Air-Cooled Chiller Imbalance and Misalignment Check – EKG M&E Sdn Bhd

At EKG M&E Sdn Bhd, we provide professional imbalance and misalignment checks for air-cooled chillers, ensuring smooth operation, reduced wear, and optimal energy efficiency. Fan assemblies, compressors, and motors in chillers are susceptible to rotational imbalance and shaft misalignment, which can cause excessive vibration, premature component failure, and higher operating costs if left uncorrected.

Why Imbalance and Misalignment Checks Are Important

• Prevents vibration-related damage to motors, fans, and compressors

• Reduces bearing wear, noise, and energy consumption

• Extends equipment lifespan and improves reliability

• Supports predictive maintenance and performance optimization

• Ensures safe and smooth operation of rotating equipment

Common Causes of Imbalance & Misalignment

• Uneven fan blades or accumulated debris

• Shaft displacement from thermal expansion or settling

• Improper motor installation or worn couplings

• Structural shifts due to vibration or loose mounts

• Assembly defects or wear in critical rotating parts

What We Check

• Fan blade and rotor balance

• Compressor and motor shaft alignment

• Belt and coupling tension (if applicable)

• Mounting base level and stability

• Vibration and resonance patterns

Our Imbalance and Misalignment Check Process

Visual & Mechanical Inspection

We begin by visually inspecting components for signs of wear, loose bolts, misaligned mounts, or bent shafts.

Precision Vibration Testing

Using vibration sensors and spectrum analyzers, we measure rotational frequencies and amplitude to detect imbalance or misalignment.

Laser Shaft Alignment (if required)

For high-accuracy results, we perform laser alignment between motors and compressors or fan assemblies to achieve manufacturer-recommended tolerances.

Dynamic Balancing Analysis

Fan assemblies are tested and adjusted for rotational balance, correcting mass distribution or blade deformation issues on-site when needed.

Reporting and Recommendations

You receive a comprehensive report that includes:

• Vibration readings and alignment findings

• Identified imbalance or misalignment issues
