"Don't throw away expensive HFE/HFO solvents – reuse them!" Simply put the waste liquid into the system and recover over 99% of it in a condition equivalent to new!
Waste liquids containing used HFE/HFO/chlorinated solvents still contain recoverable solvents. Okawa Kogyo's solvent recovery system "OK-GREEN1" can stably recover high-quality recycled solvent simply by introducing waste liquid containing HFE/HFO/chlorinated solvents. It reliably recovers solvents from waste liquid in a condition equivalent to new solvent. The waste liquid after recovery is not difficult-to-treat fluorinated waste liquid, but can be treated as ordinary waste oil or industrial waste. It reduces waste liquid treatment costs while realizing the reuse of expensive solvents. Continuous operation is also possible by connecting it to a cleaning machine, minimizing equipment downtime. For companies that use large quantities of HFE/HFO/chlorinated solvents, we recommend adopting OK-GREEN1 from both environmental and cost perspectives. Furthermore, by integrating it into a cleaning system, it is now possible to continuously reuse the solvent while removing only the "dirt" during cleaning. [Features] ○ Recovers recycled liquid simply by introducing used waste liquid ○ Solvent recovery rate is 100% ○ Can be connected to a cleaning machine ○ Reduces industrial waste disposal costs ○ Recovered solvent can be reused with confidence

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.
