PURITEC HNS UV-C lamps

Purification with UV-C light

Most people do not think of light as a means of purifying or disinfecting, but special "germicidal" lamps emit high intensity ultraviolet light that purifies air, water, and surfaces without the use of harsh chemicals that are harmful to the environment.

Why UV

UV light offers a solution to the problems posed by contaminated water. Home UV systems—integrated into the plumbing—and portable UV filters—for on the go—allow people to live where they want and travel where they wish, always ensuring access to clean, safe water.

Background Knowledge

  • Photolytic effect on DNA: micro-organisms such as bacteria, moulds, yeasts and viruses cannot replicate.
  • Purification effect is obtained at wavelengths below 320 nm, with maximum effectiveness achieved at 260 nm.
  • OSRAM HNS germicidal lamps emit light at 254nm, very close to the maximum effectivness and are ozone-free
