Vacuum Ultrasonic Cleaning

Ralsonics’ vacuum powered multistage cleaners are innovative systems specifically designed for intricate parts with blind holes and other unique features. This method of precision cleaning is significantly more effective than regular ultrasonic cleaning. The entire cleaning process is performed in a vacuum environment.

How vacuum works for cleaning and drying

  1. Intricate parts are placed in a basket inside vacuum chamber.
  2. Vacuum is started. Air is removed from the system.
  3. Cleaning liquid is introduced. Since no air is present in the system, the liquid is pulled into all the blind holes and intricate features.
  4. Pulled into all the blind holes and intricate features.
  5. With vacuum, liquid is covering 100% of component surface area. Thus, ultrasonic cleaning is super effective.
  6. For part drying, vacuum conditions, drastically reduces the boiling point of the cleaning fluid.
  7. This ensures very fast conversion of liquid to vapor which is removed from the system leading to super-fast and effective drying.
