Vacuum Processing Systems

Vacuum Cycling Nucleation (VCN) is a technology that can clean difficult areas and clean up to 10 times faster than any other present cleaning method. The process is accomplished by applying a vacuum to a chamber to evaporate the liquid. The process results in the formation of vapor bubbles on the surfaces of the solid part. Since bubble nucleation tends to occur in areas with high surface area relative to liquid volume, the liquid evaporates primarily in tight, nested, or porous regions, thoroughly cleaning the part’s internal areas. Dirty liquid is pushed out of the internal areas, and fresh liquid flows back into them when the vacuum is paused.

Our aqueous cleaning and solvent liquid soak systems operate under vacuum to ensure that all recessed areas and internal surfaces are filled with liquid during cleaning. All the same processes used in an open-top vapor cleaning system can be applied to an airless system.  Examples include immersion, sonics, superheat, drying, heated immersion, and clean immersion. Our aqueous cleaning takes place in a vacuum chamber, enabling complete process control. This means we can optimize any process. Ultrasonics, for instance, operating at low temperatures will not cavitate and clean as well as when at higher temperatures. In our ultrasonic cleaning machine, a more effective cavitation can be attained by lowering the chamber pressure. All ultrasonic degreasing equipment includes vacuum drying and may include other enhanced processes, such as VCN.
