Pulsed light disinfection robot has become a hot cake after the continuous strikes of Covid-19. Now almost every hospital and commercial place is installing these robots to disinfect their places. Since there are a lot of advantages these robots provide, we shall discuss some fundamental aspects of uvc technology.
What is UV radiation?
Ultraviolet is called electromagnetic radiation, which occupies the spectral range between the visible and X-rays. UV rays are invisible to the human eye. The wavelengths of UV radiation lie in the range from 100 to 400 nm. The term comes from lat. ultra – above, beyond and purple (violet).
Low pressure UV robots emit UV light at a wavelength of 254 nm, which is close to the peak sensitivity of microbial DNA and RNA at 265 nm.
Types of UV Robot
For domestic use, a UV robot is most often chosen for disinfection purposes. It effectively destroys parasites, insects, viruses and bacteria. Depending on the specifics of the design, the ultraviolet robot works automatically to disinfect anu open or close space.
Principal of operation of pulsed light disinfection robot
The principle of operation of such devices is extremely simple. They have cloud management system. An open UV room disinfection robot effectively destroys bacteria, disinfected spaces of hospitals. During the treatment of the room, UV waves activate the process of spreading ozone. Thanks to this, bacteria are destroyed quickly and as efficiently as possible.
Ultraviolet radiation for disinfection of premises prevents the spread of pathogenic microorganisms, while maintaining a safe microflora.
The advantages of pulsed light disinfection robot in the treatment of clinics are clear. It is an ideal and indispensable helper for the hospitals destroying germs, bacteria and pathogenic viruses.
How to choose the right pulsed light disinfection robot?
In the last few years, the epidemiological situation in the world leaves much to be desired. People have to deal with a large number of viruses, bacteria, pathogens. In such conditions, the question of how to choose a pulsed light disinfection robot for the clinic spaces becomes extremely relevant.
If you do not know which disinfection robot to choose, be guided by the following criteria:
Power: An ultraviolet disinfection robot for disinfecting rooms with an area of 200nm-315nm easily carries day to day disinfection procedures. For the treatment of rooms with an area of \u200b\u200bmore than 40 m², devices with a power of 36 W are used.
Selection: Thinking about how to choose pulsed light disinfection robot, decide on the task that it will perform.
Irradiator type: Ultraviolet disinfection of premises can be carried out by installations of open and closed types.
Attachment type: Depending on the design features, UV robots can be portable and stationary. In the first case, they easily move from one room to another, disinfecting individual niches and areas. Mobile structures are equipped with wheels, which facilitates their movement.
Manufacturer of pulsed light disinfection robot
If it is important for you how to choose the right UV robot, you should pay attention to the manufacturer unit. The quality, functionality and cost of a UV robot depend on this.
Thus, you should thoroughly approach the issue of how to choose a UV robot. Multifunctional models can be equipped with filters that not only disinfect the room, but also trap dust.
The technology of ultraviolet disinfection is based on the bactericidal effect of UV radiation.
UV irradiation is a physical disinfection method based on photochemical reactions that lead to irreversible damage to DNA and RNA. As a result, the microorganism loses its ability to reproduce – it is inactivated.
UV disinfection technology can be used in numerous fields such as hospitals, bus terminal, all commercial places, and areas where there is a huge crowd of people on daily basis.
Best UV Range of Disinfection Robots
The UV-C range is referred to as bactericidal due to its high decontamination efficacy against a wide range of microorganisms.
Radiation in the wavelength range from 200 to 315 nm has the greatest bactericidal effect, and the maximum bactericidal sensitivity of microorganisms occurs at a wavelength of 265 nm.
UV Intensity × Time
UV intensity is determined by the power, the number of UV lamps and the transmittance of the medium.
How does UV kill viruses?
How does it all work? The fact is that the virus does not have a protective cell wall or membrane.
What is a virus?
Therefore, short UV waves quietly penetrate into its insides and act directly on DNA and RNA, destroying them. But it is the doubling of the nucleic acid molecule that is responsible for the reproduction of the microorganism.

Even if UV rays do not kill the infection (low intensity or duration of exposure), they still stop its reproduction. And if you can’t reproduce, then you no longer pose such a danger to other healthy cells.
But most importantly, none of the viruses can adapt to such exposure.
What does it mean? There are several types of disinfection of premises, including chemical.
Chemical treatment of premises
So, during chemical treatment, there is some probability that certain types of viruses and microorganisms can subsequently change and develop resistance to certain solutions or their concentrations.
But there is no UV protection. No matter how the contagion mutates, direct exposure to harsh ultraviolet light on its nucleic acids will eventually cause it to die. They are afraid of such radiation, like vampires of the sun. No matter how new and unexplored the virus is (Covid-19, SARS, etc.), it still has DNA, RNA, which means that short-wave UV will penetrate into its insides and destroy it from there.
Summary
According to studies, for an irradiation efficiency of 99%, a dose of about 1000 μWsec/cm2 is required. This intensity will kill all viruses containing RNA, single strand DNA (coronavirus), and more likely in 90% of RNA, double strand DNA.
