Air-Cooled Chiller Harmonic Vibration Analysis – EKG M&E Sdn Bhd

At EKG M&E Sdn Bhd, we offer expert harmonic vibration analysis services for air-cooled chillers, designed to detect and eliminate harmful vibration patterns that can lead to long-term mechanical wear, noise, and system inefficiencies. Harmonic vibrations—caused by electrical imbalances, mechanical resonance, or structural interactions—can go undetected during routine checks but often result in fatigue failures and energy loss if not addressed early.

Why Harmonic Vibration Analysis Is Important

• Identifies hidden, repetitive vibration patterns not visible in basic tests

• Prevents resonance-related damage to fans, compressors, and structural frames

• Improves system balance and operating efficiency

• Reduces noise, wear, and maintenance frequency

• Supports diagnostic and predictive maintenance programs

Common Causes of Harmonic Vibration

• Imbalanced rotating components (fans, motors, compressors)

• Electrical motor harmonics from VFDs (Variable Frequency Drives)

• Loose mounting structures amplifying vibration

• Alignment issues between motor and driven equipment

• Resonance frequency overlap between components

Our Harmonic Vibration Analysis Process

Sensor Deployment and Data Collection

We install high-precision vibration sensors on key components including the compressor, fan motor, structural frames, and mounting bases to collect detailed frequency and amplitude data.

Frequency Spectrum Analysis

Using FFT (Fast Fourier Transform) and order analysis, we separate normal mechanical vibrations from harmonic signals, identifying specific fault frequencies linked to particular components or operating conditions.

Phase and Resonance Identification

We determine whether the source of the vibration is mechanical or electrical, and check for resonant conditions that could amplify vibration and lead to premature failure.

Root Cause Diagnosis and Reporting

Our team delivers a full report that includes:

• Identified harmonic frequencies and their sources

• Severity levels and affected components

• Actionable recommendations for correction (e.g., realignment, dampening, motor tuning)

Benefits of Harmonic Vibration Analysis
