Confidential waste destruction,
however complex your requirements


A high capacity confidential waste shredder, the industry-acclaimed UNTHA RS100 guarantees robust, configurable and precise classified material destruction. Confidential waste is pre and post shredded in one single operation, and if the material does not immediately fall through the RS100’s interchangeable screen, it is re-fed into the cutting system and the shredding process continues. This means that the client has utmost peace of mind that particle consistency will be guaranteed, every time.

Why are these four shaft shredders so renowned?

The industrial shredders within the four shaft UNTHA RS series – the RS50, RS60 and RS100– are incredibly configurable, meaning the machine can be customised to suit the confidential waste scenario concerned. UNTHA UK’s team of experts can work with you to determine the optimum speed, driving power, cutting hole, torque, cutting system configuration, perforated screen and sealing variant, for your waste or recycling process.

Expectations within the arena of confidential waste and secure data destruction are understandably incredibly high, due to the stringent parameters that govern the processing of such materials. But UNTHA’s industrial confidential waste shredders and product destruction shredders have proven a safe and dependable solution every time, whilst at the same time reaping numerous cost efficiencies for clients too.

The reliability of this heavy duty yet flexible machine means the RS100 is perfect for a range of tough applications including refrigerators, mattresses, cement asbestos boards, radioactive waste, carpets and rugs, mechanical waste and medicinal waste.

See the RS100 security shredder in action

The UNTHA RS100 can handle an array of bulky, complex and heavy duty confidential waste applications. But ‘seeing is believing’, so why not watch this short demonstration video to see the four shaft shredder in action? Alternatively, if you want to put this machine through its paces, why not organise a trial in our North Yorkshire test centre, and see how the RS100 handles your own materials?

BPR is now generating revenues of more than £100 per tonne of shredded paper and expects to see a return on its investment in four years.
We sought a reliable shredder that could produce a small yet consistent particle size. Thankfully the design and functionality of the RS100 met our specification entirely, whilst presenting a number of additional operational benefits like high throughput, a low level of dust and vibration, and energy efficiency.
