Vapor degreasing

Process

The acting principle behind the vapor degreaser process is that the solvents will dissolve the contaminants on the workpiece and remove them by dripping off the part. A basin of solvent is set up with a heating coil to bring the solvent to boil. As the solvent evaporates it rises to the fill-line in the chamber, above which is the much lighter air. This contains the vaporised solvent in a closed space where the workpiece is placed. The solvent condenses on the more frigid workpiece and the now liquid solvent dissolves the greases on the part. With the impurities contained in the liquid beads, the solvent runs off the part. FMF systems are designed to capture and reclaim this solvent, making the process much more economical.

Benefits

• Can be used on electronic parts to remove excess oil, grease, wax and other non-water soluble particles because water is not used.
• Used where water-based system are impractical.
• Cleans and prepares part surfaces for various finishing processes like painting, welding, soldering, and bonding.
• Issues of part oxidation and water spots are not present.
