Kepri UVC Upper-Air Disinfection System
The Excelitas LED-based Kepri™ UVC Upper-Air Disinfection System provides real-time disinfection of upper-level room air regardless of room occupancy. With a truly unique design, our Kepri UVC Upper-Air Disinfection System allows for safe and effective room air disinfection without emitting any harmful or environmentally unfriendly ozone gas.
The Upper-Air Concept
As pathogens pass through the active UVC disinfection zone, the UVC light damages the pathogens’ DNA/RNA, preventing its ability to replicate and effectively inactivating its ability to infect and spread. This continuous disinfection offers higher levels of effectiveness when compared to other traditional UV lamp-based air germicidal treatments at lower power.
The compact Kepri UVC Upper Air-Disinfection System is easy to install in a wide variety of spaces. Featuring low noise operation and a dust free optical chamber, this low-profile design minimizes maintenance requirements and ensures maximum UVC emission over its lifetime.
Occupant-Safe Operation
As safety is critical in UVC disinfection, Excelitas sets the industry standard with a three-tiered sensor monitoring system to ensure safe operation, even in fully occupied rooms:
- Tilt Sensor:a safety feature to ensure no harmful UVC energy is emitted into the lower part of the room.
- Presence Sensor:detects anyone in the UVC central emission field (i.e. changing a lightbulb on a ladder) and immediately turns off the UVC emission until the emission field is clear.
- Motion-Activated Occupancy Sensor and Switch:detects movement in the room and allows the user to select their individual operating preference using a three position selectable switch.
Excelitas meets a stringent UL-8802 standard which limits the amount of UVC energy into the lower part of the room, assuring safe operation.
Effective Pathogen Elimination
Excelitas has tested the efficacy of the Upper Air disinfection system against one common virus (Phi X174 bacteriophage). An independent lab, Intertek, found Kepri reduced the bacteria by 99.9% in 20 mins.Click here to view our Efficacy Test Report.
Notes:
1.Equivalent air exchanges per hour (ACH) for a room with a 10ft (3.0m) ceiling.
2.Values are extrapolated from Intertek test data dated Dec 17, 2021- available on our website. Original single point test measured a 99.9% reduction of Coliphage φX174 (typical single stranded virus) in 20 minutes.Equivalent air exchanges for other pathogens will differ.
3.The times given assume perfect air mixing within the space (i.e. mixing factor = 1). Disinfection rates are dependent on air mixing. The following equivalent air exchange (ACH) data should only be used as a best-case guideline.
