MAAG’s CSC-C large scale screen changer with candle filter elements is the right choice if short melt residence time, small footprint and a simplified candle change are required. Depending on the polymer type, melt viscosity, reactor throughput, and filter fineness, the screen changer size and number of pistons are customized to the application. The patented design allows the use of pleated micronex® candle filter elements with fiber metal felt (FMF) media, or cylindrical Multinex candles filter elements with interchangeable filter sleeves.

Continuous CSC-C screen changers from MAAG, with their robust and leak-free operation, meet the highest quality standards. The sturdy design is based on the proven double or quad piston design that operates reliably without any additional seals. On the filter inlet side, rheologically optimized fl ow channels divide the melt stream into the 2 or 4 pistons in equal parts. Downstream of the candle filter elements, the cleaned partial melt streams converge again and flow out of the filter housing as on single polymer stream.

MAAG large scale screen changers can be installed for vertical or horizontal melt flow directly at the reactor discharge melt pump or pelletizer booster melt pump. The direct assembly of the screen changer to other process components without additional piping ensures the shortest possible line length and melt residence time between the extruder or reactor and the pelletizer.
