HOW UV-C WORKS

THE UV SPECTRUM

UV-A results in skin tanning and is used in medicine to treat certain skin disorders.
UV-B has a very high penetrating ability and results in sunburn. Prolonged exposure is responsible for some types of skin disease, skin ageing and cataracts.
UV-C has extremely low penetrating ability and is nearly completely absorbed by the outer, dead layer of skin where it does little harm. This type of radiation is filtered out by the ozone layer so that none reaches the earth’s surface.

Existing technology makes use of the bacterial effect of UV-C light through UV-C sanitation.

WHAT IS UV-C?

Ultraviolet light in the C spectrum (UV-C) is energy-rich light with a wavelength of 200 – 400 nanometers (nm).
It is very versatile and can be used for disinfecting water, destroying harmful microorganisms in other liquids, on surfaces, on food products and in ‘air’.
Ultraviolet C is germicidal.

WHAT IS GERMICIDAL ULTRAVIOLET?

It is a non-chemical approach to disinfection.
It deactivates the DNA of bacteria, viruses and other pathogens** and destroys their ability to multiply and cause disease. Specifically, UV-C light causes damage to the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA. The formations of such bonds prevent the DNA from being unzipped for replication, and the organism is unable to reproduce. In fact, when the organism tries to replicate, it dies.
It has lethal effect on all microorganisms such as bacteria, fungi, molds, yeasts and viruses.
