Heat Pump Copper Tube

-- Steady & Reliable Manufacturer --

The Engine of Modern Eco-Friendly Heating and Cooling Systems

Heat Pump Copper Tubes form the vital circulation pathway for modern residential, commercial, and industrial heat pump systems. Designed to operate across dual heating and cooling cycles, these high-performance copper tubes play a crucial role in enabling heat energy extraction from ambient air, ground soil, or water sources. Made from high-purity C12200 phosphorus-deoxidized copper (Cu-DHP), our heat pump copper tubing offers exceptional thermal conductivity, structural integrity, and resistance to cyclic fatigue. As global demand shifts toward energy-efficient HVAC solutions, heat pump technology requires copper tubing that can reliably endure frequent thermal stress, pressure spikes, and harsh environmental conditions without performance degradation.

At Zhejiang Jingliang, our heat pump copper tubes are manufactured using precision cold drawing and atmospheric bright annealing processes to guarantee uniform grain structure, optimal wall consistency, and superior mechanical flexibility. Our internal cleanliness standards ensure that the inner bore remains virtually free from oxide scales, carbon residue, and moisture. This ultra-clean interior protects heat pump expansion valves and compressors from premature wear and chemical contamination. Whether installed in air-to-air split heat pumps, ground-source geothermal networks, or commercial air-to-water heat pump boilers, Jingliang heat pump copper tubes deliver long-term reliability and peak thermodynamic efficiency.

Residential, Geothermal, and Commercial Heat Pumps

Heat pump copper tubes are extensively utilized in "Air-to-Air Heat Pumps" and "Ductless Inverter Systems" for residential heating and cooling. They form the core loop in "Ground-Source Geothermal Heat Pumps," buried deep underground to absorb stable earth temperatures. "Air-to-Water Heat Pump Water Heaters" rely on these tubes for transferring thermal energy directly to domestic water storage tanks. In commercial developments, they are deployed in "VRF/VRV Heat Recovery Systems" to allow simultaneous heating and cooling across different building zones. They are also widely integrated into "Commercial Swimming Pool Heat Pumps" and "Industrial Process Water Chiller-Heaters."

Exceptional Energy Efficiency and High Thermal Fatigue Resistance

The main advantage of our heat pump copper tube is its "Superior Thermal Conductivity," which maximizes coefficient of performance (COP) ratings across hot and cold operating cycles. Its "High Burst Strength" guarantees safe continuous operation under high-pressure eco-friendly refrigerants. Thanks to "Precision Mechanical Bending Capacity," installers can easily route the tubing through complex walls without kinking. The "Corrosion-Resistant Copper Alloy" ensures protection against atmospheric moisture and thermal oxidization. Furthermore, our tubes feature "Mirror-Clean Internal Bore," drastically reducing compressor failure rates and preserving heat exchanger efficiency over decades.

Sealed Export Packaging and Global Shipping

Heat pump copper tubes are packed with factory-installed rubber end caps to keep out dirt and atmospheric humidity. Coils are shrink-wrapped in plastic film and loaded into heavy-duty cartons, while straight lengths are packed in wooden cases. Payment terms are 30% T/T deposit and 70% L/C at sight. Shipments are handled via Ningbo or Shanghai ports with complete "Mill Test Certificates" and "Eddy-Current Inspection Reports." Custom dimensions and pre-insulated options are available upon request.

  • Q: Are heat pump copper tubes compatible with natural refrigerants like R290 (Propane)?
  • A: Yes, our heat pump copper tubes are fully rated for R290, R32, and R410A refrigerants due to their heavy wall design and high burst pressure thresholds.
  • Q: Do these tubes support flaring and expansion without cracking?
  • A: Absolutely. Our uniform bright annealing process provides high ductility, making flares and socket expansions fast and reliable.
