energized and energized testing (varies by method)
  • Ideal for motors, generators, and transformers
  • Supports predictive failure planning and spare parts management
Power Quality

Power Quality Analysis

  • Monitors voltage, current, harmonics, and transients in real time

  • Detects imbalances, sags, surges, and harmonic distortion

  • Prevents damage to sensitive electronics and VFDs

  • Verifies system loading and utility power quality

  • Identifies root causes of nuisance trips and overheating

  • Supports compliance with IEEE 519 and energy efficiency initiatives

Leak Survey for Predictive Maintenance

Leak Surveys

  • Pinpoints compressed air, steam, gas, and vacuum leaks

  • Reduces wasted energy and compressor load

  • Identifies hard-to-access leaks using ultrasound

  • Generates prioritized leak repair lists with estimated loss per leak

  • Supports sustainability, cost savings, and rebate qualification

  • Fast ROI—often within weeks of inspection

Oil Analysis

Oil Analysis

  • Detects wear particles, contaminants, and lubricant degradation

  • Tracks component wear through metal content and particle shape

  • Identifies coolant leaks, fuel dilution, and oxidation

  • Enables optimized oil change intervals and reduced waste

  • Supports failure prevention in gearboxes, hydraulics, and engines

  • Can be trended over time for precise condition monitoring

Laser Shaft Alignment

Laser Shaft Alignment

  • Prevents and corrects misalignment in rotating machinery

  • Reduces vibration, heat, and coupling/bearing wear

  • Improves energy efficiency and machine life

  • Faster and more accurate than dial indicators

  • Verifies alignment within manufacturer tolerances

  • Essential for motors, pumps, fans, and gearboxes
