ZS-EG twin screw side degassing

The performance capability of the ZSK series with a conventional top
vent barrel can be limited in many cases especially in the extrusion of low-viscous melts and extrusion processes with high gas volumes.

The ZS-EG twin screw side degassing from Coperion provides the solution. With its large free cross section for the devolatilization, it keeps the melt in the processing section without product escape even at maximum specific torque of the extruder. Fumes or gases are reliably removed through the axially open screw flights. Increases in the throughput rate of up to 30 % with improved product quality are possible.

The ZS-EG twin screw side degassing is mounted on the side of the extruder either with a mobile frame on casters or with a swivel arm.
