Proven processing technology: brazing instead of welding!.Cost reduction through weight reduction.Pressure resistance tailormade to your needs.K65 in Refrigeration and medical gas tubes.Moreover, K65 tubes are also available in individual dimensions and different delivery forms.įor industrial processing, in particular CO 2 heat exchanger (evaporator / gas cooler) manufacturing, level wound coils (LWC) are offered. 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”. At the same time, K65 tubes have outstanding processing properties, similar to those of standard copper (Cu-DHP/C12200).Īll Wieland K65 tubes are available in the soft condition (R300/O61) to ensure excellent bending / flaring and collaring properties. Wieland K65 alloy provides the mechanical strength high enough to withstand the high operating pressures of CO 2. Wieland K65 tubes have been designed for CO 2 applications in the commercial field, especially that of supermarket refrigeration systems. Wieland supports this turnaround with a tube system that meets the high requirements of CO 2 as a refrigerant. Increased environmental awareness in society and industry has therefore led to a kind of renaissance of natural refrigerants, especially CO 2. 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.
