Vapour degreasing cleaner using solvents
There are many solutions for degreasing workpieces . In the past , use was often made of trichlorethylene , fluorinated hydrocarbons and Isopropyl alcohol ( IPA ).
However , these liquids involve many environmental and safety hazards . Degreasing in water-based systems is a worthy alternative . However , the operational costs of these types of machines are relatively high . Not only heating the liquids for cleaning and rinsing , but also drying with hot air causes a high electricity consumption . For good results it is important that you change the liquids regularly . Costs due to the high water consumption and the processing of the waste water add up quickly . Affordable degreasing in a sustainable and efficient way is possible with modern solvents in a vapor degreaser .
Fast and powerful degreasing with safe means for people and the environment , that is possible with the range of solvent cleaners that Kemet offer . The dimensions vary from handy and mobile ( approx . 622 x 870 x 1050 mm ) to a compact machine ( approx . 2000 x 1000 x 3000 mm ).
Developments in chemistry make thorough cleaning possible . At the same time , ozone depletion and fire hazard are excluded . The low GWP and toxicity make these solvents very easy to use .
Despite the compact footprint of a vapor degreaser , the cleaning process consists of several essential phases to achieve a perfect result . You bring the solvent to the boiling point ( often 40 - 45 ° C ). In a first phase , the solvent vapours condense on the workpiece surface . Much of the contamination flows with the solvent from the workpiece and ends up in the cooking tank . After this pre-cleaning , the part is placed in a second tank . The immersion in the clean solvent and the ultrasonic agitation thoroughly clean the workpiece , even in hard-to-reach places . Then , by reinserting the part into the distilled solvent vapor zone , the vapor purge removes any residual oil or grease residue . Cooling coils above the vapor phase condense the solvent so that it flows back into the machine . The liquid is thus continuously distilled and reused .
Thanks to the low temperature of the entire process , you degrease thermally sensitive workpieces without risk . The drying process is so fast that a capacity of 10 batches per hour is no exception . Thanks to the low surface tension , you can easily clean small bulk goods or workpieces with complex geometries .
