Sanitizing 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 with the naked eye. Within the UV spectrum there are three distinct bands of light: UV-A, UV-B and UV-C. Long-wave UV light (315nm to 400nm), or UV-A, refers to what we commonly refer to as “black light”. UV-B (280nm to 315nm), or mid-range UV, causes sunburn. Germicidal UV light (200nm to 280nm), or UV-C, is effective in microbial control. Research has shown that within this UV-C band the most efficient frequency for microbial destruction is between 254 nm and 265 nm. Germicidal Lamps that produce the majority of their production in this range will be most effective in 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, Fungus, 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. It also does not use chemicals, 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. Maximum efficiency thanks to the quartz tube Germicidal emission 253.7 nm Quick Couplings, Flanges and Supports for professional installation.

Specific regulatory framework
From a regulatory point of view, it should be noted that, since the disinfectant activity of ultraviolet radiation is implemented through an action of a physical nature, 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. According to the DPR 6 October 1998, no. 392 on PMCs, products whose disinfectant activity operates by physical or mechanical action.
Technical – scientific evaluation
Typically, the germicidal lamps used in sterilization systems have a dominant emission around the wavelength of 253 nm (nanometers). Components with a wavelength of less 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 of less than 250 nm are not shielded, the safety procedures to prevent exposure to Ozone must also be implemented, as indicated in the “Treatment with Ozone” paragraph. 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.
In vitro studies have clearly shown that UV-C light is able to inactivate 99.99% of the influenza virus in aerosols. The virucidal and bactericidal action of UV-C rays has been demonstrated in studies on the MHV-A59 virus, a mouse analogue of MERS-CoV and SARS-CoV1. Application to droplets containing MERS-CoV resulted in undetectable levels of the MERS-CoV virus after only 5 minutes of exposure to the UV-C emitter (a percentage reduction greater than 99.99%) and were also effective in sterilizing blood samples. In particular, the inactivation of more than 95% of the H1N1 influenza virus aerosolized by a nebulizer capable of producing aerosol droplets of similar size to those generated by human coughing and breathing has been demonstrated.
