Product Description:
Copper Coil / Pancake Coil – The Standard Choice for HVAC & Refrigeration Lines
Copper coils (also known as pancake coils or copper tubing coils) are seamless copper tubes wound into circular coils. They are manufactured from high-purity copper through a precision drawing and annealing process, resulting in a soft, flexible tube that can be easily bent and routed without kinking.
Why choose copper coil over straight pipe:
Long continuous lengths – Reduce joints and potential leak points
Flexible installation – Easy to bend around obstacles
Cost-effective – Less scrap, faster installation
Space saving – Compact coil packaging for transport and storage
Key standards: ASTM B280 (USA), EN 12735-1 (Europe), AS/NZS 1571 (Australia/New Zealand), JIS H3300 (Japan)
Typical applications: Air conditioning refrigerant lines, refrigeration systems, heat pumps, water heaters, solar heating systems, oil coolers, plumbing, and gas distribution.
Each coil is cleaned, dried, capped, and vacuum-sealed or nitrogen-purged to ensure internal cleanliness. MOQ: 500 kg – 1 ton, trial orders welcome.
