New generation of extruder degassing systems

New generation of extruder degassing systems
The new generation of PLASTEX vacuum systems is ready for Industry 4.0

Busch Vacuum Solutions present the latest generation of PLASTEX vacuum systems for extruder degassing. The new PLASTEX vacuum systems can be programmed and monitored via a display. They are fully connected in order to exchange data with the extruder control system and can be operated directly via the extruder. The fact that all components are connected means that PLASTEX vacuum systems are ready for Industry 4.0. The degassing system is controlled as required by a frequency-controlled drive motor. This means that the programmed vacuum level is precisely maintained – the energy saved in the process is a further benefit.
In recent years, PLASTEX vacuum systems have become widely established for degassing the melt in the screw zone of extruders. The model presented below is equipped with a MINK claw vacuum pump. These vacuum pumps operate dry, i.e. they do not require any operating fluids such as water, which can lead to high costs for treatment and disposal.
With the new generation of PLASTEX vacuum systems, Busch now impresses with further benefits. Thanks to the demand-dependent control and the option to adjust the vacuum level precisely to the material to be extruded, the extruder and the temperature conditions, it is possible to reproduce product quality without having to readjust the vacuum level manually via valves during the process. PLASTEX vacuum systems are available in different configurations and sizes. They are suitable for both compounds and master batches. They can be used to degas polyolefins such as PP/PE, EVA, PBT, ABS, EVOH or POM. Even the degassing of recycled material does not pose a problem. A flushing device allows to clean the vacuum pump after or during the process. It is also possible to program the cleaning intervals and the dosing of the cleaning agent.
