The story of UVC began nearly 150 years ago.
- 1877: Scientists Downes and Blunt discover sunlight can disable microorganisms.
- Early 1900s: UVC identified as the most effective part of the ultraviolet spectrum.
- 1910s–1920s: UVC lamps developed for water treatment and air purification.
- Today: Modern devices like Tru-D® combine proven science with advanced engineering, sensors, and safety systems.
What began as a scientific curiosity is now a cornerstone of innovative technology used worldwide.
