The process

UV Sources amplify a natural phenomenon

The sun has a health-giving effect produced by the emission of invisible light.

This natural phenomenon is used and amplified by ABIOTEC's powerful UV sources.

The DNA and RNA in micro-organisms (viruses, bacteria, yeasts, moulds, etc.) are damaged by UV wavelengths (200 to 315 nanometres). This in turn inhibits replication of the genetic material and kills the micro-organism or prevents it from reproducing.

All germs can be inactivated in this way, even if they do not all have the same UV sensitivity.
