Vacuum de-aeration unit for liquid to pasty products
Optimize your product consistency and stability with continuous de-aeration, essential for preventing oxidation and ensuring precise filling volumes in liquid to pasty formulations.

Continuously De-aerates Liquid and Pasty Products
The PUC EVA Vacuum De-aeration Unit from Probst & Class GmbH & Co. KG is a robust solution designed for continuous de-aeration of liquid to pasty products. By utilizing a thin-film distribution system within a vacuum vessel, it effectively releases and removes gases such as oxygen, enhancing the chemical stability and appearance of products in industries ranging from pharmaceuticals to petrochemicals. With capacities up to 10,000 kg/h, it ensures precise metering and packaging. The unit operates fully automated, maintaining product temperature while offering easy integration into processing lines. Constructed for durability and high performance, it meets stringent quality standards, with customization options available to suit specific production needs.
