Our hermetic circuit solvent washing systems are able to carry out the washing and drying treatment completely under vacuum. Chlorinated solvent washing systems have a completely hermetic circuit operation and work with super-stabilized perchlorethylene which has a high solvent power and very stable. Perchlorethylene is compatible with most metals, particularly those that are easily oxidized such as aluminum, stainless steel, magnesium, zinc and alloys such as brass, etc.
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 maintenance. All the operations of loading and unloading of the solvent, of drainage take place automatically and the cleaning of the filters takes place with the preventive deodorization.
