Variable Temperature Cleaning System

This variable-temperature cleaning system employs perchloroethylene (PCE) at operational temperatures reaching up to 230°F. The system fully evacuates ambient air prior to solvent introduction into the chamber, facilitating processing at temperatures below the solvent’s standard boiling point. Cleaning is conducted under vacuum conditions to ensure comprehensive coverage of all internal surfaces. Utilizing a proven effective solvent is recommended, and for applications requiring lower temperatures, the vacuum system can be adjusted to lower the temperature to approximately 150°F.

The unit predominantly operates using PCE at a temperature of 200°F. It replaced an open-top vapor degreaser that processed twelve transmissions over an 8-hour period. Currently, all 12 transmissions are loaded simultaneously and subjected to a consolidated cleaning cycle lasting approximately 30 minutes.
