4. Airless™ Vacuum Cleaning Systems Standard Precision Models Model 1200 Model 1800

5. Serec Airless™ Vacuum Cleaning Systems: • Cleaning Systems are distillable solvent cleaning systems where the process occurs in a vacuum chamber for the ultimate in efficiency • Once loaded, the work chamber door is closed, and a vacuum is created. • Solvent / vapor are transported into the work chamber as required by the cleaning process • Vacuum enhances solvent cleaning efficiency, performance and ensures complete drying. • Cleaning process is consistent, repeatable and environmentally responsible. • Provides the lowest utility consumption, environmental impact and operational cost of any cleaning process.

21. Serec Process Flow • Cleaning Process • Load parts chamber and close lid. • Evacuate air from process chamber to one torr and out of the unit using the vacuum package. • Equalize pressure between the degreasing chamber and the vapor supply tank. • Fill the degreaser with solvent from the vapor supply tank (VST) (submerge parts) and soak. May apply recirculation soak/flushing. • Ultrasonic energy may be applied to enhance cleaning. (Optional). Also, basket rotation may be applied. (Optional) • 5. Drain cleaning chamber and return solvent to the vapor supply tank. Note, steps 4 and 5 can be repeated as desired.(Optional) • 6. Spray pure cold solvent from the storage tank. (Optional) Note, excess solvent is collected in the vapor supply tank. • 7. Vapor degrease\heat parts with vapor from the vapor supply tank. Note, excess solvent is collected in the vapor supply tank. • 8. Vacuum dry chamber and parts to one torr using the vacuum package. • 9. Return chamber back to atmospheric pressure. • Distillation Process • Contaminated solvent from the vapor supply tank is transferred to the distillation vessel on an as need basis. • Solvent is distilled and collected in the storage tank during the cleaning process cycle when the vacuum package is available. Distilled • solvent is required to replenish the vapor supply level and supply pure solvent spray for the on coming cleaning cycle. • 3. Removed contaminated solvent from the vapor supply tank is replenished by pure distilled solvent from the storage tank to maintain • high solvent purity levels in the vapor supply tank.

29. Benefits Of Vacuum Technology • Solvent Emission ReductionInitially the air in the cleaning chamber is evacuated so that the solvent and the air are not interfaced with each other to eliminate the solvent emissions. • De-gassing the SolventWhen the solvent is placed under vacuum, the air dissolved in the solvent is eliminated to enhance the ultrasonic power —this means cleaner parts. • Drying the Parts Completely In the vacuum drying process, the vacuum created in the cleaning chamber depresses the boiling point of the solvent: becoming 75% of its boiling point at atmospheric pressure. The higher the vacuum, the lower the solvent boiling point. The heat capacity of the parts helps boil the solvent and the evaporated vapor is recaptured and recycled in the system.
