Osram Puritec HNS S

Osram Puritec HNS S

These germicidal lamps are low-pressure lamps that emit mercury line radiation mainly in the short-wave ultraviolet range. They are the highly promising eco-friendly alternatives to chemical purification processes.

They do not use any chemicals and are environmentally friendly. They are available in different sizes and outputs to suit different requirements.

Osram offers many different lamps for effective disinfection in a wide range of applications.

The main lines in the spectrum are at 254 nm and 185 nm. Ultraviolet light, which has a wavelength of less than 240 nm, produces ozone. This high energy radiation can pass through the quartz glass used for ozone-generating lamps.

If ozone is not required then special glass or appropriate types of quartz are used. They are transparent for the radiation that kills micro-organisms but do not let ozone-generating radiation through. HNS® lamps are manufactured as undoped lamps and as amalgam-doped lamps. The undoped lamps achieve their optimum wall temperature of 40 °C at an ambient temperature of around 25 °C. The amalgam lamps, on the other hand, typically reach temperatures around 100 °C and are less sensitive to ambient temperature.

Main applications

  • Air purification
  • Water purification and cleansing
  • Surface disinfection
  • Odor elimination
  • Erasing of Eproms
