Solvent vacuum degreasing is a highly effective cleaning method used to remove contaminants, such as grease, oil, and other residues, from various surfaces. This process utilizes hydrocarbon-based solvents or modified alcohols as the cleaning agents. It is particularly suitable for parts and components that cannot be effectively cleaned using aqueous-based methods or where water-sensitive materials are involved.

How Solvent Vacuum Degreasing Works

1. Loading: The parts to be cleaned are placed inside a sealed chamber or basket within the vacuum degreaser machine.

2. Vacuum Creation: The chamber is evacuated to create a vacuum, removing air and creating a low-pressure environment.

3. Solvent Introduction: The selected solvent, such as a hydrocarbon-based solvent or modified alcohol, is introduced into the chamber. The solvent vaporizes and fills the chamber, effectively permeating the surfaces of the parts.

4. Degreasing Cycle: The solvent, in its vapor state, condenses onto the parts, dissolving and removing contaminants from the surfaces. This process is facilitated by the low-pressure environment, which enhances the cleaning efficiency.

5. Rinsing: After the degreasing cycle, the chamber is re-pressurized, causing the solvent to evaporate and leave the surfaces of the parts.

6. Drying: To ensure complete solvent evaporation, a drying cycle is typically employed to remove any residual solvent from the parts.

Solvent vacuum degreasing is a versatile and efficient method for removing contaminants from various parts and components. Its ability to provide thorough cleaning, compatibility with water-sensitive materials, and flexibility in solvent selection make it an essential process in many industries.
