HVAC Heat Exchange Tubes

HVAC heat exchange tubes are core components for air conditioning and heat pump systems. Kenergy produces high-precision copper tubes with inner grooved or smooth surfaces, designed for R32, R410A, and other common refrigerants. With 28 years of expertise, our tubes deliver 30-50% higher heat transfer efficiency, supporting energy-saving and compact system designs for residential, commercial, and industrial HVAC applications.

Inner Grooved Copper Tubes

Internal helical grooves increase surface area for 30-50% higher heat transfer efficiency. Optimized for R32/R410A refrigerants. Available in various groove patterns (herringbone, cross-hatch) and diameters from 5mm to 15.88mm.
