UNTHA Shredding Technology Gmbh

Reliable Shredding Technology for Residual Timber Utilization - Forestry & Wood

Our reliable wood shredders ensure the production of a homogeneous granulate for your in-house wood chip furnace, biogas plant, biomass co-generation plant and also the production of wood briquettes. Regardless of how you are planning to use the wood chips, we will configure the wood shredder exactly according to your needs. We offer you a large selection of wood shredders with various working widths, rotor diameters and drive capacities. The possible granulate sizes usually range from 12 to 80 mm. Regardless of whether you need a compact, small system or have specific needs, we will always find the right solution for you!

Metal-free wood chips

All our industrial wood shredders produce a high quality granulate for immediate use in wood chip heating systems or the production of briquettes. Metal parts such as nails, screws, clamps or metal fittings are no problem for the cutting system: The metal is shredded together with the waste wood and can easily be removed by an additional metal separation system or a pipe magnet.

3-year carefree warranty

Capitalize on our reliability! We provide a 3-year or 2,000-hours carefree warranty on all our UNTHA wood shredders, depending on which value is reached first.
