Cleaning and Drying Equipment "Water Cleaning and Drying System for Lenses and Glass Substrates"
A new standard for HFE drying that uses differences in specific gravity to make "water" float. Determining quality with "three zeros"—that's our job.
This system achieves "zero water stains," "zero drying unevenness," and "zero fire risk," which were challenges with conventional IPA drying and hot air drying. Our proprietary moisture removal device constantly manages trace amounts of moisture in the HFE solvent, stabilizing drying quality. Most of the water adhering to the glass substrate and brought into the HFE water removal and drying system is discharged outside the device by specific gravity separation. Even trace amounts of moisture dissolved in the HFE solvent are reliably removed by the moisture removal device. The HFE solvent water removal and drying system quickly separates water adhering to glass and metal products after cleaning using specific gravity differences and ultrasonic action, completely preventing water stains. It enables safe, energy-efficient, and mass-production compatible precision drying processes for glass, lenses, metal parts, and other products. 【Features】 ○ Avoids fire and safety risks by not using IPA ○ Significantly reduces energy consumption required for drying and suppresses CO₂ emissions ○ Supports mass production lines by improving cleaning speed ○ Reliably removes trace amounts of moisture contained in the HFE solvent ○ Maintains "zero" water stains with a "moisture removal device (optional)" that constantly removes trace amounts of moisture For more details, please contact us or download the catalog.

basic information
[Mechanism of Dehydration and Drying Using HFE Solvent] 1. The workpiece, still wet after cleaning, is immersed in the HFE solvent tank. 2. The water is quickly separated due to the action of ultrasonic waves and the difference in specific gravity between the water and the solvent. 3. The separated water is automatically discharged outside the device via a water separation tank. 4. The workpiece is vapor-cleaned (final cleaning) in the HFE vapor layer and then moved to the drying layer. 5. Complete drying is achieved in the final drying layer. ●For more details, please contact us or download the catalog.

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.
