Extrusion International 6-2019

PREVIEW 60 Extrusion International 6/2019 Gneuss Filtration Technology will ex- hibit several different models of their patented Rotary Filtration Systems. These continuous filtration systems are characterized by a filter disk on which the screen cavities are locat- ed in a ring pattern. Screens can be changed on the part of the filter disk that is not active in the melt channel, while the production process contin- ues to run without any interruptions or disturbances. The new model SFneos was devel- oped to combine the characteristics of several older models into one sim- ple and cost-efficient solution, offer- ing the following advantages: • Constant pressure guaranteed – even during screen changes • Suitable for most types of polymers and viscosities • Compact design thanks to an en- larged active screen area (up to 2370 cm 2 ) Last but by no means least, Gneuss will exhibit two KF screen changers, a KF 75 with an active screen area of 44 cm 2 and a KF 110 with an active screen area of 95 cm 2 . Gneuss also offers a new semi-con- tinuous model, the CSFprimus. This model is used as a pre-filer, safety fil- ter or in applications with little con- tamination and is characterized by a very large active screen area for its small footprint. Gneuss Extrusion Technology will show a complete Gneuss Processing Unit (GPU) including a second gener- ation Multi Rotation System MRS110 extruder, a fully automatic melt fil- tration system RSFgenius 90 and a new style online viscometer VIS, for the processing of 600 kg/h of undried and uncrystallized polyester (PET). The Gneuss Processing Unit (GPU) has been available for more than a decade now and has proven itself for New Rotary Filtration System SF neos , and more • Simple and safe handling and oper- ation with several screens accessible for screen changes • Very cost effective thanks to its im- proved design The SFneos is the ideal filtration sys- tem for applications that benefit from a continuous, pressure and pro- cess constant screen changer, but that don’t require back-flushing. The SFneos 90 on display has an active screen area of 260 cm 2 . Gneuss’ top model, the RSFgenius, operates with an integrated self cleaning system for very demand- ing applications and highest quality requirements. Screens can be auto- matically re-used up to 400 times and filtration finenesses below 10 microns/1200 mesh are available. There will be different sizes on dis- play, including an RSFgenius 330. It offers an active filtration area of 2150 cm 2 . Patented Rotary Filtration System SFneos
