Depending on the degree of contamination and volatile substances in the melt flow, different modular degassing units are used. Homogeneous melt without entrapped gas is the result.

Single venting old

Single venting

Designed for light printing and low humidity. The vacuum degassing system includes a vacuum pump and is connected to two venting ports on the extruder.

Double venting C-GRAN

Double venting

Designed for plastics printed, for example, on all surfaces and/or moist plastics.

Heavy duty vacuum pump

High-performance vacuum

In addition to the modular venting unit, a combination of water ring pump and high-performance vacuum pump runs in order to increase the vacuum performance (e.g. PET processing).

Combined venting

Combined venting

For damp materials, e.g. after washing, combined venting unit is used, which consists of an atmospheric and vacuum degassing unit.

Vacuum pump with closed water circuit

Vacuum pump with closed water circuit

Each venting combination can be equipped with a closed water circuit. The fresh water consumption at the vacuum pump is thereby reduced significantly.
