Handheld UVC Disinfection Performance

 

 

 

UV Disinfection Systems

Featuring both Mobile & Handheld models, the UV-C High Power Ultraviolet Disinfection System is designed to easily inactivate all microorganisms. These systems are highly effective against dangerous viruses including COVID-19, Salmonella, E-Coli, Polio, Strep, and many other microorganisms. This process is 100% chemical-free leaving behind no by-products making it a great solution for disinfecting large commercial spaces.

Can UVC inactivate COVID-19?

  • COVID-19 is the respiratory disease caused by the SARS-CoV-2 virus that has caused outbreaks worldwide. The SARS-CoV-2 is a new variant in the betacoronavirus family (Fisher 2020).
  • COVID-19 is a small, single-stranded RNA virus that makes it much easier to inactivate in comparison to mold or any sporicidal pathogen. 

    “The inactivation rates of the small RNA viruses, poliovirus 1, and coxsackievirus B4, by low pressure UV were very rapid and reached approximately 4 log and greater than 5 log, respectively, within a UV dose of 30 mJ/cm2.” – Environmental Protection Agency

  • UVC probably destroys the novel coronavirus, but we need to learn more.
  • UVC  has been found to destroy viruses and other microbes on surfaces.
  • The U.S. government and the UV technology industry are working to define standards for UV disinfection technologies in healthcare settings.
  • Most UV sanitizers have not been tested against the novel coronavirus, SARS-CoV-2, but UVC  has been shown to destroy related coronaviruses, including the one that causes the disease MERS.

How Does UVC Work?

When UVC wavelengths enter a cell, it disables the cell by damaging critical nucleic acids and proteins by forming duplicate bonds called dimers rendering the organism inactive or unable to reproduceThe germicidal effects of UVC wavelengths neutralize a wide variety of pathogens. UVC light enters the cell's nucleus, causing irreversible damage to RNA (Viruses) and DNA (Bacteria). 

This UVC disinfection system is effective with proper dosages on bacteria, viruses, fungi, and protozoa on a variety of surfaces, materials, and objects.  

"UV light between 200-280 nm inactivates at least 2 other coronaviruses that are near relative of COVID-19 (SARS-COV-1 and MERS-COV)"

Applications of UV Light

UVC: Eliminates Mold, viruses, and bacteria in the air & surfaces, disinfects drinking water & treatment of sewage.

UVB: Phototherapy, skin treatment, Vitamin D production, and cannabis THC potency.

UVA: Tanning, treatment of skin diseases, indoor gardening, eradicating bugs, improving air quality, and object identification.

UVC Disinfection

Viruses are much easier to kill than bacteria and mold, as viruses are much smaller in size. Increasing the dosage time increases disinfection effectiveness.

See our UV Dosage for a Given Log Reduction document for a list of common pathogens and the required UV dosages.

UVC Disinfection Dosages

The average bacterium will be deactivated in 17 seconds at a distance of 4 in. with our Handheld system. Disinfection effectiveness increases as the processing time increases, however, effectiveness decreases as the distance from the surface to the lamp increases.

Using Dosimeter Cards we can accurately provide disinfection assurance data for any application-space. Other disinfection variables include: The Pathogen, Square Footage of Disinfection Space, Distance of the Lamp from the Surface, and mJ/cm2

We have created a log for your business to record UV-C treatment times.  It can be customized with your logo.  Download the word document here
