All-Aluminum Construction – Tube and fin both made of aluminum, eliminating galvanic corrosion risk at the tube-fin joint that occurs in copper-aluminum coils. No copper-aluminum joint means no brazing points on the main body, significantly reducing leak risk.
Lightweight & Cost-Effective – Aluminum is approximately 70% lighter than copper by volume, reducing unit weight and material cost. Lower weight translates to easier handling, reduced shipping costs, and less structural load on the refrigerator cabinet.
Frost-Free Optimized Design – Designed specifically for no-frost refrigerator systems, with flexible fin pitch engineering to optimize air flow patterns and defrost performance. Fin pitch can be freely engineered per cooling requirement.
Enhanced Heat Transfer – Fin punched with 1.5mm flanging height directly contacts the aluminum tube, greatly increasing heat exchange area. Mechanical tube expansion ensures tight fin-to-tube bonding, increasing heat exchange efficiency by 40–60% compared to loose contact designs.
Super Clean for R134a & R600a – Strict inner cleanliness control: residual moisture ≤25mg/100cm³, residual impurity ≤30mg/100cm³. Suitable for R134a and R600a refrigerant systems.
Corrosion-Resistant Surface Treatment – Chemical oxidation or cathode oxidation with 12–30μm oxidation film, providing ≥96hrs salt-spray resistance. Suitable for humid environments and extended service life.
Stable Bulk Supply – Annual capacity of 3.5 million sets, daily output of 8,000–10,000 pieces, supporting rolling replenishment and reducing inventory capital occupation.
OEM & ODM Support – Custom logo, packaging, and product labeling available. Can produce according to customer drawings or samples, and assist in designing new models.
Batch Traceability – Each batch of goods undergoes strict quality inspection.
Export Packaging – Seaworthy carton and pallet packaging, suitable for long-distance ocean shipping.
