Copper Tubes for Refrigeration, Air Conditioning and HVAC Systems

Copper tubes are the global standard in the refrigeration, air conditioning and HVAC industry. Their unique combination of strength, thermal efficiency and durability makes them the most reliable option for the safe and stable conduction of refrigerants, oils and fluids across residential, commercial and industrial systems.

Key Properties of Copper in Refrigeration

 1. High thermal conductivity – ensures efficient heat transfer in evaporators, condensers and heat exchangers.

 2. Ductility and flexibility – allows easy bending without cracks, minimizing joints and leak points.

 3. Corrosion resistance – withstands humid, saline or industrial environments.

 4. Mechanical strength – suitable for high-pressure and temperature variations.

 5. Chemical compatibility – works with all modern refrigerants (HFC, HCFC, HFO, CO₂, hydrocarbons).

Types of Copper Tubes for HVAC/R

Copper Coil Tubes (Rolls)

 • Flexible and easy to install in split and inverter systems.

 • Common lengths: 15 m, 30 m, 50 m.

 • Available sizes: 1/4”, 3/8”, 1/2”, 5/8”, 3/4”.

Straight Copper Tubes

 • Available in 5 m and 6 m lengths.

 • Widely used in VRV/VRF systems, central HVAC and industrial refrigeration.

 • Provides greater control in large-scale installations.

Insulated Copper Tubes

 • Coated with elastomeric foam or polyethylene.

 • Prevents condensation and reduces energy loss.

 • Ideal for visible or outdoor installations.

Copper Capillary Tubes (Microtubes)

 • Tiny diameter (0.5 mm – 5 mm).

 • Used as expansion devices in refrigerators and air conditioners.

 • Provides precise and stable refrigerant flow.

PVC-Coated Copper Tubes

 • Extra protection against UV rays, impacts and chemical agents.

 • Recommended for outdoor installations.

Inner Grooved Copper Tubes

 • Designed with internal microchannels that increase heat transfer surface.

 • Improves energy efficiency in modern HVAC equipment.

Main Applications

 • Residential and commercial air conditioning (split, multi-split, inverter).

 • Central HVAC systems in offices and buildings.

 • VRV and VRF systems in hotels, hospitals and shopping centers.

 • Commercial refrigeration in supermarkets, cold rooms and display cabinets.

 • Industrial refrigeration for food, pharmaceutical and chemical plants.

 • Heat pumps and geothermal systems.

International Standards and Certifications

Our copper tubes comply with the highest international quality standards:

 • ASTM B280 – seamless copper tubes for refrigeration and air conditioning.

 • EN 12735-1/2 – European standard for copper tubes in HVAC/R systems.

 • ISO 9001 – certified quality management system.

 • RoHS & REACH – compliant with environmental and safety regulations.

Technical Specifications

 • Outer diameters: 2 mm – 159 mm.

 • Wall thickness: 0.3 mm – 3.0 mm (depending on pressure and refrigerant).

 • Forms: coils, straight lengths, insulated, PVC-coated, capillary tubes.

 • Working pressure: suitable for both high and low-pressure systems.

 • Finishes: bright, annealed, deoxidized, phosphorus-deoxidized copper.

Advantages over Other Materials (Aluminum, Steel)

 • Better thermal conductivity → more efficient heat transfer.

 • Lower risk of leakage thanks to secure brazing and welding.

 • Longer lifespan even under extreme conditions.

 • Universal compatibility with all refrigerants.

 • Faster, easier and more reliable installation.
