Micro-organisms are microscopically small. They are everywhere and have an extremely high metabolism. For example, in hot and humid weather the number of moulds and bacteria increases exponentially.
Furthermore, micro-organisms produce mucus substances that are deposited on surfaces and can contaminate food and cause microbial decay of the products.
The cell nucleus of micro-organisms contains thymine, a chemical element of the DNA / RNA. This element absorbs UV-C light at a specific wavelength of 253.7 nm and changes to such an extent (formation of thymine dimers) that the cell is no longer capable of multiplying and surviving.
This process has a lethal effect on all microorganisms such as bacteria, fungi, moulds, yeasts and viruses.
Germicidal UV has been used safely and effectively in industry, healthcare, institutions & commercial / domestic premises for more than 100 years.
