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

At EKG M&E Sdn Bhd, we provide specialized pressure-tested tube replacement services for air-cooled chillers, ensuring that each tube installed meets the highest standards of safety, durability, and performance. Over time, chiller tubes can develop leaks, corrosion, or blockages, affecting cooling efficiency and system reliability. Our approach focuses not just on replacing tubes—but verifying their strength and integrity through comprehensive pressure testing.

Why Pressure-Tested Tube Replacement Matters

• Guarantees leak-free performance under high-pressure operation

• Prevents refrigerant loss and compressor stress

• Ensures system safety and compliance with HVAC standards

• Reduces the risk of future breakdowns caused by weak or faulty tubes

• Extends the lifespan of your chiller system

Our Pressure-Tested Tube Replacement Process

System Inspection & Tube Diagnosis

We begin with a detailed system evaluation using leak detection, thermal imaging, and pressure readings to identify underperforming or leaking tubes.

Tube Removal & Coil Cleaning

Faulty tubes are carefully extracted from the coil block. The surrounding coil area is cleaned to remove debris, corrosion, and contaminants.

Custom Tube Fabrication & Installation

We fabricate and install copper or aluminum tubes that match OEM or upgraded specifications. Each tube is cut, bent, and fitted with precision.

Brazing & Sealing

All joints are sealed using high-strength brazing or welding techniques to ensure durability and withstand refrigerant system pressures.

Individual Tube Pressure Testing

Before recommissioning, every replaced tube is individually pressure-tested using nitrogen or other approved methods to confirm structural integrity and leak-free sealing.

System Recharging & Performance Verification

Once testing is complete, the system is recharged with refrigerant, followed by full system calibration and cooling performance checks.

When to Consider Pressure-Tested Tube Replacement

• Recurring leaks or refrigerant pressure drops

• Physical damage or visible corrosion on tube surfaces

• Poor heat transfer and reduced cooling capacity

• Preparation for long-term, high-performance HVAC operation
