Nexnice high-performance Inner Grooved Copper Tubes are engineered with advanced Micro-fin technology to maximize heat exchange efficiency in HVAC and refrigeration systems.
Advanced Heat Transfer Design
- Micro-fin Technology: Increases internal surface area by 20%-50% compared to smooth tubes.
- Optimized Helix Angle: Precision-engineered spiral grooves (15°–30°) create refrigerant turbulence, preventing “dry-out” and enhancing thermal conductivity.
- Premium Material: Made from C12200 phosphorus-deoxidized copper (99.9% Cu) for superior durability.
