Throughout the world, the name Gneuss stands for innovative technology at the highest level for the filtration of polymer melts. At this year´s Achema, Gneuss will present its new, energy efficient MRS extruder, design enhancements to the established range of Rotary Melt Filtration Systems and its environmentally – friendly range of melt temperature and pressure sensors .
1. Rotary Filtration Systems
1.1. The RSFgenius Melt Filtration System: fully automatic filtration for the highest demands
This Filtration System has set the standard for self-cleaning and process–constant melt filtration since its introduction over 10 years ago. The efficiency of its self–cleaning system (up to 400 automatic re-uses of the filter elements) and the extremely low melt loss through back flushing remains unrivalled.
Additionally, the RSFgenius offers pressure-constant operation +/- 1,5 bar, extremely low polymer loss through back flushing and a minimised residence time of the polymer melt.

The RSFgenius represents the ultimate performance which can be offered by any melt filtration system. In most cases, the return on investment is extremely quick.
1.2. The SFXmagnus Melt Filtration System: process-constant operation with low investment costs
The SFXmagnus offers an unmatched performance spectrum at a low investment cost. It is particularly suited for applications whereby process constant and/or pressure constant operation is important, but self-cleaning is not absolutely necessary due to relatively long intervals between filter element changes. This system further characterised by its simple, safe and easy operation, its completely encapsulated design which completely prevents external influences such as airborne moisture. Further, the rheologically streamlined flow channels ensure an extremely short residence time of the polymer melt in the screen changer.
With the development of the large area Rotary Filtration System „SFXmagnus-D“, Gneuss can now offer a system which – due to the drastic enlargement of the filtration area to 1,74 – is a particularly attractive solution for the filtration of high viscosity polymer melts in large scale applications (for example polymerisation processes).
2. The MRS Extrusion System: Unique Polymer Devolatilising Technology
Gneuss will also show a further highlight: a demonstration model of the new type of extruder developed by Gneuss. Since its introduction in 2007, this extruder has set new standards with regard to the degassing or devolatilisation of polymers.
The MRS Extrusion System: Unique Polymer Devolatilising Technology
| The patented MRS extruder is based on a multiple screw system consisting of a single screw drum with satellite screws provides an extremely large and fast changing melt surface for unmatched degassing or devolatilising performance. The MRS extruder ensures the processing of undried PET flakes or chip/pellets to sheet, fibres or strapping tape with a simple vacuum of only 20 – 40 mbar. |
This system also permits the extremely efficient extraction of solvents or other problematic volatiles during plastics manufacture or processing. In addition to the excellent degassing or devolatilising properties, the simple and rugged design of the MRS makes it the ideal machine for the processing of heavily contaminated materials. In combination with the Gneuss Online Viscosimeter, continuous monitoring and control of the melt viscosity is made possible.
