With the current global Coronavirus Pandemic (COVID-19), the virus has been shown to be active on surfaces and potentially air for between 0 to 12 days. Recent International studies have shown that the average is up to 2 days active on surfaces (Kampf, G, 2020). UVC or Germicidal Light (254nm) is able to inactivate viruses with 99% reduction of typical viruses and bacteria in a 1-minute timeframe and on spores like C. difficile in 5 minutes.
UV Solutionz High Energy Germicidal UVC Germicidal Technology is used for many applications including killing airborne and surface pathogens including Coronavirus (COVID-19) (Viruses, Bacteria and Moulds) that live, replicate and move through building via a building forced air HVAC system.
Air borne pathogens are often introduced to a building via incoming occupants, fresh air intakes and often on construction materials. An HVAC system cooling coil which chills the air is the perfect environment for these microbial contaminants to live and thrive in that it’s a cold, damp and dark place. This allows a prime location for Viruses, Bacteria and Mould to reproduce and then produce air borne pathogens which can affect your building occupant’s health and productivity. This machinery receives very little, if any care in the way of maintenance/cleaning as it’s generally are hidden away from view, often difficult to access and the microbial contaminates are invisible to the eye unless they prolificate to the point of being macroscopic.
UV Solutionz High Energy Germicidal UVC Technology when installed in your HVAC system to our specifications has the power to destroy airborne and surface pathogens quickly and effectively, preventing them from growing and multiplying while also sterilising the air. UVC Germicidal Technology also improves your Indoor Air Quality (IAQ) by reducing Volatile Organic Compounds (VOCs) from such things as paints, carpets, renovations, outside introduced smells.
Forced Air applications include:
How Does UV Work?
Ultraviolet light exists within the spectrum of light between 10 and 400 nm. The germicidal range of UV is within the 100-280nm wavelengths, known as UV-C, with the peak wavelength for germicidal activity being 265 nm. This range of UV light is absorbed by the DNA and RNA of microorganisms, which causes changes in the DNA and RNA structure, rendering the microorganisms incapable of replicating. A cell that can’t reproduce is considered dead; since it is unable to multiply to infectious numbers within a host. This is why UV disinfection is sometimes called ultraviolet germicidal irradiation (UVGI).
Our UV systems use low-pressure, mercury-arc germicidal lamps which are designed to produce the highest amounts of UV radiation – where 90% of energy is typically generated at 254nm. This radiation is very close to the peak of the germicidal effectiveness curve of 265nm, the most lethal wavelength to microorganisms.
