Air-Cooled Chiller Tube Bundle Replacement – EKG M&E Sdn Bhd

At EKG M&E Sdn Bhd, we provide complete tube bundle replacement services for air-cooled chillers, ensuring your system regains peak efficiency, heat transfer performance, and long-term reliability. When a large portion of chiller tubes are corroded, fouled, leaking, or blocked, replacing the entire tube bundle is often more cost-effective and sustainable than replacing individual tubes or the entire unit.

What Is a Tube Bundle Replacement?

A tube bundle refers to the group of heat exchanger tubes within the evaporator or condenser coil. Replacing the entire bundle involves removing the old core and installing a new, factory-built or custom-fabricated assembly, restoring the chiller’s thermal performance to like-new condition.

When to Consider Tube Bundle Replacement

• Extensive corrosion or pitting across multiple tubes

• Chronic refrigerant leakage or tube wall thinning

• Internal blockages, scale, or mineral buildup that can’t be cleaned

• Reduced cooling capacity and energy efficiency

• Structural fatigue or cracking from long-term use

Our Tube Bundle Replacement Process

System Inspection and Diagnosis

We evaluate the chiller's current condition using thermal imaging, pressure testing, and visual inspection to determine the extent of tube damage.

Removal of the Existing Tube Bundle

• Safe disconnection and removal of the existing tube bundle

• Cleaning and preparation of the tube sheet, shell, or coil housing for the new bundle

Custom Fabrication or OEM Supply

• Supply of OEM-compatible or custom-fabricated tube bundles made from copper, stainless steel, or high-performance alloys

• Precision manufacturing to match original design specifications or system upgrades

Installation & Sealing

• Accurate insertion of the new bundle into the chiller unit

• Brazing, welding, or mechanical expansion methods to ensure a tight, leak-free seal

• Connection to refrigerant and water circuits

Pressure Testing & System Recommissioning

• Full leak and pressure testing of the newly installed tube bundle

• Refrigerant recharging, temperature calibration, and performance validation to confirm restored efficiency

Benefits of Tube Bundle Replacement

• Restores heat transfer efficiency and cooling output
