Gneuß at Fakuma 2009

Throughout the world, the name Gneuss stands for innovative technology at the highest level for the filtration of polymer melts. At this year´s Fakuma, 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.Content 1. Rotary Filtration Systems 1.1. The RSFgenius Melt Filtration System: fully automatic filtration for the highest demands 1.2.

Gneuss Sensors: Accurate Measurement of Polymer Melt Pressure and Temperature with Reilable, Environmentally Friendly Sensor Technology 1. Rotary Filtration Systems1.1. The RSFgenius Melt Filtration System: fully automatic filtration for the highest demandsFiltration System RSFgenius (shown adapted to a melt pump)   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.Other characteristics of the RSFgenius are: Applicable for all types of polymers Active filtration area up to 5.140 cm² Filtration as fine as 1 µm No effect on the process during filter changes.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.2. The MRS Extrusion System: Unique Polymer Devolatilising TechnologyGneuss 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 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.   MRS extruder with 8 satellite screws in extrusion drumIn 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 Viscometer, continuous monitoring and control of the melt viscosity is made possible.3. Gneuss Sensors: Accurate Measurement of Polymer Melt Pressure and Temperature with Reilable, Environmentally Friendly Sensor TechnologyGneuss Sensors in Detail   Thanks to a major expansion of its product ranges, Gneuss offers environmentally – friendly solutions for practically every melt pressure, temperature and viscosity measurement application in the plastics processing industry. The unique, mercury -free NTX technology permits accurate measurements which previously could only be achieved using mercury. The most significant new features are: Highly sensitive reaction with maximum resilience High accuracy: up to 0,1 % of measurement scale Excellent long term reproducibility of measurement values Mercury - free melt pressure transducers with new NTX technology Explosion proof design 2 – wire 4 to 20 mA Optional CAN-open or HART communication High temperature sensors for up to 500°C Strengthened diaphragms from non - standard materials for special requirements G-coating: special surface treatment for better performance with sticky media Pressure sensor with auto – 0 function Patented melt pressure transducer with heated tip for excellent sensor longevity with sticky materials with strong cooling shrinkage properties. Revolutionary performance with critical media. Melt temperature sensors with ceramic sleeve for insulation of the measurement tip in order to prevent the influence of external heat sources DIN ISO 9000: 2001, ATEX, GOST R, measurement equipment and RTN- approval (ATEX , not ATEX-QS)
