Our FUV 222nm excimer light disinfection systems kill bacteria and viruses in occupied spaces.

Far UVC 222nm excilamp is the safe and right solution for The Most Effective Sanitation

Scientists have known for decades that broad-spectrum germicidal UV light, which has wavelengths between 200 and 400 nanometers (nm), is highly effective at killing bacteria and viruses by destroying the molecular bonds that hold their DNA together. This conventional UV 254nm light is routinely used to decontaminate surgical equipment. Unfortunately, conventional germicidal UV 254nm light is also a human health hazard and can lead to skin cancer and cataracts, which prevents its use in public spaces. We add that previously 254nm mercury lamps were used to fight viruses and bacteria, but it is undesirable to use them for medical or biological applications because of the risk of depressurization of contamination of the environment with mercury. The term FUV KrCl 222nm "excilamps" is used for ultraviolet lamps that emit ultraviolet 222nm light by the decay of excimer and exciplex molecules. The first lamps of this type were developed in 1982 at the State Optical Institute, SI Vavilov in Leningrad now Russia. The study of the effect of radiation from 222nm KrCl and 207nm BrCl excimer lamps on microorganisms and chemical particles began precisely at Tomsk State University - at the Department of Cytology and Genetics - at the beginning of 2000. Thanks to these studies, it was found that, in terms of their technical parameters, excilamps are a very effective system for carrying out ultraviolet inactivation of viruses, bacteria and pathogens. The research was supervised by Dr. Eduard Sosnin from the Faculty of Physics of Tomsk State University in Russia. David Brenner directs the Center for Radiological Research at Columbia University, Irving Medical Center in New York City. Over the past eleven years, Dr. Brenner and his team have been developing the use of FUV-excimer radiation to neutralize bacteria, bacterial spores, moulds, yeasts, and viruses—including SARS-CoV-2. His research proved that FUV KrCl excimer technology is safe for humans and can be deploy in occupied spaces. Another study published in September 2020 in the American Journal of Infection Control by researchers at Hiroshima University, entitled "Effectiveness of 222-nm ultraviolet light on disinfecting SARS-CoV-2 surface contamination", found that 222nm UV excilamps eliminate 99.7% of surface contamination by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19.

Future of Sanitation

Far UV 222nm Vendi222 excilamp is the future safe for humans solution for all occupied and unoccupied spaces to eliminate COVID-19, Nipah, any viruses, bacteria and pathogens. Our Far UV excilamps produce 100% power sterilization output in less than a second. Our excilamps are green-energy, mercury-free devices. They last up to 10000 hrs.

Powerful Features

Far UV radiation Vendi222 excilamps inactivate viruses, bacteria or pathogens with no harm to exposed human or animal skin and eyes. This is because, due to its strong absorbance in biological materials, the 222nm FUV-radiation cannot penetrate even the outer (non-living) layers of human skin or eye. But because viruses and bacteria are much smaller than human cells, the 222nm FUV-radiation can reach their DNA and kill them.

FUV-222nm excilamp

Kills CoronVirus, bacteria, and viruses. It is as more effective as conventional germicidal UVC light (254 nm) and is safe for humans and animals, scientific studies show.

1. Application of excilamp

Sterilization of any environment with a high likelihood of airborne-based virus, bacteria or pathogens transmission, including COVID-19, tuberculosis, small pox, severe acute respiratory syndrome (SARS) and pandemic influenza, which collectively affects one billion people annually.

2. Application of excilamp

Reduction of a surgical site infection, which still represent a major complication of surgical procedures . Current evidence suggests that the majority of SSI result from bacteria alighting directly onto the surgical wound from the air.

3. Application of excilamp

UV-radiation excilamp efficiently and safely inactivate any mutation of airborne coronaviruses COVID-19. In all occupied and unoccupied spaces like underground mines, military facilities, kindergarden or schools.

4. Application of excilamp

Cleaning of laboratories and meat packing facilities. Sterilization of greenhouses. Cold chain disinfection before exporting frozen food now required by many countries including China

5. Application of excilamp

Excilamps provide remediation of polluted air streams. They also provide photochemical detoxification and purification of water decontaminated with organic substrates and with bacteria.

6. Application of excilamp

Sterilization of airports, restaurants, sports facilities, airplanes, trains, buses, horse stables, animal farms, cars, cruise ships, commercial offices, factories, schools and etc.

The Far UV KrCl excilamp (222 nm) was tested for its action against different bacterial species. We have demonstrated that 99Æ9% bacterial disinfection by the FUV KrCl excilamp occurred even when significant shielding effect was observed at high initial populations of 106–107 CFU ml).

A Columbia University study showed that 222nm FUV-radiation’s narrow band of wavelengths is short enough to prevent it from damaging living human cells, but it can still penetrate and kill small viruses and bacteria on surfaces and in the air.

Here we extended our previous studies to 222nm light and tested the hypothesis that there exists a narrow wavelength window in the FUV-radiation region, from around 200–222 nm, which is significantly harmful to bacteria, but without damaging human cells in tissues.
