COVID FAQs

Frequently asked questions we have received during the 2020 Coronavirus pandemic regarding germicidal ultraviolet (UV-C) disinfection

The emergency of COVID 19 spread has highlighted the need for an innovative approach to disinfection needs, not only in terms of sanitizing environments and surfaces. UV rays have offered positive results in the fight against SARS and MERS, two viruses very similar to the current Coronavirus. The use of UV-C radiation is a safe, efficient and cost-effective solution, avoiding the use of hazardous chemicals.

WHAT ARE THE MAIN ADVANTAGES OF USING GERMICIDAL UV-C LAMPS?

Bacteria, viruses, spores, fungi, moulds and mites are all sensitive to UV-C rays and can be eliminated by them.
Microbes cannot acquire resistance to UV-C rays, which only occurs using chemical disinfectants and antibiotics.
UV rays are eco-friendly. When using normal disinfectants, environmental pollution is inevitable. They also carry severe risks from the direct inhalation of vapours or the ingestion of foods contaminated after coming into direct contact with chemical disinfectants.
Where the use of chemical disinfectants is unavoidable (food/ pharmaceutical/ healthcare industries, etc.), using ultraviolet rays in the disinfection process can reduce the amount needed, which allows for significant cost savings and is better for the environment, while maintaining – and, most of the time, improving – disinfection quality.
UV-C ray devices can be installed in most environments and machinery and can be programmed to maintain the same level of disinfection day and night, ensuring ideal conditions of hygiene without any fluctuation in quality. In contrast, chemical disinfectants are most effective at the time of use.
SPECTRA UV-C-equipped devices offer low running costs and are maintenance-free, besides normal bulb replacement. These powerful and highly durable systems provide exceptional value for money. For this reason, eliminating germs using UV-C as opposed to (or together with) other systems offers excellent results at a low cost.

The effect of UVC on viruses
The virus information is contained in the capsid in the form of single-stranded DNA or RNA. Whether RNA or DNA, the mechanism of UVC destruction of these molecules is very effective. The radiation penetrates the viral envelope and hits the genetic material. As with DNA, RNA forms pyrimidine dimers and additional uridine hydrates. The information for reproduction is lost, the virus is no longer virulent and the infection cycle is
broken.
Depending on the virus, a certain dose of UVC is needed to block it. The lethal dose needed to destroy 90% of a virus type is called LD90 . With influenza viruses it is simply done with 2 mJ/cm², with Corona there are
unfortunately very few values, but most experts consider an LD90 of 2.5 mJ/cm² to be realistic. However, it is also important whether the viruses are to be inactivated in the air, droplets, sputum, blood or water. To disinfect a smooth surface even to 99.9 %, about three times the LD90 dose is required, i.e. between 7.5 and 10 mJ/cm² for corona viruses.
