Use Vacuum Dryers in Various Areas
Chemical Processing
Vacuum dryers are ideal for drying oxidation-prone chemical materials or those containing organic solvents. In coating production, vacuum drying removes solvents, recycles them, and prevents oxidation, ensuring the coating’s quality and performance.
Electronic Products
Vacuum dryers are ideal for drying moisture- and oxygen-sensitive products, such as electronic components and battery materials. For instance, lithium battery electrodes require vacuum drying to protect performance from moisture and oxygen.
Pharmaceutical Products
Vacuum dryers are ideal for drying heat-sensitive drugs and biologics, such as enzymes, vaccines, and proteins, by removing moisture at low temperatures while preserving their activity.
