UV Light Source for Ozone Generation Equipped with Clean172™
By using an excimer lamp with a peak wavelength of 172 nm as the light source, ozone production equivalent to discharge ozone generation is possible without emission of nitrogen oxides (NOx). The 172 nm ultraviolet light and reactive oxygen species (e.g., ozone) enable deodorization※1, disinfection※1, TOC reduction, and chemical decomposition※2.
- ※1 It does not work on all bacteria and odors. The sterilizing effect works on bacteria exposed to ultraviolet light.
- ※2 This applies to substances such as: formaldehyde, acetaldehyde, trimethylamine*3, methyl ethyl ketone (MEK), methanol, ethylene oxide (EOG), ammonia*3, nicotine*3, etc.
- ※3 Please note: Because inorganic components are present, substances other than CO₂ and H₂O may be released.
