The NEXNICE ACR Copper Coils (Pancake Coils) are manufactured using high-purity C12200 (TP2) phosphorus-deoxidized copper, ensuring a minimum copper content of 99.9%. Engineered for critical HVAC and refrigeration applications, these soft copper coils comply with international standards including ASTM B280, ISO 9001, and EN 12735. Every hvac copper coil is bright annealed and nitrogen-purged to guarantee a bone-dry, oxidation-free internal surface.
Why Choose NEXNICE Pancake Copper Coils?
✓
Ultra-High Purity & Cleanliness: Made from 99.9% pure C12200 copper. The internal surface exceeds CDA (Copper Development Association) requirements, essential for the optimal flow of R410A and R32 refrigerants.
✓
Premium Ductility: Our soft copper coil undergoes precise bright annealing, allowing for easy bending and flaring without the risk of kinking or cracking, significantly speeding up on-site installation.
✓
Industrial-Grade Protection: Each pancake coil copper unit is capped and moisture-sealed via shrink-wrap (available in single or double-layer), preventing any contaminants from entering during shipping.

Frequently Asked Questions
Q: Why is ASTM B280 the standard for HVAC?
Unlike general-purpose copper tubes, ASTM B280 tubes are specifically designed for the high pressures and extreme cleanliness required in refrigeration (ACR) fields. They are tested to ensure they can handle high-pressure refrigerants without leaking.
Q: Can these coils be used with the new R32 refrigerant?
Yes. NEXNICE hvac copper coils are fully compatible with R410A and R32. Their high wall-thickness consistency and pure copper composition ensure safety under higher operating pressures.
Q: What is a “Pancake Coil”?
A “Pancake Coil” refers to a soft copper coil wound into a flat, circular shape (like a pancake). This packaging makes it extremely convenient to roll out and cut to specific lengths on-site without it tangling.
