Pancake Copper Coil

-- Steady & Reliable Manufacturer --

The Versatile Standard for HVAC Service and Repair

The Pancake Copper Coil is perhaps the most recognizable form of copper tubing in the global plumbing and HVAC markets. Named for its flat, circular winding that resembles a pancake, this format is designed for portability, ease of handling, and on-site versatility. Unlike rigid pipes, pancake coils are fully annealed (softened), allowing them to be bent by hand or with simple tools without the risk of cracking or kinking. This makes them indispensable for residential air conditioning installations, where installers must navigate tight spaces, wall cavities, and complex routing. At Zhejiang Jingliang, we manufacture our pancake coils with a focus on "Mirror-Finish" internal cleanliness and nitrogen-purged dehydration to ensure they are ready for the most sensitive refrigerant applications.

A key feature of our pancake coils is the consistency of the wall thickness and the grain structure. We use a controlled annealing process in a "Bright Annealing" furnace with a protective atmosphere. This results in a scale-free, oxidation-free surface both inside and out. Our coils are typically dual-certified to meet both ASTM B280 (for air conditioning) and ASTM B88 (for plumbing) standards. This dual-purpose capability allows distributors to stock fewer SKUs while meeting a wider range of customer needs. Whether it's a 15-meter or 50-foot coil, we ensure that every unit is pressure-tested and sealed with high-quality end caps to prevent moisture ingress during storage. The durability and ease of use of our pancake coils have made them a favorite among HVAC contractors in North America, Europe, and Australia.

Field Installation & Repair Applications

Pancake coils are the primary choice for Split-System Air Conditioning installations, serving as the liquid and suction lines connecting indoor evaporators to outdoor condensers. They are widely used in Residential Refrigeration repair and the installation of ice makers and water filtration systems. In the plumbing industry, soft copper coils are used for Underground Water Service lines because their flexibility allows them to withstand minor soil movement and settling without breaking. They are also common in Fuel Gas (Natural Gas and Propane) piping for both indoor and outdoor applications. Additionally, pancake coils are used in Radiant Floor Heating systems and specialized solar thermal loops where a continuous, joint-free run of pipe is required to minimize potential leak points.

Portability, Flexibility, and Reliability

The "Hand-Bendability" of pancake coils is their greatest advantage, significantly reducing the number of elbows and fittings required in a typical installation, which in turn lowers the total cost of materials and labor. Their "Compact Packaging" makes them easy for technicians to transport in service vans and carry up ladders or into crawlspaces. Our coils offer "Superior Corrosion Resistance" due to the high purity of the C12200 alloy, ensuring a service life of several decades. The "Factory Dehydration" and capping guarantee that the internal circuit remains free of moisture, protecting the system's expansion valves and compressor. For wholesalers, the "Durable Shrink-Wrap" packaging ensures that the product remains clean and marketable even after months on a retail shelf. Ultimately, the Jingliang pancake coil offers a "Plug-and-Play" solution that combines traditional copper reliability with modern cleanliness standards.

Packaging for Retail and Wholesale

Each pancake coil is individually shrink-wrapped with a transparent film and includes a descriptive label. For bulk orders, they are packed into sturdy corrugated cartons and then palletized. We accept T/T, L/C, and D/P. Shipping is typically FOB Ningbo or CIF to your destination port. We have extensive experience in meeting the specific labeling and barcoding requirements of major hardware retail chains. To prevent damage during sea transit, we use moisture-absorbent silica gel packs in every container to ensure the copper arrives with its characteristic bright, "new-minted" shine.

  • Q: Are these coils suitable for R410A and R32 refrigerants?
  • A: Absolutely. Our coils are designed with the wall thickness and burst strength required to safely handle high-pressure modern refrigerants.
  • Q: Can I get custom lengths?
  • A: Yes, we can produce coils in non-standard lengths (e.g., 22 meters) for specific architectural or industrial projects.
