Vacuum improves the drying rate significantly for very dense products and is highly effecve in the recovery of toxic constuents, valuable solvents or fragrances. It is essenal for producing the low temperatures required to prevent degradaon and improve product quality and viability. As experts in vacuum technology, Edwards has a full understanding of drying processes and the importance not only of pump sizing and selecon for effecve solids and liquid handling but also the challenges presented by corrosive, flammable, explosive and poisonous chemicals. Edwards CXS pumps are ideally suited to vacuum drying processes in the fine chemicals, food and pharmaceucal industries.
