Air-Cooled Chiller Low-Frequency Vibration Detection – EKG M&E Sdn Bhd

At EKG M&E Sdn Bhd, we specialize in low-frequency vibration detection for air-cooled chillers, identifying hidden structural and mechanical issues that can affect long-term system stability and performance. Low-frequency vibrations—typically caused by imbalanced rotors, loose mounts, shaft misalignment, or structural resonance—can lead to increased wear, energy inefficiency, and even equipment failure if left undiagnosed.

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.
