With more RS shredders in operation worldwide than any other UNTHA machine, this four shaft technology transformed customers’ volume reduction, material liberation and recycling possibilities. And thanks to continued innovations, this advanced generation shredder remains world class.
Pre-shred and re-shred your materials in a single pass, for meticulous particle homogeneity, from 15-100mm.
Tailor your loading aperture, shredder speed, torque, cutting systems, screen and sealing variants, for the perfectly customised machine, that entirely satisfies your specification.
Engineered for high availability and operational longevity – even when faced with unshreddables – the RS can shred for decades. Cutter refurbishment and shredder rebuild services are also available.
Equipped for continuous multi-shift operation up to 20 tph, this cleverly designed ergonomic shredder is efficient, safe and easy to maintain.
With a number of RS models in the fleet, talk to us about the shredder configuration that’s right for YOUR requirements. We can also offer trials and reference site visits for the complete ‘try before you buy’ experience.
This is by far UNTHA’s most versatile shredder, however complex the application:
Thanks to its precise, defined and configurable shred, the RS is perfect for:
The reliable and rugged RS30 and RS40 shredders were developed for a wide range of applications and have a proven track record for decades. These compact machines can stand alone or be integrated into comprehensive systems. Power (kW) 11 – 44 Cutting chamber (mm) 450 x 700
The mid-range RS shredder models are engineered to withstand pressures from even the toughest applications. With their proven reliability and resistance from unshreddables, they excel in a wide range of applications. Power (kW) 44 – 150 Cutting chamber (mm) 750 – 1,020
The RS150 is the largest 4-shaft shredder that UNTHA has manufactured. Designed specifically for extreme applications where operators require very high throughputs, low operating costs and high availability. Drive power (kW) 4 x 78 Charging hole (mm) 1,500 x 1,260
An intuitive 5\" colour display allows user friendly shredder optimisation, the selection of pre-defined programmes, performance monitoring and fault finding/resolution, for easy maintenance and continuous shredding.
Engineered to perform in challenging situations, RS cutting discs are resistant to non-shreddables, and with a long service life, are designed for intense, continuous operation for maximum uptime and ROI.
A functional design protects the machine components from dirt, and the torsion resistant steel frame construction provides a stable, low-vibration base. Cutters are manufactured for a long service life, with cutter reconditioning and even complete shredder rebuild services available, to really prolong the lifespan of your asset.
The automatic detection and switch-off function plus auto-reverse capabilities protect the shredder from damage in the event of motor overload. The machine will also switch off when idling to protect energy consumption and costs.
Staggered start up of the two motors reduces current and power peaks. The motor unit’s simple design also reduces susceptibility to faults and minimises maintenance costs.
The quick-change screens and cutters can be configured to customers’ specific requirements, for a homogenous shred and high quality, on-specification output at high throughputs.
The slow speed, high torque cutting system ensures a robust shred, for maximum safety and uptime, with low noise, dust and wear.
No need to wait – with selected shredders available for immediate dispatch, we deliver fast. Which means streamlined operations can get started with minimal downtime, for maximum efficiency.
Options in the new RS ‘tech pack’ include a longer-lasting mechanical seal to protect bearings, wear plates for added resilience against aggressive materials and digital oil level monitoring with automatic switch off. Optionally pretensioned cutting discs to prevent damage from unshreddables, and shaft ventilation to reduce contamination within the cutting system, are also available.
Optional extras include customer-specific feed hoppers, machine frames, discharge feed systems, hydraulic ram to help shred particularly bulky or tricky materials, suction hood with or without screw conveyor, and more.
We have hundreds of cutters, screens and other OEM parts in stock and available for immediate UK dispatch.
The RS shredder integrates easily with other technology. If you’re interested in an end-to-end solution inclusive of ancillary equipment talk to us about what’s possible.

"The UK’s WEEE recycling capabilities are continuously improving, however, the focus is usually the processing of metallic content. We’re therefore partnering with WEEE and scrap metal handlers, to tackle the 50% mixed plastic that typically remains once redundant appliances have been shredded. This still has a significant resource value, which often isn’t realised in the UK. UNTHA shredders make the job of our downstream technology so much easier - we’re able to segregate a further 3-5% clean metal from the floating table which boosts our revenue stream. Our site is attracting a lot of attention, particularly on social media, so we’ll continue to be very vocal when it comes to what we can do. We even encourage people to come and take a look!”
Yu Lin Wang, CEO
“We had heard that UNTHA shredders are valued for their longevity and reliability, which is something we value as a company. We therefore arranged a trial with a small sample of material, to see if the technology could tackle our input material. Impressed from the outset, we then arranged a second ‘shred test’ to see how the machine performed with a full load. But we don’t want to stop there – already we’re thinking about the creation of additional dedicated bulky waste recycling lines, in other parts of the country.”
Iain Bell, UK sales and purchasing manager
“I knew we needed a robust solution with proven media and data destruction capabilities. As soon as I found the RS30 and spoke to the team’s confidential waste experts, I made my choice. This technology ticks all the boxes – operational simplicity, high throughputs, precision particle sizing, customer support services, justifiable capital outlay and minimal wear costs”
Toby Manchip, managing director
“We’ve worked hard to develop systems that can transform complex material streams into reusable and resaleable products. With 20 years’ experience in this industry, I knew from the outset that I wanted an UNTHA shredder to lay at the heart of this operation.”
Paul Kinley, managing director
“This is our first UNTHA machine – in fact it is the first processing machine we’ve ever bought. It will completely revolutionise our approach to recycling because we’ll soon be able to liberate all of the materials from the streams we process. This means more material going back into the industry for reprocessing, and more revenue yield for our business. “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 from such a heavy duty machine of this size.”
Tony Hughes, then managing director
“The RS100 enables us to size-reduce, liberate and produce a saleable finished product for remanufacturing.”
Rob Fluckiger, managing director
“We have six UNTHA shredders in operation at our automotive interior parts plant, and we keep coming back for more. We trust UNTHA as we know they are reliable, and their solutions are of an extremely high quality.
“With our latest RS30 purchase, we opted for a used model, as we already knew what we wanted. It also meant we were able to get the high-performing equipment at the heart of our operation even quicker.”
