CO₂ as a refrigerant generates high system pressures. Tubes and components must exhibit high resistance to pressure. We offer plain and inner-grooved tubes also in K65, a high-strength copper alloy. K65 not only makes it possible to reduce the wall thicknesses and consequently the amount of material used but also allows our customers to profit from the excellent thermal conductivity of copper. The processing of K65 can usually be carried out with already existing machines and tools. K65 is perfectly weldable and solderable.

We would be very glad to discuss with you which material – copper or K65 - best meets your requirements.
