Knowledge gained from numerous delivery and testing achievements
With a proven track record of delivering to customers in a wide range of industries and a track record of testing in our in-house laboratory facilities, we are able to propose the optimal ozone solution for any problem our customers may have.
History of Precision' Ozone Business
We launched our ozone business in the 1970s, initially focusing on public sector applications such as sewage treatment facilities. In the 1980s, we quickly developed ozone generators for various fields, including high-concentration ozone generators for the semiconductor industry and ozone generators for pool purification.

We established the Water Engineering Center in 1996 and have conducted numerous water treatment tests using ozone.
We can conduct tests using actual water.
We can provide optimal proposals based on the knowledge we have gained from conducting numerous tests, from planning test flows to scaling up to actual equipment after testing.
The test can be performed using ozone alone or AOP (Advanced Oxidation Treatment).
We also have testing equipment for on-site testing. We have ozone generating machines with 10g and 27g capacities, and as these are models with built-in PSA (oxygen concentrators) and compressors, ozone generation is possible as long as the customer provides a power source.
(Ozone piping etc. will also be required separately. Please contact us for details.)
