RINGEXTRUDER

VENTING & DEGASSING

Process Technology

High performance degassing in combination with vent ports or vent stuffers.

The surface/volume ratio of the RingExtruder RE® offers significant advantages for melt degassing applications as compared to other process technologies.

Multiple staged vacuum ports and long L/D in a small footprint enable the RingExtruder RE to far surpass the devolatilization efficiency of twin-screw extruders for these applications.

Degassing under vacuum can be accomplished using top and/or side vents to reduce vapor velocity

Devolatilization

The split up of the material flow into 12 sub flows – one per screw channel – creates a huge surface. This is the reason for the outstanding degassing capacity of the RingExtruder RE®.
