K65 - Sustainable and efficient
Sustainable and efficient – two keywords that have had a decisive impact on our time and have gained in relevance in recent years, especially in refrigeration. Increased environmental awareness in society and industry has therefore led to a kind of renaissance of natural refrigerants, especially CO2. Wieland supports this turnaround with a tube system that meets the high requirements of CO2 as a refrigerant.
Wieland K65 tubes have been designed for CO2 applications in the commercial field, especially that of supermarket refrigeration systems. Wieland K65 alloy provides the mechanical strength high enough to withstand the high operating pressures of CO2. At the same time, K65 tubes have outstanding processing properties, similar to those of standard copper (Cu-DHP/C12200).
All Wieland K65 tubes are available in the soft condition (R300/O61) to ensure excellent bending / flaring and collaring properties.
Wieland K65 tubes are offered from stock in two pressure ranges, 80 bar and 120 bar, and in dimensions ranging from 3/8” up to 2-1/8”.
Moreover, K65 tubes are also available in individual dimensions and different delivery forms.
For industrial processing, in particular CO2 heat exchanger (evaporator / gas cooler) manufacturing, level wound coils (LWC) are offered.

Materials
For a more sustainable future in construction.
With its 100 % share of recycled material, the cuprolife copper tube makes a sustainable difference, and thus makes a significant contribution to the advancement of building and construction as well as building services.
Every cuprolife tube from Wieland is manufactured in keeping with the mass balance approach – using a process with 100 % recycled copper. As the starting point when verifying cuprolife, TÜV SÜD tested the procedure for calculating the 100 % recycled content*.
The new standard in copper tubes: cuprolife®.
Thanks to cutting-edge manufacturing techniques, cuprolife tubes exceed even the highest requirements. Optimal efficiency and reliability are guaranteed along with an exceptional service life. cuprolife tubes are universally usable. cuprolife is permanently in stock and can be supplied in any size from 6 x 1 mm to 159 x 3 mm.
