Stanley Electronic Components

Sterilization UV light source for water, air, surface sterilization

Under Development

UV-CCL water sterilization reactor


A unit capable of full sterilization despite its small size, contributing to safety, security and comfortable living

Compared to conventional hot cathode UV lamps, it takes less space with the same sterilization capability.
We will recommend the most suitable usage method according to the usage conditions.


Water purifiers, water servers, warm water washing toilet seats, etc.
