Air sterilisation (UVPE)


IST METZ has been producing UV systems for curing inks, coatings and silicones for over 40 years. What many do not know: The emission of UV lamps also inactivates the DNA of harmful microorganisms. With the Steritube systems, which UV plant manufacturer IST Metz sells together with its partner and air disinfection specialist Virobuster, 99.9% of the microorganisms in the ambient air are killed using UVC technology.

Active principle of Steritube

  • Air with potentially infectious viruses & bacteria is passed through an UVPE field (ultraviolet pathogen elimination)
  • The DNA is blocked by the UV-C light and further cell division or reproduction is prevented
  • The infection potential of more than 99% of all viruses, bacteria and fungi is eliminated 

Risk of aerosols in the air

Most common types of transmission of microorganisms:


  • droplet contact
  • Aerosol inhalation
  • (Surface) smear infection


When we speak and breathe, aerosols are excreted, which float in the air for long periods of time and spread throughout the rooms1. The reduction of fungi, bacteria and viruses therefore has a significant effect on air quality.


While additional ventilation costs extra energy and is not easy to set up, a sterile base system can perform six air changes per hour in a 50 m3 room. This results in the deactivation of 90% of the initial air pollutants within 23 minutes.
