Conex Bänninger, in partnership with Wieland K65 tubes, has developed its K65 fittings for the commercial sector, a solution for high-pressure ACR applications. 

Conex Bänninger CO2 solutions can deliver pressure ratings up to 120 bar (1740 psi). The K65 system also enables businesses to retain their green credentials by utilising the highly pressured CO2 R744 refrigerant. 
Suited to a range of highly pressured refrigeration and air conditioning applications such as installations in office blocks, high rise apartments, schools and supermarkets, the K65 system simplifies specification as there is no tube gauge variation in either Wieland’s alloys and Conex Bänninger’s complementary fittings range.

With installer safety of paramount importance, both the tube and fitting components of the K65 system are UL 207 certified. The K65 range’s excellent processing properties, similar to those of copper, mean that the fittings can be easily brazed to the tubing without the need of expensive or special equipment. 

The thermal conductivity of K65 enables heat to be transmitted through the pipe with improved energy efficiency, higher by a factor of 20 compared to its stainless steel counterparts.  Its high mechanical strength means that it can be manufactured economically and at a lighter weight compared to some alternative materials. 

Bill Barlow, Conex Bänninger UK Sales Director for OEM and ACR,  said: “At Conex Bänninger, we recognise the significant rise in demand for highly pressurised CO2 solutions within commercial refrigeration and air conditioning. To this end, the K65 system offers a best-in-class system. The product not only delivers outstanding pressure withstanding performance of up to 120 bar (1740 psi), but is also an environmentally friendly solution.”

All Conex Bänninger K65 fittings are easily identified by the manufacturers mark, as well as the K65 mark and 120 bar (1740 psi) pressure rating. In addition, the material is slightly magnetic and can be easily distinguished from copper by means of a neodymium magnet – a helpful and practical advantage for installers and system builders.
