Air-cooled chiller low-frequency vibration detection

Air-Cooled Chiller Low-Frequency Vibration Detection | Enhance Performance with EKG (Malaysia) Sdn Bhd

Why Low-Frequency Vibration Detection Is Important

• Uncovers slow-developing mechanical faults

• Detects imbalances or misalignments in rotating equipment

• Identifies loose connections or unstable mounts

• Prevents structural fatigue and noise issues

• Enhances system safety, reliability, and longevity

Common Causes of Low-Frequency Vibration

• Unbalanced fan blades or compressor rotors

• Improper motor or compressor alignment

• Worn or loose bearings and couplings

• Mounting frame resonance or baseplate movement

• External vibration transmission through structure or piping

Our Low-Frequency Vibration Detection Process

• Visual Inspection
  We examine the entire chiller structure and mechanical components for obvious signs of movement, wear, or instability.

• Sensor Deployment
  We install low-frequency accelerometers and velocity sensors on motors, compressors, fan bases, and support frames to detect low-hertz vibrations.

• Real-Time Monitoring and Analysis
  Using FFT (Fast Fourier Transform) and time-domain waveform analysis, we capture and assess vibration signals below 30 Hz to detect:

  • Rotor imbalance

  • Shaft misalignment

  • Frame resonance

  • Bearing looseness

• Root Cause Diagnosis
  Our engineers identify the exact source of low-frequency vibration and determine whether it's mechanical, structural, or environmental.

• Reporting and Recommendations
  You’ll receive a full report with:

  • Low-frequency vibration readings and severity ratings

  • Identified issues and affected components

  • Recommended corrective actions such as rebalancing, realignment, or structural reinforcement

Benefits of Low-Frequency Vibration Detection

• Prevents progressive equipment damage

• Reduces noise, wear, and vibration fatigue
