K65 tubes for refrigeration

Natural and safe cooling with the K65 system

In refrigeration, particularly in the field of supermarket refrigeration systems, ecology-oriented plant concepts are increasingly being used. The K65 system is optimized for the special requirements of natural refrigerants.

Environmentally friendly refrigerants such as CO2 R744 require piping systems that are approved for operating pressures of up to 130 bar. The Wieland-K65 tubes and the range of K65 brazing fittings from IBP Conex | Bänninger is a system for high-pressure applications based on copper. It is characterised by the usual ease of processing and the excellent heat transfer properties of copper.

For high pressures the K65 system is a unique combination of tubes and fittings. With K65, Wieland and IBP Conex | Bänninger offer an easy-to-use and safe complete system.
