How is copper ACR tubing manufactured for use in refrigeration systems?

Copper ACR (Air Conditioning and Refrigeration) tubing is specifically designed for use in refrigeration systems due to its excellent thermal conductivity and resistance to corrosion. The correct manufacturing process involves deoxidizing the copper to remove any moisture that might compromise the tubing's integrity. After deoxidization, the tubing undergoes dehydration, which ensures that any remaining water vapor is eliminated, thus preventing oxidation during transport and installation.

Purging the tubing is another essential step, as it involves flushing it with nitrogen to remove any contaminants or impurities. This inert gas fills the tubing to further safeguard against oxidation and ensures the internal environment of the tubing remains clean. Finally, the tubing is filled with nitrogen to maintain a protective atmosphere and prevent any degradation during handling and installation.

This specific combination of steps is crucial for assuring the tubing remains in optimal condition for high-pressure applications found in refrigeration systems. This helps enhance the overall efficiency and reliability of the refrigeration system when the ACR tubing is eventually installed.
