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

At EKG M&E Sdn Bhd, we offer specialized dynamic vibration analysis services for air-cooled chillers, delivering real-time diagnostics of mechanical behavior during operation. Unlike static or routine checks, dynamic analysis captures how your system performs under actual load and environmental conditions, providing deeper insight into issues like imbalance, resonance, misalignment, and mechanical fatigue.

Why Dynamic Vibration Analysis Is Important

• Detects issues under real operating conditions

• Identifies problems that don't appear during idle or low-load states

• Reveals load-induced faults such as structural resonance or unbalanced forces

• Prevents unexpected failures and improves reliability

• Supports precision maintenance and long-term asset planning

Key Areas Analyzed

• Compressor movement and motor shaft alignment

• Fan blade balance and bearing wear

• Frame, base, and structural resonance

• Coupling and gearbox performance (if applicable)

• Vibration response to load changes

Our Dynamic Vibration Analysis Process

Sensor Installation and Setup

We mount triaxial accelerometers and velocity sensors on critical components to capture multidirectional vibration under varying load conditions.

Real-Time Data Collection

Sensors collect data during actual chiller operation—capturing fluctuations in frequency, amplitude, and displacement as the load varies.

Advanced Signal Processing

Using tools like Fast Fourier Transform (FFT), time waveform analysis, and order tracking, we isolate vibration signatures that indicate:

• Looseness or rotor imbalance

• Misalignment between motor and compressor shafts

• Dynamic resonance affecting structural components

• Harmonic distortion from fan or motor irregularities

Comprehensive Reporting

We provide a detailed report with:

• Dynamic vibration readings at multiple load points

• Root cause analysis of anomalies

• Severity ratings

• Recommendations for corrective actions (rebalancing, realignment, bearing replacement, etc.)

Benefits of Dynamic Vibration Analysis

• Provides accurate, load-specific fault detection

• Uncovers issues that static testing may miss

• Helps prevent critical mechanical failures

• Improves chiller performance and energy efficiency

• Reduces unplanned downtime and repair costs
