2 combirex CX50 Combirex CX50 pneumatic brake has been the reference brake in the converting industry and it is still widely used on unwinders and in various applications. The CX50 has been designed by Giampiero Re, in the 1980s, who later founded the company, Renova, in 005. In the 1980 s Mr. Re applied an innovative axial fan ventilation on the CX mono-disc brakes which helped to decrease the temperature faster than before. This led to a reduction of pad wear and an increased web tension quality compared to previous brakes without a cooling fan. Today, the Renova CX pneumatic brake is the result of continuous research and improvements. Great importance is given to the selection of precise materials to reach and always provide a higher performance and less wear of components. Made in Italy { All Renova s products are managed by TUV ISO
