Disinfection in the elevator - surfaces and air
autonomous and automatic real-time hygiene during operation
The installation of the UVPANEL in elevators will be carried out by the elevator companies. The UVPANEL will be delivered in mid-2021.
The UVPANEL can be installed in almost any elevators. The installation takes place on the cabin ceiling.
Thanks to various sensors with which the UVPANEL is equipped, people as well as animals are detected in the effective range.
After the elevator has been used and is free of people, disinfection by means of UV-C light takes place automatically and autonomously.
As soon as persons or animals approach the effective area, disinfection in the elevator is stopped directly. The safety of the users is guaranteed at all times.
Disinfection is free of chemicals and only the amount of energy required is used.
Each disinfection process is logged and can be retrieved via the Bluetooth interface.
Hygiene in real time and during operation
Most hygiene measures and processes follow a static pattern and a fixed interval. In the graphic, this can be seen in the gray lines.
This is decoupled from the actual use of rooms. This sometimes results in high germ loads on surfaces.
With the UVPANEL, use-oriented hygiene is implemented in publicly accessible areas and without interrupting ongoing operations. This can be seen from the magenta lines in the graphic.
By initializing the disinfection process at the next possible moment after the use of a room, and as soon as no person is in the effective area, germ contamination on the surfaces is reduced promptly and reliably.
How it works
Ultraviolet (UV) radiation, which spans the wavelength range from 100 nanometers (nm) to 400 nm, is the most energetic portion of optical radiation. UV light is classified by wavelength (measured in nanometers (nm)):
– UV-A: 400-320 nm
– UV-B: 320-280 nm
– UV-C: 280-100 nm
The UV-C radiation of the sun is filtered out by the earth’s atmosphere, all UV-C radiation occurring on earth comes from artificial sources.
UV disinfection is most effective at wavelengths from 200 nm to 300 nm. UV-C rays have a strong virucidal and bactericidal effect. It is absorbed by DNA, destroys its structure and inactivates living cells. Microorganisms such as viruses, bacteria, yeasts and fungi are rendered harmless by the UV radiation within seconds. Spreading is thus no longer possible.
With the correct UV radiation dose, all microorganisms such as viruses and bacteria are rendered harmless. The dose is calculated from the power of the UV-C source and the time of irradiation. Each virus or bacterium is deactivated or killed at an individual radiation dose. Since the radiation energy remains constant, only the duration of irradiation is different for each virus or bacterium.
Yes, because the UV rays do not differentiate between different types of microorganisms. UV disinfection depends on the dose of radiation, but also on the size of the organism – the virus, SARS CoV-2, which triggers Covid 19, is small and can be rendered harmless faster than a bacterium.
Furthermore, there is, for example, a study from KOREA University, which has researched exactly this.
Excessive irradiation with UV-C light can cause irritation of the skin (sunburn) and eyes in humans.
However, the systems developed by UVENTIONS prevent people from being injured by the rays during the disinfection process, thus eliminating any health risk for humans and animals.
The UVPANEL will be available on the market in mid-2021.
In principle, the UVPANEL can be installed in any elevator, provided that the cabin ceiling allows it to be mounted. The power supply is routed from the car roof into the car. Integration into the elevator control system is not necessary.
The UVPANEL disinfects indoor areas with the help of UV-C light and renders almost all infectious agents on surfaces and in the air harmless. It can be used in public areas, everywhere where people literally “go hand in hand”.
The USE CASES are versatile, whether in offices, in care facilities, at the airports or sanitary facilities – click here to learn more.
The UVPANEL is equipped with various sensors to ensure that the disinfection process only starts when no persons or animals are present. Should a person approach the effective area, the UVPANEL stops the beams in a fraction of a second. Motionless persons, for example, are also detected so that the UVPANEL does not start disinfecting when there are sleeping persons in the room.
Yes, the UVPANEL requires a power supply, as not enough energy can be used for disinfection through battery operation. We plan with a power supply of 240 VAC, 50 Hz.
Yes, the UVPANEL has a corresponding CE certification.
The mode of action of UCV disinfection was established over a century ago. Therefore, UVC light has long been a common method of disinfecting water, air and surfaces – a method used daily in hospitals, laboratories and factories. The UV rays act on DNA and kill bacteria, viruses and fungi. It is used, for example, to disinfect medical instruments. What is special is that UVC light is also used in the disinfection of drinking water; because now some germs are resistant to chemical disinfectants.
Disinfection with UV light takes place without the use of chemical products and is therefore much more environmentally friendly.
Also, a disinfection process with UV light does not leave any odors, since (as previously described) no chemical agents are used. On the contrary, by inactivating bacteria (which are responsible for the development of odors), the cause of unpleasant odors is eliminated.
Furthermore, it should be noted that in the case of spray or wipe disinfection, the entire surface must be wetted and the exposure time must be observed. User errors can already occur here.
