How can UV light protect against pathogens?

In a world that is more focussed on hygiene than ever, we wanted to explore UV and it's ability to protect against bacteria and viruses.

There are three main types of UV rays; UVA, UVB & UVC. The length of UVC waves are the shortest and therefore the ones with the highest energy, this means they are capable of killing bacteria and viruses, also called pathogens.

UVC is highly effective at killing pathogens. It does this by destroying the molecular bonds that hold their DNA together. This also included 'superbugs' which have developed a stronger resistance to traditional antibiotics.

Killing bacteria and viruses with UV lights has the benefit of being effective even against germs which are resistant to drugs and does it without needing any toxic chemicals.

​MagnaCool 2800 Supreme - UV System

Here at Magnacool, we offer the option of adding a fully functional UV system within our Magnacooler, killing 99.99% of E-coli micro-organisms. The UV disinfection system is installed safely within the Magnacooler. The system provides disinfection of airflow by using germicidal ultraviolet radiation at wavelength of 254nm which disables biological contaminants such as viruses, bacteria and moulds.

As we transition back into something that resembles normality, we will all need to do what we can to protect ourselves. As yet, UV hasn't been tested against COVID-19 and therefore we can not comment of it's effectiveness against it, however using UV to kill bacteria and viruses has many benefits regardless. We are looking forward to the government's test results in relation to UV and COVID-19 and will update you accordingly.
