Internal Penetration of Parts

Bearing Cleaning Demonstrates the Power of VCN

Like the initial vapor bubble formation in a boiling pot of water, VCN bubbles like to form in tight areas like the crevices in the pot where water begins to boil. Vapor bubbles expel fluid and contaminant from the area and collapsing bubbles draws in fresh fluid. The cycle is in seconds so that fluid turnover in the part’s internal surfaces is rapid. The agitation produced during vapor formation works to remove particles and surface contaminants.

1. Pack your parts. VCN pressure is uniform throughout the chamber even under adjoining surfaces.

2. Clean at lower temperatures if your part has sensitive materials.

3. Clean in a controlled environment. Keep out ambient surroundings.

4. Vacuum dry to prevent spotting. Reduce solvent loss or use lower surfactant concentrations for cost savings.

5. Vacuum distill to concentrate waste and recycle solvent for additional operating cost savings.

The linked video shows how VCN can form vapor bubbles in very small spaces. Devices that never before could be cleaned, can now be cleaned, sterilized, and dried using the VCN process. VCN at low vacuum or low temperature can reveal the primary vapor bubble generation location in a part. A bearing is seen in the video.
