With the acquisition of the Rutten Turbines S.A. in 2001 Rösler took a major step in expanding and rounding off its portfolio of high performance blast turbines. The proven Rutten Gamma turbines, equipped with components made from carbide steel, are characterized by their extremely long service life of up to 30,000 operating hours resulting in significantly higher equipment uptimes and drastically reduced time requirements for maintenance. Moreover, they offer substantial savings in energy consumption and spare part costs. The blades were given a concise design with a high recognition value, which, in addition, allows using them twice. Rutten Gamma turbines are installed in a wide range of new shot blast equipment and can be easily retrofitted into existing shot blast machines.
