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

At EKG M&E Sdn Bhd, we provide specialized high-frequency vibration analysis services for air-cooled chillers, helping detect early-stage mechanical faults that standard inspections often miss. High-frequency vibrations are typically caused by bearing wear, cavitation, gear mesh issues, or electrical noise, and they can lead to accelerated component failure if not addressed promptly. Our advanced diagnostic tools allow us to identify these subtle vibrations before they escalate into serious problems.

Why High-Frequency Vibration Analysis Is Critical

• Detects early bearing degradation and microscopic flaws

• Identifies issues like shaft rub, electrical arcing, or gear misalignment

• Prevents unexpected equipment failure and downtime

• Supports precision maintenance and lifecycle planning

• Enhances system reliability, safety, and energy efficiency

Sources of High-Frequency Vibrations in Air-Cooled Chillers

• Compressor bearing wear or lubrication breakdown

• Fan motor electrical noise or unbalanced rotor

• Loose or damaged impellers

• VFD-related electrical interference

• Internal component impact or shaft misalignment

Our High-Frequency Vibration Analysis Process

Sensor Installation and Data Acquisition

We install ultra-sensitive piezoelectric accelerometers capable of capturing vibrations in the high-frequency range (above 1,000 Hz) on compressors, fan motors, and structural components.

Envelope Analysis and Signal Processing

Using envelope detection, FFT (Fast Fourier Transform), and time waveform analysis, we isolate high-frequency components that indicate:

• Bearing flaws (inner/outer race damage, ball wear)

• Impacts or frictional contact (shaft misalignment, loose parts)

• Cavitation or turbulence within refrigerant circuits

Root Cause Identification

We pinpoint the exact source and nature of the high-frequency vibrations and assess the severity using baseline comparison with manufacturer specifications.

Detailed Reporting and Maintenance Recommendations

Our report includes:

• High-frequency data plots and spectrum analysis

• Identified faults with fault frequency correlation

• Recommendations for bearing replacement, lubrication, realignment, or component balancing
