Air-Cooled Chiller Structural Vibration Testing – EKG M&E Sdn Bhd

At EKG M&E Sdn Bhd, we provide specialized structural vibration testing services for air-cooled chillers, ensuring the mechanical integrity and stability of your chiller's support system. Structural vibration—often caused by resonance, mounting issues, or external influences—can compromise system performance, cause premature component failure, and even damage building infrastructure if left unchecked.

Why Structural Vibration Testing Is Essential

• Detects resonance frequencies that amplify vibration

• Prevents frame fatigue, cracking, or structural damage

• Identifies loose, misaligned, or unstable mounts

• Enhances chiller safety, performance, and reliability

• Supports compliance with industry vibration standards

What We Test

• Chiller frame and base for rigidity and resonance

• Mounting supports, bolts, and isolation pads

• Surrounding structures (e.g., platforms or rooftops)

• Interaction between rotating components and frame vibration

• Response to load changes or start/stop cycles

Our Structural Vibration Testing Process

Visual and Mechanical Inspection
We examine the entire chiller structure for signs of looseness, fatigue, or improper mounting.

Sensor-Based Monitoring
We install triaxial vibration sensors and accelerometers on the frame, supports, and key structural contact points.

Frequency and Mode Analysis
Using FFT (Fast Fourier Transform) and modal analysis, we identify:

• Dominant vibration frequencies

• Harmonic resonance

• Vibration transmission paths from rotating equipment to the frame

Root Cause Identification
We correlate structural vibrations with mechanical sources such as fans, motors, or compressors, and determine whether the issue stems from the chiller itself or the mounting structure.

Reporting and Recommendations
We provide a comprehensive report that includes:

• Vibration frequency spectrum and severity levels

• Structural weak points or unstable mounts

• Corrective recommendations (e.g., damping, reinforcement, isolation pad upgrade)

Benefits of Structural Vibration Testing

• Protects chiller integrity and prevents long-term damage

• Reduces vibration-related noise and occupant complaints

• Ensures safe and compliant operation

• Improves system reliability and component life

• Enables data-driven upgrades to mounting or support systems
