Crest Ultrasonics' vacuum drying systems are a proven effective method for drying

parts that trap water because of complex geometries or absorb water onto the surface.

Vacuum drying is usually used as a secondary drying method to remove trace

amounts of residual water. Vacuum drying is done by placing parts in a heated

vacuum chamber to flash off the water. The system is typically used in an in-line batch

configuration.

Vacuum drying is accomplished by creating a vacuum atmosphere that reduces the

vapor pressure of water molecules on the substrate being dried. The water rapidly

reaches its boiling point and it "flashes'1 off the surface. By pulling a vacuum and

thereby reducing the pressure in the chamber, the boiling point of the water in the

chamber is reduced and the water is flashed off the surface.
