Finishing cleaning process: Degreasing cleaning device (co-solvent method)
Co-solvent degreasing cleaning device
In lens, prism, and precision parts cleaning, the cleaning solvent is always regenerated and reused, allowing for high cleaning precision. Moreover, the solvent consumption is significantly reduced.
Co-solvent method for cleaning and drying using two types of cleaning solvents. This cleaning system uses hydrocarbon-based cleaning solvents (HC solvents) for cleaning and HFE/HFC solvents (rinse solvents) for rinsing and drying. The dirt dissolved in the HC solvent is distilled and regenerated using an HC vacuum distillation machine and is discharged outside the equipment. The HC solvent brought into the rinse solvent undergoes a solvent separation process, and the HC solvent and rinse solvent are returned to their respective cleaning tanks for reuse. 【Features】 ○ Economical The cleaning solvent is reused due to the HC/HFE distillation unit and HC/HFE separation unit (significantly reduced solvent consumption). The expected solvent usage is calculated and presented during estimation. ○ Safe Solvents of safe Class 4 and Class 3 petroleum products with high flash points can be used. Non-cleaned items do not exceed the boiling point temperature of the fluorinated cleaning solvent. ○ Cleaning Precision After cleaning with hydrocarbon-based cleaning solvents with a surface tension of about 25 nN/m, rinsing and drying are performed with fluorinated cleaning solvents with a surface tension of about 13.6 nN/m. High-precision cleaning results can be expected. ● For other functions and details, please download the catalog.

Company information
The three "R" themes that Okawa Kousan Co., Ltd. places great importance on are as follows: ◆ R1 - Recycling (Low Running Costs) We recover all solvents used in the purification process and return them to the cleaning system. ◆ R2 - Repair (Stable Production) We always strive for prompt maintenance and inspections. Regular maintenance is recommended to prevent downtime in the manufacturing process. ◆ R3 - Reduction (Promotion of Eco-friendliness) We reduce the amount of energy and solvent consumption associated with the cleaning equipment.
