One of the best-known natural sources of ultraviolet (UV) radiation is the sun, which emits sunlight and radiates heat to planet Earth.
Besides the sun, there are other unnatural sources of ultraviolet radiation emission, the best known being fluorescent lamps, which emit little ultraviolet radiation. In the industrial area, UV radiation is present in the most diverse industries, food, automotive, health and chemical are examples of industrial areas that use UV in their processes or products.
According to the definition, ultraviolet radiation can be considered as all electromagnetic radiation with a wavelength between 100nm and 400nm, this wavelength range is due to three main types of UV rays: UVA with a wavelength range between 315nm and 400nm, UVB with a wavelength range between 280nm and 315nm and UVC with a wavelength range between 200nm and 280nm.
In addition to these three types, there is also the wavelength range from 100nm to 200nm, which is considered the UV vacuum range, where the wavelength is absorbed by the air and starts to propagate through nitrogen.
UVA: Rays with greater incidence on planet earth as they are not absorbed by the ozone layer.
UVB: Rays partially absorbed by the ozone layer.
UVC: These rays are 100% absorbed by the ozone layer and have a bactericidal sterilization factor due to their wavelength.
Due to its photochemical action, ultraviolet rays have many applications, the most common being beauty and skin care, forgery detection, document verification, crime scene inspection, gem and mineral inspection, non-destructive testing, curing of paints and surfaces, and sterilization or germicidal action.
Formation of ultraviolet light in lamps.
By energizing atoms, through heat, gamma radiation, X-rays or cosmic rays, electrons can absorb energy and jump into outer orbitals.
On the way back, ionization occurs, that is, the energy is returned in the form of ultraviolet light, visible or invisible, depending on the electron energy jump and the type of lamp.
One of the ways to control the growth of microorganism colonies is with ultraviolet C (UVC) by ray disinfection systems. This type of system, in general, has a source of germicidal action, which uses specific lamps, and its ray emission is capable of neutralizing microorganisms, whether they are arranged on surfaces, in suspension or in passage (controlled flow).
Due to the photochemical reaction, exposure to UVC rays causes changes in the genetic material of the microorganism cells, making them sterile, thus preventing their proliferation.
Sensor Technology has a specialized team in industrial sterilization projects via ultraviolet ray emitters. We offer the most modern disinfection solutions for a large rangeof industrial areas, ensuring the safety of processes, integrity of employees, compliance with current standards and with the specifications required for the project.
How it works:
By identifying which colonies are present in the place that requires sterilization, the sizing of the UV system can be determined to avoid the proliferation of these microorganisms. They are hindered as result of the ultraviolet rays directly affecting the cellular structures of each of the microorganisms, therefore, the exposure to ultraviolet rays makes these organisms sterile, preventing their proliferation.
The effectiveness of the inactivation can be determined based on the controlled emission of UV rays achieving 99.9% of microorganism inactivation when the colonies are known and with correctly sized projects.
As the systems are developed on demand and according to each need, the Sensor Technology UV disinfection systems are effective in sterilizing surfaces, environments and products in general, recognized in the market for their excellent performance and excellent cost-effectiveness.
