Here is the improved and rewritten English version of your content, with added details to meet the 500-character minimum requirement and make it sound more natural and authentic: --- Zeniya Refrigeration and Air Condition Equipment Co., Ltd. is a professional manufacturer established in 2007, specializing in copper tube aluminum fin condenser coils for marine air conditioners and commercial air conditioning systems. Our products are designed for high performance, durability, and efficiency, meeting global quality standards. **Advantages of Our Condenser Coils:** 1. High-quality fins with plain or wave-type flaring. 2. Fin edges can be straight or rippled based on application needs. 3. All coils undergo 100% leakage testing, cleaning in a heating oven, and nitrogen charging. 4. Mechanical bullet expansion ensures optimal heat transfer between the copper tubes and fins. 5. We use only the best raw materials sourced globally to ensure top-tier heat exchangers. 6. Available copper pipe diameters include 7mm, 7.94mm, 9.52mm, 12.7mm, 15.88mm, and 16mm. 7. Blue-colored aluminum foil with hydrophilic and bio-friendly properties. **Key Features:** 1. Materials: Copper, aluminum, galvanized plate. 2. Aluminum foil options: Hydrophilic or bare. 3. Fin types: Louvered, flat, or corrugated. 4. Copper tubes: Grooved or smooth, with various diameters. 5. Adjustable fin pitch: 1.3–8.0 mm. 6. Suitable for refrigerants such as R134A, R22, R404A, and R407C. 7. Voltage options: 220V/1/50Hz or 380V/3/50Hz, and other custom options. 8. Available condensing fans: Shaded pole or outer rotor type. 9. Gas tightness tested under 3.0 MPa pressure. 10. Widely used in refrigeration, cold storage, and cooling systems. 11. Custom manufacturing available per samples or drawings. 12. Production process includes tube bending, fin punching, expansion, drying, welding, leak testing, inspection, and packaging.
