What UNTHA shredding technology does

UNTHA shredding technology GmbH is an Austrian, privately held manufacturer of industrial shredding equipment, founded in 1970 in Kuchl, Austria, by Anton Unterwurzacher, who invented 4-shaft shredding technology in the 1970s-1980s. The company designs, engineers, and produces 100% of its machines in-house ("Made in Austria"), selling a portfolio spanning four-shaft RS-class shredders, single-shaft XR-class high-performance shredders, two-shaft ZR-class primary shredders, compact LR-class wood shredders, LRK plastic shredders, the PS pallet shredder, mobile crawler-mounted variants, and the UNTHA Power Core autonomous power solution. Its proprietary Eco Power Drive uses a water-cooled synchronous motor delivering up to 75% energy savings versus diesel or hydraulic drives, and the GENIUS condition monitoring and Smart Feed Interface (jointly developed with SENNEBOGEN) provide predictive maintenance and machine-to-machine communication.
