ISO Italia Group is an Italian company with 30 years of experience in the electromedical equipment sector, oriented towards continuous improvement and technological development thanks to partners present all over the world. Through the ISO Italia brand we produce UVA - UVB tanning equipment and with ISO Benessere equipment and furnishings for beauty centers and spas.

Steril Line is our line for sanitizing environments through disinfection systems with UVC germicidal lamps. Our design and production is entirely Made in Italy and is sold worldwide.



Steril Line's mission is to offer solutions for the sanitization of public and private environments, surfaces, everyday objects and air.

Each germicidal technology that we make is designed with the aim of improving the quality of the environment in which we live. We think of equipment that gives safety to those who use them and those who frequent the places where they are installed.

Our projects are always based on official and international documentable scientific studies.

What has always distinguished us and in which we will continue to develop our research is the creation of equipment dedicated to wellness, quality of life, safety for health, the community and the environment, together with attention to technical quality of our products and professional ethics.


The Zonta family began producing tanning equipment in 1980. Only in 1986, after having gained considerable experience in the sector, the family founded its own brand: I.SO Italia.

The continuous search for quality, design and efficiency on each product made has allowed I.SO Italia to be known and appreciated as one of the most important companies in the national and international panorama of manufacturers of electromedical equipment.


In 2013 the company grew and Iso Italia Group was born, which continues production and distribution with three specialized brands: lSO Italia, ISO Benessere and Steril line.

All characterized by a constant commitment in research and development, particular attention to quality control and market needs and innovative scientific-technological research.

The last born brand is Steril-line. The result of over 30 years of consolidated experience in the UV lamp sector. By taking advantage of highly technological and cutting-edge solutions, the goal of the products of this brand is to offer its contribution to the safety of public and private health through the production of efficient and reliable equipment.


UVC disinfection systems,
germicidal ultraviolet radiation

Ultraviolet (UV) rays are electromagnetic radiation emitted by the sun, whose wavelength is positioned between visible light and ionizing radiation, such as X and gamma rays.

The term means "beyond violet" (from the Latin ultra, "beyond"), since violet is the color with the highest frequency in the spectrum visible by man.

Wavelengths ranging from 200 to 250 are called UVC and are harmful to viruses, bacteria and other microorganisms.

At a wavelength of 254 nm, UV destroys the molecular bonds of the DNA of microorganisms, making them harmless and preventing their growth and reproduction.


How does a germicidal lamp work?

A germicidal lamp is a particular type of lamp that produces UV-C ultraviolet light, a frequency capable of breaking down 99.9% of pathogenic microorganisms such as viruses, mold bacteria present in the air and on surfaces.

Ultraviolet rays are also used as an energy source for catalytic combustion which is a process of air purification that reduces pollutants by oxidation. UV-C rays are harmful to humans, who cannot be directly exposed to them. For this reason it is necessary to equip each device with systems that make its use safe.



The germicidal action of ultraviolet radiation was discovered in the late 1800s and initially used to sanitize polluted water and make it drinkable. These systems are already widely used for medical and laboratory sterilization, but can be used for the disinfection of air, water, surfaces and sterilization of objects in both professional and domestic settings.



There are two types of sanitizing products, which can be used individually, for a lowering of the risk, or simultaneously, for a total disinfection.


  • Air purification systems
    Through a silent ventilation system, the air is introduced into the purifier chamber equipped with germicidal UVC lamps and is purified, returning sterilized air. These systems can remain constantly active in the presence of people without the need for turn-over times.
  • Systems for surface purification
    UVC sources inactivate the proliferation of spores, viruses and bacteria in proportion to the energy with which they affect them. So a room irradiated with UVC light is sterilized in a few minutes. Obviously the irradiation power (number and power of the lamps) must be proportional to the size of the room and during irradiation there must be no people present. Common applications include surgeries or small rooms but also hospitals, auditoriums, laboratories, operating rooms, etc.
  • Systems for the purification of objects
    With the same principle of efficiency, UVC lamps can be installed inside containers (wardrobes, drawers etc.) and turned on, to sanitize what is placed inside them in a few minutes. Masks, equipment / tools of all kinds, keys, mobile phones, containers, gloves etc. etc.


UV-C disinfection systems do not require maintenance or specialized personnel, they are safe and easy to use. They are eco-sustainable as they do not require the use of other chemical solvents and do not release residues of any kind.

The guaranteed effectiveness of UVC systems

By the amount of energy produced by each UVC lamp and by the number of lamps installed in the equipment, multiplied by the time of use, we can establish the "DOSE" of UVC produced by each of our systems. This gives us the certainty of germicidal efficiency since tables that indicate the "DOSE" UVC for its elimination for each bacterium, spores and viruses are used medically and internationally.

As an example, an extract from the table:
