The copper pancake coil from Qingdao Zerui Metal Co., Ltd. is engineered for HVACR applications, using electrolytic copper with a purity of Cu 99.99% as defined by ASTM B743 and EN 12735-1 standards. The coil is wound into a compact pancake configuration to optimise surface area for efficient heat transfer, a critical requirement in residential and commercial air conditioning systems. It is available in single-layer and double-layer types, offering flexibility for different system designs.
Electrolytic copper of this grade provides high thermal conductivity and corrosion resistance, ensuring durability in demanding environments. The material’s lightweight yet robust nature simplifies installation and reduces maintenance needs. Standard industry versions of these coils often use oxygen-free copper (OFHC) for even higher purity, though the listed grade here meets typical HVACR performance demands. The pancake winding maximises contact with refrigerant or air, improving energy efficiency in cooling cycles.
These coils are primarily sourced by contractors, OEM manufacturers, and HVAC parts distributors for use in air conditioning units, refrigeration systems, and heat pumps. The compact design allows integration into tight spaces, while the copper’s malleability supports custom bending or shaping during assembly. Buyers should confirm compatibility with their system’s refrigerant type and pressure ratings, as well as packaging and lead-time details with Qingdao Zerui Metal Co., Ltd. directly.

Before placing an order, verify the coil’s compatibility with your system’s refrigerant type and pressure ratings, as mismatches can lead to inefficiency or failure. Request the supplier’s mill test certificates (MTCs) to confirm the Cu 99.99% purity and compliance with ASTM B743 or EN 12735-1. Additionally, check whether the coils are supplied in single-layer or double-layer configurations to match your design requirements.
Confirm logistics details such as lead times, which may vary based on Qingdao Zerui Metal Co., Ltd.’s production schedule and your order volume. Clarify Incoterms (e.g., FOB Qingdao) and payment terms upfront, as these will impact your total landed cost. For bulk shipments, discuss packaging options to ensure protection against moisture and physical damage during transit, especially for long sea voyages.
Conduct quality checks upon receipt, including visual inspections for surface defects or excessive tarnish and dimensional verification to ensure the coils meet the stated tolerances. For critical applications, consider third-party inspection or testing for thermal conductivity and corrosion resistance. Ensure all documentation, including MTCs and packing lists, is complete and accurate to facilitate customs clearance and traceability in your supply chain.
