Vacuum Cycling Nucleation Agitation Benefits

Vacuum Cycling Nucleation Agitation Benefits:
VCN can be much more effective than ultrasonics especially for small delicate parts or complex parts with difficult to reach internal surfaces. Below is a comparison of some areas where VCN can be more effective.

Ultrasonics

VCN

Internal Cleaning NO YES Ultrasonics can’t penetrate solid surfaces.
Damage to Delicate Parts YES NO Ultrasonic bubbles are small and aggressive to shock contaminant from a surface. VCN bubbles are large and gentle to move fluid throughout a part.
Load Dependent YES NO Solid surfaces adsorb ultrasonic energy. The larger the load, the greater the energy dissipation and the more energy required.
Uniform Treatment NO YES Ultrasonics is adsorbed on the surfaces closest to the transducers. Parts located on the inside of a basket can receive little to no ultrasonic energy.
Targets Contaminant NO YES Vapor needs a solid surface to begin forming. Vapor nucleates in regions of high surface area to fluid volume. VCN likes to create vapor in tight areas.
Chemical Delivery to Surface NO YES When a fluid has been loaded with contaminant, the cleaning process either slows or ceases. VCN replenishes all areas with fresh cleaner in seconds.
Effectiveness With Solvents LOW HIGH Ultrasonics likes to operate at temperatures low enough to make sure vapor formed collapses as opposed to evaporating. Solvents are often used at the boiling point.
Concentrations Required HIGH LOW Since VCN continuously replenishes cleaner at a surface, lower concentrations of surfactant is required to accomplish effective cleaner.
Effective Rinse Method NO YES At the end of cleaning, surfactants are now the contaminant. Using VCN with your rinse water removes surfactants from your surface quickly and efficiently.
