Customer challenge

The solution

Normal life has changed due to preventive
measures we have to take to protect
ourselves from the present health crisis
caused by Corona virus. Washing our hands
frequently, keeping 1.5 meters distance fromeach other, avoiding direct contact are justsome of the examples. The present healthcrisis caused by Corona virus affects activities
in high-frequent rooms. Special concern isregarding the air that we breath indoors. Thatis the main reason why the managing boardof Mašinoprojekt Kopring a.d. has decided toapply Philips UV-C Upper Air luminaires intheir conference room.

As the conference room is considered to be
one of the rooms with the highest frequency,
installing Philips UV-C Upper Air disinfection
luminaires represents an ideal solution which
provides additional safety and protection
against pathogens. Philips UV-C Upper Air
svetiljka the air that flows through the upperareas of the room thanks to naturalconvection, or air circulation. Thisalso ensures that the disinfected air flows
back to the lower part of the room andmixes with the air. The beam of UV-C rays
is controlled by specific reflectors and thelouvre design. This allows quiet disinfectionof air while daily activities can continue safely.
To date, no known pathogen is resistant toUV-C1. Philips has 35 years of experiencein UV-C lighting and strong applicationexpertise.

UV-C rays are distributed at the height of the luminaire and above.
The beam of UV-C rays is controlled by specific reflectors and the louvre design.
This allows for the disinfection of the air in a room, while day-to-daybusinessactivities can continue underneath the area where the device is active. Philips PL-S
TUV lamp included: 4x9 W.

Inactivates pathogens
Philips UV-C disinfection upper air luminaires inactivate up to 83.6% of SARSCoV-2 virus in air after 2 minutes. After 10 minutes of exposure in the chamber
there was a 99.99% reduction of collectable active pathogen in the air. The live
SARS-CoV-2 virus was not detectable at the 20-minute timepoint2. UV-C light has
been shown to effectively inactivate the pathogens tested3.

Safety first
The luminaire emits UV-C rays in upper areas, at a safe distance from thosewalking
below. Therefore, activities can continue while the luminaire is in operation4.

Respects the environment
No ozone emissions during or after use.
