Supply Air Disinfection Module for Air-Conditioning and Ventilation Systems

Supply Air Disinfection Module for Air-Conditioning and Ventilation Systems

Eliminating microorganisms created inside ventilation ducts as well as those acquired externally – Reducing germ levels via UV-C lamps


  • An air disinfection system for sterilizing airflow in air-conditioning and ventilation systems
  • Effectively destroys bacteria, viruses, yeast, and mold spores occurring in supply air
  • Protects employees from pathogens
  • Increases food shelf life
  • All components are UV resistant


  • Air-conditioning and ventilation systems for factories, administration buildings, public buildings, social institutions, hotels, cruise ships, etc.


  • Avoiding bad batches
  • Reducing sick leave
  • No germ resistance
  • No use of chemicals or filters
  • No byproducts (e.g., nitrogen oxides)
  • Low operating costs
  • Low energy consumption

Air drawn in from outside is directed over high-power UV-C lamps inside an air-conditioning duct module. These low-pressure mercury vapor lamps emit UV-C radiation with a precise wavelength of 253.7 nm; this is the spectrum that reliably destroys germs. In this way, microorganisms that have penetrated from the outside are destroyed and the whole ventilation system is also kept germ-free.
