Vacuum Processing Systems

Vacuum Cycling Nucleation (VCN) is an advanced cleaning technology that effectively targets complex geometries and dificil-to-reach regions, achieving cleaning speeds up to ten times faster than conventional methods. The process involves applying a vacuum to a sealed chamber to induce liquid evaporation. This evaporation facilitates the nucleation of vapor bubbles on the surfaces of the solid component. Due to the preferential formation of bubbles in high surface-area-to-volume regions, vaporization predominantly occurs within confined, nested, or porous structures, ensuring comprehensive internal cleaning. During the cycle, contaminated liquid is expelled from internal cavities, and fresh cleaning fluid is drawn back in when the vacuum is released.

Our aqueous cleaning and solvent liquid soak systems operate under vacuum conditions to ensure comprehensive coverage of all recessed areas and internal surfaces during the cleaning process. Techniques employed in open-top vapor cleaning systems, such as immersion, sonication, superheating, drying, heated immersion, and clean immersion, are directly applicable to our airless systems. The aqueous cleaning process occurs within a vacuum chamber, providing precise process control and allowing for optimization of parameters. For example, ultrasonics at lower temperatures prevent cavitation and maintain cleaning efficacy, whereas increased temperature enhances cavitation activity. Optimal cavitation in ultrasonic cleaning is achieved by reducing chamber pressure. All ultrasonic degreasing units incorporate vacuum drying, with optional advanced processes such as Vapor Phase Cleaning (VPC).
