High quality copper tubes are manufactured from C12200 DHP (Deoxidized High Phosphorus) copper, the standard grade for air conditioning, refrigeration, and plumbing applications. Copper tubes offer excellent thermal conductivity, corrosion resistance, formability, and antimicrobial properties. Available in pancake coils (15-50m for ACR), LWC (Level Wound Coil for automated processing), and straight lengths.
Widely used in HVAC/R systems, plumbing water/gas lines, medical gas systems, and industrial heat exchangers. Available with plain ends, nitrogen-charged and capped for ACR applications to prevent internal oxidation.
