For more than four decades, UNTHA has been developing and producing customized and reliable shredding systems whose applications range from recovering recyclable materials to processing waste into refuse-derived fuels. The company, based in Kuchl, Austria, is now one of the leading manufacturers in this growing and innovative industry. It is showcasing its new QR class in Hannover as a solution that eliminates unplanned downtime and does what it’s designed to do - delivering reliable shredding.

The two high-performance QR1700 and QR2100 shredders have been specially developed for pallet manufacturers and the wood working and processing industry with a throughput of up to 30 loose cubic meters per hour, representing a new class of single-shaft shredders. The QR models cover a drive power range from 55 to 180 kW and cutting unit widths of 1700 and 2100 mm. "Intensive collaboration with our customers throughout the entire innovation process was a key factor in the success of this project," says Stefan Pischon, Head of R&D at UNTHA. "All the technical features are based entirely on the wishes and needs of experienced users and thus offer real added value." These features include not just the robust, universal cutting unit and indestructible body but also the maintenance-free pusher technology and, first and foremost, the resilient drive system that comes with a safety coupling. Unlike conventional units, the QR class does not require a shaft stub, as the gear is integrated into the rotor. This reduces the risk of costly repairs significantly. Special mention should also be made of the multi-functional flap that allows quick and easy access to the cutting chamber, efficient emptying of the hopper and fast removal of foreign objects.
