Tube

Air conditioning and refrigeration inner grooved copper tube (LWC)

Nacobre Denomination: 122

Designation: Phosphorus Deoxidized

High Residual Phosphorus(DHP)

Nacobre inner grooved tube is a seamless and welded copper tube with smooth O.D. surface and helical, integral ridges on the I.D. for enhanced heat transfer. The internal ridges significantly improve the efficiency of heat exchangers in which refrigerant condenses or evaporates within the tube. Typical applications include fin and tube evaporator and condenser coils for air conditioners, freezers, and refrigerators.
