Unopex Vacuum Evaporators

Gentle evaporation of heat sensitive products

Evaporation technology is a process of separating substances by means of thermal energy. It is the most common and the most applied technique for concentration. In herbal processing, evaporation plants are often integrated between the extractions and drying processes, they can also be operated as individual plants.

Unopex Vacuum Evaporators are batch or continuous unit operating at atmospheric pressure or under vacuum with heating by steam, hot water or thermal oil.

Unopex Vacuum Evaporators are designed for manufacture and install the system you need and our specialists will recommend the system with the most advantages your applications such as pharmaceutical, food and cosmetics.
