About UVC desinfection.

CORONAVIRUS CONTROL DISINFECTION OF AIR AND SURFACES UVC RADIATION - COVID 19

MOBILE UNIT

GERMICIDE 2020


This unit makes it possible to disinfect much faster than by disinfecting the room in a classical manner, without wasting time and product and without counter-application. Indeed, as soon as the desinfection session is finished, you can enter the room.

It is sufficient to place this unit in the middle of the room to be disinfected, on a table, a bed or on the floor. Any bacteria or viruses floating in the air and environment are destroyed within minutes. It will be the same for all irradiated surfaces.


The radiation from mercury vapour lamp has a wavelength of 253.7 nm and very easily penetrates the microorganisms and cells and disrupts the structure of their DNA, making it impossible for them to multiply and de-facto prevent them from spreading.


Although our body cells are much larger, making UVC penetration difficult, exposure to this radiation to a person is not recommended despite having very little effect on the DNA of our cells. This radiation is also blocked by the windows on which it is reflected. Another special feature of this beam is that it partially splits the air molecules into ozone, this phenomenon is also the reason that the sunlight gives off very little UVC radiation because it is filtered by the oxygen in the air it passes before it reaches floor.


Ozone is also germicidal and will enter all small fractures and kill the micro organisms. The disinfection cycle takes 15 to 60 minutes, depending on the volume of the room. At the end of the disinfection it is advisable to ventilate to remove the slight ozone odour and the destroyed microorganisms.


When the disinfection cycle has started, the lamps will only warm up after 10 to 15 seconds and then turn on at full power. This gives enough time to leave the room safely.


The appliance is equipped with a remote control with which you can set the duration. 1 "5, 30 or 60 minutes, the lamp has a 360 'range.


To prevent a child or a person from entering the room, the device is equipped with a motion detector that automatically switches off its operation as soon as it detects the presence of a person.


For proper operation, the DERMICIDE 2020 is equipped with the following:


  • A switch with voltage indicator.
  • A remote.
  • A timer.
  • Voltage: 230V 50Hz
  • Power: 36W
  • Colour black
  • Sizes: diameter 155 mm Height: 423 mm

Some more info about UV desifection

UVC germicidal lamps have been used for many years to disinfect air and surfaces in hospitals, nursing homes, laboratories and many other organizations where hygiene and cleanliness are of the utmost importance.

 

UVC 253.7 nm radiation is a proven technology to reduce bacteria, viruses and other harmful microorganisms that pose a risk to human health.

 

UV-C radiation kills or activates microorganisms by destroying nucleic acids and disrupting their DNA, rendering them unable to perform vital cellular functions.

 

UVC lamps are used to reduce and control the spread of Covid-19.

 

The following information has been published by ResearchGate.net regarding the sensitivity of coronavirus to UV rays.

ResearchGate is committed to supporting the researchers and organizations around the world fighting the COVID-19 pandemic

Table 1 above summarizes the results of studies conducted on coronaviruses exposed to UV radiation, with the specific types listed in each case. The D90 value indicates the dose of UV for 90% inactivation.

While there is a wide range of variations in D90 levels, this is typical of laboratory studies on UV sensitivity.

 

The D90 range for coronaviruses is 7 to 241 J / m2, with an average of 67 days / m2, should adequately represent the UV sensitivity of the SARS-CoV-2 virus (COVID-19).

 

Covid-19 is 100 times smaller than a bacteria or 1000 times smaller than a red blood cell. Its small size makes it very volatile and it can float in the air long enough.

Using this exposure data and comparing the energy illumination measurements of UVC 253.57 nm from our lamps and disinfection systems, we can easily calculate the exposure times required to obtain a certain logarithmic reduction based on certain distances from the source. All items, except for the LED lights that light up immediately, have a short preheat time of 3 to 5 minutes to reach full power. The devices are powered by the electricity network.

 

Dynamic Research International offers efficient and safe disinfection units to shops, hospitals, homes, gyms or any other location to quickly disinfect (truck, bus, warehouse, gym). At the same time, they disinfect the air passing through the radiation and, of course, the affected surfaces.

Precautionary measures


✔ UV-C rays can damage the eyes and skin. People, children and animals should not be exposed to UV-C light. You must leave the room when using the UV-C lamp and allow the disinfection time to take place, from 15 minutes to 3 hours, depending on the surface to be treated.


✔ UV-C causes a slight ozone emission (but ozone also degrades viruses and bacteria), so it is advisable to ventilate the room after use.
