Washer Module: Vacuum Dry

The vacuum dry module is part of a complete industrial part washing system. It is essential when subsequent processes, such as leak testing, require complex cast parts to be dry inside and out.

The vacuum dry is a secondary drying process, typically following a primary air knife blow-off process.

After loading the clean part, the vacuum bell chamber closes, creating a sealed environment. A vacuum pump reduces the pressure inside the bell chamber, vaporizing moisture from part surfaces, internal cavities, and blind holes, ensuring absolute part dryness.
