Air-cooled chiller high-frequency vibration analysis

Air-Cooled Chiller High-Frequency Vibration Analysis | Detect Early Faults with EKG (Malaysia) Sdn Bhd

Why High-Frequency Vibration Analysis Is Critical

Detects early bearing degradation and microscopic flaws

Identifies issues like shaft rub, electrical arcing, or gear misalignment

Prevents unexpected equipment failure and downtime

Supports precision maintenance and lifecycle planning

Enhances system reliability, safety, and energy efficiency

Sources of High-Frequency Vibrations in Air-Cooled Chillers

• Compressor bearing wear or lubrication breakdown

• Fan motor electrical noise or unbalanced rotor

• Loose or damaged impellers

• VFD-related electrical interference

• Internal component impact or shaft misalignment

Our High-Frequency Vibration Analysis Process

• Sensor Installation and Data Acquisition
  We install ultra-sensitive piezoelectric accelerometers capable of capturing vibrations in the high-frequency range (above 1,000 Hz) on compressors, fan motors, and structural components.

• Envelope Analysis and Signal Processing
  Using envelope detection, FFT (Fast Fourier Transform), and time waveform analysis, we isolate high-frequency components that indicate:

  • Bearing flaws (inner/outer race damage, ball wear)

  • Impacts or frictional contact (shaft misalignment, loose parts)

  • Cavitation or turbulence within refrigerant circuits

• Root Cause Identification
  We pinpoint the exact source and nature of the high-frequency vibrations and assess the severity using baseline comparison with manufacturer specifications.

• Detailed Reporting and Maintenance Recommendations
  Our report includes:

  • High-frequency data plots and spectrum analysis

  • Identified faults with fault frequency correlation

  • Recommendations for bearing replacement, lubrication, realignment, or component balancing
