J.TECH Co., Ltd. is a manufacturer of water treatment equipment in water and sewage disinfection. Notably, our main product is a sodium hypochlorite generator (eco-friendly sterilizer and disinfectant generator) equipped with scale-free cell technology with electrolyte circulation and is installed at the site that requires chlorine disinfection. It electrolyzes brine to produce a low-concentration salt-free solution and to safely and conveniently sterilize tap water. It was selected as an “R&D Outstanding Performance Company” by the Ministry of SMEs and Startups in 2020.


We currently develop an eco-friendly sewage treatment system that can prevent secondary environmental pollution caused by residual chlorine by developing plasma water treatment technology, and are leaping forward as a leading company in the water industry through new technologies.
