MODIFIED ALCOHOL
ITF’s hermetic circuit solvent cleaning systems can finish the washing and drying processes fully under vacuum. They employ alcohol derivative solvents (modified alcohols or better alchopropanol), which have a degreasing capacity similar to chlorinated solvents and are especially used when a strong degreasing phase is required, clearly superior to hydrocarbons (similar in chemical-physical characteristics but different in their management). They have minimal toxicity and eco-toxicity, and they evaporate entirely without leaving residues on the pieces. They are non-corrosive and, unlike chlorinated solvents, can remove water from metal surfaces. They also do not require the use of stabilizers.
Our Standard
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. Our construction method is different from our competition in the market because the construction of our work chamber is integrated in the system body (we do not have many tanks and pipes that dissipate heat and in the long run do not guarantee sealing under vacuum conditions). Through our integrated module construction, we use the solvent vapors generated by the distiller to equip the chamber with thermal energy, so we have a continuous distillation and never interrupted, thus reducing the thermal energy used to restore the necessary distillation regime, reducing consumption electrical and always obtaining a greater quantity of vapors for the final phase of the process and for their condensation. The relocation at the customer’s plant after the pre-acceptance tests in our factory, ensure that what is found in pre-testing is actually what is expected and required in the final testing phase and put into production. The system is independent and extremely flexible, since the installation is of the “plug-in” type, being equipped with independent heating and cooling systems therefore does not require further connections for heat sources or cooling water.
What We Remove
Total elimination of all sorts of pollutants from treated (metallic and non-metallic) parts, whether simple or morphologically complex, with blind and threaded holes, tapped or rolled, flat or with recesses or cavities, all the way up to the microstructure of sintered material components. Oil (whole and emulsions), lapping oils, polishing pastes, waxes, shavings, powders and particulates, greases, footprints, earth and foundry sands, salts, and other pollutants and impurities are all removed.
