Sanitization of GUVC Lamps

What are UV-C?

UV stands for ultraviolet light. Ultraviolet light represents the frequency of light between 200 nanometers (nm) and 400nm and cannot be seen by the naked eye. Within the UV spectrum are three distinct bands of light: UV-A, UV-B, and UV-C. Long-wave UV light (315nm to 400nm), or UV-A, is referred to as what we commonly call “black light.” UV-B (280nm to 315nm), or mid-range UV, causes sunburn. Germicidal UV light (200nm to 280nm), or UV-C, is effective at microbial control. Research has shown that within this UV-C band the most efficient frequency for microbial destruction is between 254nm and 265nm. Germicidal Lamps that produce the majority of their output in this range will be the most effective at microbial control/destruction.

Why choose GUVC Lamps?

GUVC systems emit ultraviolet light with a peak of 253.7 nm. The Germicidal action of the GVU-C unit is able to eliminate Bacteria, Viruses, Fungi, Spores, Molds and Mites by destroying their DNA, and inhibiting their reproduction and proliferation.
GUVC technology allows physical disinfection with an excellent cost/benefit ratio. Furthermore, it does not use chemical agents, does not release unwanted substances and works against all microorganisms without creating resistance.

Effective against all microorganisms, such as: Bacteria, Viruses, Spores, Yeasts, Molds, Mites, Protozoa, Algae; by destroying their DNA, it inhibits their reproduction and proliferation.
Ecological system, without chemical agents.

Specific regulatory scope

From a regulatory point of view, it should be noted that, since the disinfectant activity of ultraviolet radiation is carried out through a physical action, disinfection systems based on UV-C do not fall within the scope of the BPR which expressly excludes from the definition of biocide, products that act through physical and mechanical action. Also at a national level, according to the Presidential Decree of 6 October 1998, n. 392 on PMC, products whose disinfectant activity operates through physical or mechanical action are not included.

Technical-scientific evaluation

Typically, germicidal lamps used in sterilization systems have a dominant emission around the wavelength of 253 nm (nanometers). Components with a wavelength shorter than 250 nm are generally filtered to prevent the risk of ozone production. In these cases the lamp is defined as “ozone free”. If the UV components with a wavelength shorter than 250 nm are not shielded, safety procedures must also be implemented to prevent exposure to ozone, indicated in the paragraph “Ozone Treatment”. UV-C radiation has the ability to modify the DNA or RNA of microorganisms, preventing them from reproducing and therefore being harmful. For this reason, it is used in various applications, such as the disinfection of food, water and air.

Virus Inactivation

In vitro studies have clearly demonstrated that UV-C light is capable of inactivating 99.99% of aerosolized influenza viruses. The virucidal and bactericidal action of UV-C has been demonstrated in studies on the MHV-A59 virus, a murine analogue of MERS-CoV and SARS-CoV1. Application to droplets containing MERS-CoV resulted in undetectable levels of the MERS-CoV virus after just 5 minutes of exposure to the UV-C emitter (a percentage reduction greater than 99.99%) and was also effective in sterilizing blood samples. In particular, inactivation of over 95% of aerosolized H1N1 influenza virus has been demonstrated using a nebulizer capable of producing aerosol droplets similar in size to those generated by human coughing and breathing.
