Why is this metals shredder so innovatory?

UNTHA’s RS150 contains the new ‘UNTHA Torque Drive’ system, a pioneering engineering concept that has been extensively researched, developed and tested in UNTHA’s state-of-the-art factory for years. This dynamic energy-saving technology allows operators to adjust the metal shredder’s cutting speed and torque, whilst allowing the cutters to frequently reverse without causing machine damage.

Optimised power consumption and cutter protection means the RS150 is perfectly equipped to handle even the toughest metal shredding conditions. The advantage of this sophisticated drive system which has taken years to perfect, is that it now works much more efficiently than other industry equivalent machines. Because it operates without couplings, fly wheels or shear pins, the waste shredder’s reliability is increased and the risk of mechanical failure significantly reduced.

Non–ferrous scrap metal and other metal waste such as WEEE and cables are fed into the main cutters, to be pre-shredded and re-shredded in a single pass. Materials that do not pass through the screen are transferred to the secondary cutters which transport the waste back into the cutting chamber for re-shredding. The final particle size is defined by the chosen screen diameter.

The high torque, slow speed eco-drive concept within this machine will also keep power consumption low, which minimises our carbon footprint and saves on energy costs. You wouldn’t expect these efficiencies within such a heavy duty machine of this size.
