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.
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
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
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.
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.
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.
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)
Pinpoints root causes of recurring or abnormal vibrations
Prevents long-term mechanical fatigue and component failure
Enhances chiller system stability and energy performance
Reduces downtime and noise levels
Optimizes performance of systems with VFD-driven motors
Experts in chiller diagnostics and advanced vibration analytics
Use of state-of-the-art sensors and harmonic analysis software
Experience with resonance, VFD interference, and structural vibration
Precise reporting with clear, actionable solutions
Full support including corrections, repairs, and monitoring plans
Harmonic vibrations can silently reduce the performance and lifespan of your air-cooled chiller. With EKG M&E Sdn Bhd’s harmonic vibration analysis, you get ahead of unseen issues before they become costly problems.
