Core and Proprietary Technologies
Our core and proprietary technologies for filters
Liquid filtration is generally based on technology of separating solids from liquids. We have been refining this technology to such extent that enables us to remove all unwanted particles and contaminants, which are larger in size, while allowing the smaller pigments and desired components to pass through the filter. This is called classification that constitutes our core technology. Our classification technology has been adopted and used by our customers worldwide as an essential technology for the production of indispensable everyday products.
Note: In May 2006, ROKI TECHNO was selected by the Ministry of Economy, Trade, and Industry of Japan as one of the most outstanding 300 SME’s due to this technology innovation.
Our core and proprietary technologies for ozone systems
In semiconductor manufacturing process, the presence of traces of metal ions in cleaning solutions can cause problems and defects.
ROKI TECHNO’s innovative design of placing double quartz tube system in the discharge unit of our ozone generators enables us to produce a cleaner ozone gas without these metallic contaminants. This pioneering technology has been acknowledged and recognized by the semiconductor industry.
