The high operating pressures of CO₂ refrigeration systems place demanding mechanical requirements on heat exchanger tubes. Wieland K65 provides significantly higher strength than standard Cu-DHP copper while retaining practical forming and processing properties.
The higher material strength allows reduced wall thicknesses, helping lower material input and tube weight. K65 tubes can be joined by brazing and supplied in delivery forms suitable for industrial heat exchanger production.
Smooth K65 industrial tubes are designed for manufacturing refrigeration components and heat exchangers requiring increased pressure resistance.
The high-strength K65 alloy enables weight-optimized tube designs while maintaining good processing characteristics. Dimensions, wall thicknesses and delivery forms can be adapted to the requirements of the heat exchanger and manufacturing process.
Innergrooved K65 tubes combine the mechanical strength of the K65 alloy with an internal fin structure designed to improve heat transfer.
They are used in CO₂ heat exchangers such as evaporators and gas coolers and are available in individual dimensions as level-wound coils or straight lengths.
