Pancake Copper Coils
Seamless copper tubes supplied in pancake coil form, specially manufactured for HVAC/R, plumbing, medical gas, and refrigeration applications, ensuring excellent formability, high thermal conductivity, and ease of installation.
Pancake copper coils are specially manufactured from C12200 (DHP) phosphorus deoxidized copper and annealed to provide maximum flexibility and ease of installation on-site. The soft temper allows for seamless bending around obstacles without the need for additional fittings, significantly reducing the risk of leaks in refrigeration circuits.
