LED systems for precise control and energy-efficiency
Polytec energy-efficient UVC LED systems ensure safe and effective disinfection without producing harmful ozone gas. These LED solutions include real-time room air disinfection, and fully customized UVC LED disinfection systems designed to meet specific customer needs.
Kepri – UVC LED upper-air disinfection system
Continuous UVC Disinfection of Upper-Room Air
The Excelitas Kepri™ UVC Upper-Air Disinfection System is designed for continuous disinfection of upper-level room air. The compact, wall-mounted system uses UVC LEDs with a typical wavelength of 270 nm to create a defined disinfection zone above the occupied area. Natural and forced air movement carries airborne microorganisms through this zone where they are exposed to UVC radiation.
A three-tier sensor system supports safe operation even in occupied rooms. Tilt, presence and motion sensors monitor operating conditions and can deactivate UVC emission when required. The system operates without mercury and does not generate ozone.
Key features
- Continuous upper-air disinfection
- Mercury-free and ozone-free
- for operation in occupied rooms
- Low-noise operation
- Three-tier sensor safety concept
- Integrated tilt sensor
- Presence sensor with automatic UVC shut-off
- Motion-activated operating modes
- Dust-free optical chamber for reduced maintenance
- Compact and easy to install
- Meets UL 8802 Issue 4
Proven efficacy
In independent testing by Intertek, the Kepri system was evaluated using Phi X174 bacteriophage. The test demonstrated a 99.9% reduction after 20 minutes.
Typical Applications
- Hospitals and waiting rooms
- Medical and dental offices
- Long-term care facilities
- Childcare centers
- Schools and lecture halls
- Offices and conference rooms
- Restaurants and retail spaces
- Airports and train stations
