UVGI device for Cabin FCU and UVGI device for Public FCU
UVC-light radiation can be used to destroy harmful pathogens, such as bacteria and viruses. 200 to 300 nm wavelength radiation is strongly absorbed by living organism’s nucleic acids (RNA and DNA) which are damaged in the process. This is also called Ultraviolet Germicidal Irradiation (UVGI).
Fluorescent UVC light tubes produce 253.7 nm wavelength radiation. In this kind of air purification application, UVC light tubes are installed inside of air duct. Radiation reduces the number of pathogens in airflow.
The general scientific consensus is that viruses are very susceptible to UVC radiation and even small radiation doses can inactivate viruses. Radiation dose is the factor of radiation power, distance to radiation (surface area) and residence time in the irradiation zone. Lower flow velocity increases residence time. This is optimal for performance.
Halton Marine UVGI tubes have been tested at Helsinki University against test pathogens. UVGI tubes are of the type that does not produce ozone.
