Vacuum Cycling Nucleation Agitation Cleaning 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.
