**Advantages of Our Frost-Free Copper Tube Hydrophilic Aluminum Fin Coil Heat Exchanger for Freezing Refrigeration:**
1. High-quality fins with plain or wave-type flaring, ensuring excellent heat transfer performance.
2. Fin edges can be straight or ripple-shaped depending on the application requirements.
3. All coils are 100% tested for leaks and cleaned using air circulation in a heating oven, then charged with nitrogen to ensure integrity.
4. Mechanical bullet expansion of copper tubes to fins ensures efficient heat transfer in both condensers and evaporators.
5. We use only the highest quality raw materials sourced globally to meet international standards.
6. Available in plain copper tubes with diameters ranging from 7mm to 16mm.
7. Blue-colored hydrophilic aluminum foil with bio-friendly properties improves moisture management and hygiene.
