K65 Fittings

The main advantage is the mechanical strength of K65. Because of the high strength of the material, the K65 product can be made with comparatively thinner walls. The light weight of tubes made of K65 means not only a saving in material, but also easier handling, for example when mounting the tubes on ceilings.

In refrigeration, and in particular in the area of supermarket refrigeration systems, more and more ecology-oriented plant concepts are being implemented. The modern, environment-friendly refrigerant CO2 that is used here leads to high operating pressures. For these applications the new K65 tube system is available. Tubes and fittings are made of the high-strength copper alloy K65 which has already been used with success in electrical engineering and the automotive industry. K65 allows economical installation of refrigeration systems with operating pressures up to 120 bar. K65 has good processing properties which are similar to those of copper. K65 tubes may be brazed to K65 fittings in the traditional way. K65 fittings are manufactured by IBP Conex. Safety ensured by two well-known manufacturers, K65 tubes and K65 fittings fall under a joint system guarantee that includes CO2 applications up to 120 bar for the items listed.
