OverviewThe Excelitas LED-based Kepri UVC Upper-Air Disinfection System provides continuous, real-time disinfection of upper-room air while rooms remain occupied. Its compact, low-profile housing and dust-free optical chamber enable long service intervals without ozone emissions, making Kepri suitable for healthcare, clinical and other occupied indoor environments.
The Upper-Air ConceptKepri creates a controlled UVC irradiation zone in the upper portion of a room. As air circulates, pathogens passing through this zone receive germicidal UVC exposure, damaging DNA/RNA to prevent replication and transmission. Continuous upper-air UVC disinfection can achieve effective airborne pathogen reduction with lower power than traditional lamp-based systems when properly installed and coupled with room air mixing.
Occupant-Safe OperationKepri integrates a three-tier sensor monitoring system to maintain safe operation in occupied spaces:
- Tilt sensor to prevent harmful downward UVC emission if the unit is displaced.
- Presence sensor that disables UVC emission when an object or person enters the central emission field.
- Motion-activated occupancy sensor with a three-position selectable switch to set user operating preferences.
Effective Pathogen EliminationIndependent laboratory testing (Intertek) demonstrated a 99.9% reduction of tested bacteriophage (Phi X174) in 20 minutes under test conditions. Equivalent air changes per hour (ACH) were extrapolated from the test; actual disinfection performance depends on room air mixing, ceiling height and pathogen characteristics.
