Airless Hydrocarbon Solvent Cleaning Systems

State-of-the-Art Airless Hydrocarbon Solvent & Modified Alcohol vapor degreasing system

Compared to the competition, our Airless process offers unparalleled performance and compliance with all federal and state regulations. Baron Blakeslee utilizes vacuum technology in our solvent extraction systems in four primary ways:

• Initial Vacuum Process : After loading parts into the Airless Vapor Degreasing System, the door is then closed and sealed. The air within the degreasing chamber is evacuated to achieve pressure of less than 1 torr.
• Release of Solvent and Vapor Once the process chamber is under vacuum, pressure may be equalized to the Vapor Supply Tank which fills the process chamber solvent vapor. Through this process, solvent vapor reaches every surface of the part and is not inhibited by the presence air. Hot solvent maybe be pumped into the process chamber from the vapor supply tank, and then pumped back to the vapor supply tank. Additionally, cool distilled solvent maybe pumped to the process chamber from the Storage Tank, which ultimately pumped back to the Vapor Supply Tank. Depending on options selected, filtered solvent may be sprayed within the process chamber, or ultrasonics may be used to enhance cleaning. Rotation or tilting of baskets to enhance cleaning and drying is another optional feature.
• Cleaning by Condensation: Condensation of solvent vapor heats the parts during the cleaning process. The parts are then cooled and rinsed with liquid solvent to remove deposits. This cleaning and spraying cycle can be repeated several times, based upon operator selection, until the cleaning process is completed.
• Solvent and Vapor Recovery: During the vapor recovery process, the hot solvent vapor is removed from the process chamber to the heat exchanger to be condensed. From there, it is returned to the Storage Tank.
• Restoration of Atmospheric Pressure: In the final phase of operation, the process chamber is equalized to atmospheric pressure. Once atmospheric pressure is achieved, the operator can safely open the door and remove the clean, fully dried parts. Due to the unique methods used, there is no solvent odor or exposure risk to the operator/environment.
  The dirty solvent that was moved to the Vapor Supply Tank during the cleaning process is then distilled to eliminate any contaminants. This is done in two ways:
• Automatic: Automatic distillation occurs periodically during each cleaning cycle when the vacuum package is available (When the process chamber is not being decompressed).
• Deliberate: The operator may initiate a distillation cycle as desired based on process requirements.
