UV water sterilization module
-
We are working on the development of UV water sterilization module using UV-LEDs.
-
Instead of using chemicals, UV-C light can inactivate microorganisms such as bacteria, viruses, and fungi. It is possible to minimize the impact on the environment.
-
There is various choices of size and the installation method of the device, which makes it possible to be used in a wide range of situations.
-
The lenses used in the module are molded from our original glass material that transmits UV light.
-
*This developed module is a jointly developed product with ZS Electronics & Automation.
