K65® system for high-pressure applications

The K65 tube system ensures natural and safe cooling

K65 copper tubes K65 copper tubes

Refrigeration is making increasing use of plant designed with the environment in mind. This applies, particularly in the field of supermarket refrigeration systems, environmentally friendly refrigerants such as R744 (CO2 grade) require piping systems approved for operating pressures up to 120 bar.

The Wieland-K65 tubes and the range of K65 brazing fittings from IBP together make up a copper-based system for high-pressure applications The usual ease of processing and the excellent heat transfer properties of copper are key features of this system.

Further information can be found on the K65 system website.
