Vapor degreasing

Process

• Several tanks for solvents and rinsing
• Having a solvent spray to coat the workpiece prior to entry into the chamber to speed up the process and to allow for more complex parts to be cleaned. The spray must be below the vapor line.
• Vacuum degreasers

  Benefits

• n-propyl bromide based solvents for vapor degreasing, in comparison to other solvents for vapor degreasing, are environmentally friendly. nPB solvents are non flammable, non chlorinated, U.S. EPA SNAP approved, non hazardous waste, and non ozone layer depleting. However, "Exposure to 1-BP can cause irritation and can damage the nervous system. Neurologic effects can appear as headaches, dizziness, loss of consciousness, slurred speech, confusion, difficulty walking, muscle twitching, and/or loss of feeling in arms and legs."
• 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.
• With vacuum degreasers, there is no solvent emitted. However they have a high cost and low production rate.
