**Advantages of Our Frost-Free Copper Tube Hydrophilic Aluminum Fin Coil Heat Exchanger for Freezing Refrigeration:**
1. The fins are manufactured to a very high standard, featuring plain or wave-type flare positions.
2. The fin edges can be either straight or ripple-shaped depending on the application.
3. All coils undergo 100% leakage testing and are cleaned inside and out using air circulation in a heating oven, followed by nitrogen charging.
4. Mechanical bullet expansion ensures a tight fit between the copper tube and the fin, enhancing heat transfer efficiency in both condensers and evaporators.
5. We source only the highest quality raw materials globally, ensuring that our heat exchangers meet international standards.
6. Available in various copper pipe diameters such as 7mm, 7.94mm, 9.52mm, 12.7mm, 15.88mm, and 16mm.
7. Aluminum foil is available in blue color with hydrophilic and bio-friendly (health) properties.
