Aluminum Fin Copper Tube Condenser for Trane Air-Cooled Chiller Replacement

When an air-cooled chiller such as the Trane RTAD 125 reaches mid-life or begins showing performance degradation, the condenser coil is often one of the first components to require replacement. Years of outdoor exposure, corrosion, fouling, and refrigerant leaks can significantly reduce heat transfer efficiency. A high-quality Aluminum Fin Copper Tube Condenser designed as a direct replacement provides a cost-effective way to restore the chiller’s cooling capacity and extend its service life without replacing the entire unit.

Key Features

1. Copper Tube + Aluminum Fin Construction

• High-efficiency copper tubes ensure excellent thermal conductivity.

• Hydrophilic or epoxy-coated aluminum fins improve heat transfer and corrosion resistance.

• Advanced mechanical expansion ensures a perfect bond between tubes and fins.

2. Exact Replacement for Trane RTAD 125

• Tube diameter, pattern, and wall thickness match original design

• Header configuration and refrigerant circuiting replicated

• Same mounting points for easy installation

• Compatible with the chiller’s original refrigerant (R407C, R134a, or upgraded refrigerants where applicable)

3. Enhanced Corrosion Protection

Options include:

• Blue epoxy coating

• Golden hydrophilic coating

• Phenolic coating

• Anti-salt spray treatment for coastal environments

These options extend coil life significantly compared to the original factory-installed coils.

4. High-Strength, Durable Construction

• Heavy-gauge copper tubes for long service life

• Optimized aluminum fin spacing for outdoor airflow conditions

• Leak-tested at high pressure before shipment

5. Energy-Efficient Performance

A new condenser coil lowers condensing temperature, resulting in:

• Improved COP

• Reduced compressor power consumption

• Faster cooling response

• Lower operating costs

Benefits of Replacing the Condenser Instead of the Entire Chiller

Many facility operators choose coil replacement because it offers:

✔ Lower Investment Cost

Up to 70% savings compared to buying a new air-cooled chiller.

✔ Minimal Downtime

Replacement coils can be installed quickly, often in less than a day.

✔ No Structural or Control Changes

Keeps all original controls, compressors, fans, and frame.

✔ Restores Factory Cooling Capacity

A new coil restores heat rejection capability to original performance.
