The Technology to Create Perfection:
1. Our fins are manufactured to very high quality standards, featuring plain or wave-type flaring positions.
2. The edges of the fins can be straight or ripple, depending on the application requirements.
3. All coils undergo 100% leakage testing and are cleaned using a heating oven with hot air circulation for both internal and external cleaning, followed by nitrogen charging.
4. The mechanical bullet expansion of copper tubes ensures efficient heat transfer in condensers and evaporators.
5. We source only the best raw materials from around the world to produce heat exchangers that meet global quality standards.
6. Plain copper pipes with diameters of 7mm, 7.94mm, 9.52mm, and 12.75mm are available.
7. Aluminum foil in blue color with hydrophilic and health-friendly properties is used.
Features:
1. Materials: Copper, aluminum, and galvanized steel.
2. Aluminum foil: Hydrophilic or bare finish.
3. Fin types: Louver fin, flat fin, or corrugated fin.
4. Copper pipe: Available in various diameters (7mm, 8mm, 9.52mm, 12.75mm, 15.88mm), either grooved or smooth.
5. Fin pitch can be adjusted between 1.8mm and 5.8mm.
6. Hole spacing and row spacing options: 25x21.65mm and 12.7x19.05mm.
7. Suitable for refrigerants such as R134A, R22, R404A, and R407C.
8. Voltage options: 220V/1/50Hz or 380V/3/50Hz, or other custom specifications.
9. Condensing fans: Shaded pole or outer rotor fan motor available.
10. Gas testing under 3.0MPa air pressure to ensure tightness.
11. Widely used in refrigeration systems, cold rooms, and other cooling applications.
12. Custom designs based on samples or drawings are available.
13. Production process includes tube bending, fin punching, expanding, drying, welding, leakage testing, inspection, and packing.
