Compact screen changers for applications with frequent material and/or colour changes.
KSFx2 screen changer with double active area
The KSFx2 Filtration System is characterized by rheologically optimized melt flow channels absolutely free from dead spots. The channels are matched individually to the respective filtration task. When the pressure upstream of the filter increases due to contamination of the screen and the selected pressure value is reached, a screen change is carried out automatically.
During screen changes, polymer flows briefly over 3 screen cavities, thereby avoiding pressure spikes and consequently avoiding process disturbances. It is possible to remove the breaker plates during screen changes and replace them with clean plates. This is especially important for thermally sensitive materials, to make sure that always a 100 % clean cavity and breaker plate enter into the melt flow.
