Our hermetic circuit solvent cleaning systems are able to carry out the washing and drying treatment completely under vacuum. We use hydrocarbon solvents (isoparaffins) class AIII, which have a degreasing power, lower than the chlorinated solvents (i.e. perchloroethylene), But also have on their side the lowest environmental impact due to the non-belonging to any categories regulated by the VOC regulation on emissions they can face countless possibilities. A major example of employ bearings assembly, is the cleaning in finale stage of bearings, the application of this type of solvent is then compulsory, considering the necessary slight residual greasiness left by the solvent itself on the parts.
The construction with high thickness AISI 304 stainless steel (DIN AISI 1.403) (not like the off-line of laundry machines) allows us to reach high vacuum rates to avoid stressing the solvent and also allows the pieces to dry very quickly. The whole plant cycle; spray stage, immersion with or without ultrasound, solvent vapors and drying, takes place under vacuum, this guarantees the hermetic seal of the plant. Each washing stage is carried out with a clean solvent, in fact, each system is equipped with a double distiller that guarantees solvent is always ready and clean, even for short cycle times. This turns into a continuous washing process and a high consistent washing quality. Vacuum drying prevents airborne particles from contaminating the cleaned parts inside the process chamber in a hermetically sealed environment, therefore extremely clean, since the chamber is also “washed” with each work cycle. The operator will not come into contact with the solvent even during
