INTRODUCTION
The Forward Technology F-100 solvent cleaning system is designed for use with non-
flammable performance solvents. These solvents provide excellent cleaning and drying
results. A typical F-100 cleaning system is illustrated below.
F-100 THEORY OF OPERATION
The vaporization and condensation of the solvent is the driving force to move solvent
throughout the system. This process, known as refluxing, ensures that the dirtiest solvent is
concentrated in the boil sump where parts never go. The condensed distillate gravity drains
into the wash sump, which cascades into the boil sump. As parts are lowered into the cleaner,
solvent condenses onto the parts rinsing them. Sonication of the parts, once immersed in the
tank, removes particulate. A final rinse takes place in solvent vapor as the parts are removed
from the process tank. Solvent remaining on the parts volatizes and drops back into the tank
when moved into the vapor zone. This flash of vapor facilitates the drying of the parts. The F-
100 Series equipment typically has a solvent distillation rate approximately equal to the
volume of the wash tank every hour.
