The RS150 is the largest UNTHA heavy duty four-shaft shredder and has been developed for especially difficult applications where a high throughput performance, high availability and low maintenance cost are all required.

The highlight of this unique innovation is the newly designed UNTHA Eco Drive. The dynamic and energy-efficient drive concept ensures that the cutting inserts are stopped immediately if foreign objects are pushed in so as to prevent the cutting tools from being damaged. Moreover, this drive permits frequent reversal which is particularly necessary when shredding difficult materials.

The throughput performance can always be optimally configured for the material to be shredded with the variable speed setting option for the cutting shafts. In contrast to high-speed systems (asynchronous motors), these machines do not require wearing parts such as couplings, belts or shear pins, which reduces the machine's vulnerability.

The large RS series can also be equipped with additional separating and conveyor technology, customized hoppers and substructures and control expansions. We offer comprehensive solutions from one source!
