Variable Temperature Cleaning System
This variable temperature cleaning system uses perchloroethylene at temperatures up to 230 F. The unit completely evacuates air prior to solvent introduction to the chamber so as to allow for temperature operations below the normal boiling point of the solvent. The cleaning is performed under vacuum to assure effective cleaning by reaching all internal surfaces. Operating with an known effective solvent is wise and when parts need lower temperatures, this vacuum system can go down to 150 F.
The unit generally uses perchloroethylene at 200 F. The unit replaced an open top vapor degreaser that cleaned a dozen transmissions over an 8 hour period. The 12 transmissions are now loaded all at once and they are cleaned in a half hour cycle. (See also: Performance for an explanation of why this is possible).
