Condenser Copper Tubing

-- Steady & Reliable Manufacturer --

Optimizing Heat Rejection in Modern Cooling Systems

Condenser copper tubing is the engineering heart of heat rejection systems, designed to facilitate the rapid transfer of thermal energy from a high-pressure refrigerant gas to the surrounding air or water. In the condensation process, the efficiency of the copper wall is the deciding factor in the overall energy rating of the HVACR system. At Zhejiang Jingliang, our condenser tubing is manufactured to provide the highest possible thermal conductivity while maintaining the mechanical strength to handle high-temperature, high-pressure discharge gases. We use high-purity C12200 copper, which offers a thermal conductivity of approximately 390 W/(m·K). To further enhance performance, we offer both smooth-bore and internally-grooved (micro-fin) designs that increase the internal surface area and promote turbulence, significantly boosting the heat transfer coefficient compared to standard tubing.

The environment within a condenser is uniquely challenging; the tubing is exposed to the highest temperatures in the refrigeration cycle and often to corrosive outdoor elements. Our condenser copper is "Hard-Drawn" or "Half-Hard" to provide the structural rigidity needed for large-scale coil assemblies, preventing sagging and vibration-related fatigue. We also focus on "Surface Integrity"—our tubes are free from scratches and imperfections that could lead to external corrosion or impede the bonding of aluminum fins. For water-cooled condensers used in marine or industrial settings, we offer specialized copper-nickel alloys (CuNi) that provide superior resistance to salt-water corrosion and biofouling. Whether you are building a small residential condenser or a massive industrial cooling tower, our tubing provides the thermal efficiency and long-term durability needed for peak performance.

Applications in Thermal Management

Condenser copper tubing is found in the Outdoor Units of residential split-system air conditioners and the Heat Rejection Coils of commercial chillers. It is also the primary component in Industrial Refrigeration condensers used in food processing and cold storage. In the automotive sector, it is used for the manufacturing of AC condensers and oil coolers. Power Plants use large-diameter condenser tubes for steam-to-water heat exchange. In the renewable energy sector, they are used in the condensers of organic Rankine cycle (ORC) systems and solar thermal units. Water-cooled condensers in Marine HVAC systems also rely on our specialized corrosion-resistant copper-nickel tubing. Any system that requires the phase change of a fluid from gas to liquid through heat rejection will utilize our precision condenser tubing to maximize its efficiency.

Advantages of High-Efficiency Condenser Copper

The primary advantage is "Maximum Heat Transfer Rate"—our high-purity copper and inner-groove technology allow for smaller, more compact condenser designs that achieve higher SEER and EER ratings. "Mechanical Strength" is another key benefit; our hard-drawn tubes can handle the high-pressure discharge from modern compressors without deformation. Our tubing also offers "Superior Fin-to-Tube Bonding"—the precise outer diameter and surface quality ensure that aluminum fins can be tightly expanded onto the tube, creating an efficient thermal path. For the manufacturer, our "Consistency of Temper" means that the tubes can be bent into "hairpin" shapes on automated machinery with zero defects. Finally, the "Corrosion Resilience" of our material ensures that the condenser maintains its efficiency over many years, even when exposed to pollution, salt air, and debris in outdoor environments.

OEM Logistics and Packaging

We supply condenser tubing in LWC (Level Wound Coils) for high-speed coil production or in precision-cut straight lengths for large industrial chillers. Payment is typically T/T or L/C at sight. To prevent damage during transit, we pack our LWC on reinforced pallets with extra shrink-wrapping and edge protection. Straight lengths are shipped in rigid wooden crates. Every batch is 100% eddy-current tested at the factory to ensure there are no leaks before it reaches your assembly line. We offer "Project-Scale" logistics, coordinating with OEM production schedules to deliver the exact amount of tubing needed for each month's manufacturing run. Our documentation includes full material traceability and thermal performance certificates to assist with your system's energy certification.

  • Q: What is the benefit of inner-grooved tubing in a condenser?
  • A: Inner-grooved tubing increases the internal surface area by 30-50% and creates turbulence in the refrigerant flow, which can increase the heat transfer efficiency by up to 10-15% compared to smooth tubes.
  • Q: Can I use copper-nickel for a condenser?
  • A: Yes, for water-cooled condensers using seawater or brackish water, copper-nickel (90/10 or 70/30) is the superior choice due to its high resistance to erosion and corrosion.
