ROEX: an eco-friendly extruder
Less energy.
More power.
The extruder is the biggest power consumer within an extrusion line. Every optimization in this area therefore has a high impact on the overall energy consumption of the extrusion line.
The energy demand of an extruder is particularly influenced by the design of its processing unit (feeding section and screw design), as well as by the heating and cooling of the complete extruder. With the development of the ROEX extruder series, we were able to make significant optimizations and achieve considerable energy savings. For the same output, ROEX extruders consume roughly a quarter less energy compared to conventional extruders.
The latest extruder drive technology
Innovative direct motor drive concept for your extruder
The compact motor gearbox (CMG) is the latest extruder drive technology. Within the housing of the CMG, there is a motor system symmetrically placed around one central planetary gear. This positioning makes very uniform load transmission possible, resulting in
- lower noise emission
- lower space requirement
- lower energy consumption
- longer machine lifetime
Stable process for your extrusion line
Higher linearity over the whole operating range
In addition to their higher output and stable melt pressure profile, ROEX extruders have the advantage of a high linearity of output over the entire range of operation. That results in stable product dimensions over the complete operating range of the extruder.
These great features make a ROEX extruder the heart of every extrusion line.
Interchangeable, water-cooled feeding sections
Higher flexibility with your
ROEX extruder
ROEX extruders are equipped with an integrated water-cooled feeding section. Together with the appropriate processing unit, the influence of counter-pressure fluctuations is reduced to a minimum compared to a conventional extruder. The result is a consistently high-quality final product and a significantly higher production speed.
Regardless of the demands that may arise in the future – thanks to Rosendahl’s interchangeable feeding sections, you can easily adapt your extruder to new materials anytime. That gives you the right amount of flexibility in manufacturing your products – today and tomorrow.
- Stay flexible for new product designs
- Save on maintenance costs
Independent water-cooling system for every ROEX extruder
Both the compact motor gearbox and the feeding section are water-cooled to keep them temperature-controlled. Additionally, this system avoids contamination in these water channels. The chilled plant water is connected to the heat exchanger. There is no contact between the plant water and the coolant in the separate cooling system.
- For easy cleaning of the water channels
Special design of extruder screws
Optimized screw geometry
The screw plays the key role in the extruder. The better it works, the better the product you sell. We are constantly working to improve our processes and have the right standard screws for your typical products, as well as for specific processes: universal screws, low-compression screws, product optimized screws.
ROEX extruders are designed to process a wide range of materials, such as PE, PP, PVC, LSF-HFFR, PA, PBT, XLPE, FEP, ETFE. We also provide machines for high-quality physical foaming and silicone extrusion lines.

Thinking about upgrading your extrusion line?
Simply integrate a ROEX extruder into your existing extrusion line. ROEX extruders are equipped with their own PLC with two integration methods:
- Total integration in the existing extrusion line control via fieldbus (Profibus, Profinet, etc.)
- Integration as a stand-alone version with a touch panel and hardware interface
