    What are the advantages of SUMINZI over other disinfection technologies?

    It does not harm the skin and eyes, continues to be efficient, acts on the air and surface at the same time, is non heating, non-contact, non chemical sterilization, has no residue, does not rely on labor, and is not affected by the ambient temperature.

    What is UVC?

    The ultraviolet radiation of the sun can be divided into three bands (100nm-400nm) according to the ultraviolet radiation of the sun: a) UVA: 315-400nm, without bactericidal and viral effects, but can be used to slow down the growth of bacteria, which will lead to skin tanning. b) UVB: 280-315nm, high energy, can kill bacteria, but it has poor effect on viruses with much smaller particle size. This band has a great impact on the human body. Proper irradiation can treat and prevent rickets. Long term irradiation may also damage the skin and eyes, and even cause skin cancer, cataract, decline of immune system function and other diseases; c) UVC: 200-280nm, high energy, very suitable for killing microorganisms. d) VUV, with a wavelength range of 100-200nm, is almost absorbed by ozone, water vapor, oxygen and carbon dioxide and cannot reach the ground. All ultraviolet rays are invisible.

    Why does SUMINZI use a short wave bandpass filter?

    Because the KrCl excimer module emits the ultraviolet spectrum with the central wavelength of 222 nm, and also emits ultraviolet rays in high hazard bands such as 235 nm and 254 nm. The special narrow wave band-pass filter can filter out harmful wavelengths and only transmit far ultraviolet rays in the band of 200 ~ 230 nm, so as to ensure the sterilization effect and do not harm the skin and eyes.

    Can all ultraviolet rays be used as bactericidal UV?

    No, germicidal ultraviolet (GUV) refers to short wave ultraviolet rays that have been proved to kill bacteria and spores and inactivate viruses.
  • 03

    Can the SUMINZI only be installed on the 2.5-meter-high ceiling?

    No. The recommended installation height of SUMINZI is 2.5m-5m, but the sterilization effect is related to time and height, that is, 99.9% of the virus is also killed. The higher the layer is, the longer the time is required.

    Can UV-C kill viruses and bacteria?

    Yes, UV-C is absorbed by the DNA and RNA of bacteria, viruses and other cells. The nucleic acid structure of cells that absorb UV-C is damaged due to the formation of dimers, loss of reproductive ability and death. This is the mechanism of UV-C sterilization and inactivation of viruses.

    What is the scope of SUMINZI disinfection?

    If a sterilizer is installed on the 2.5m high ceiling, it can effectively disinfect a room of 4.5 × 3.9m.

    Can UV-C effectively inactivate the sars-cov-2 virus that causes covid-19?

    Yes, if the virus is directly irradiated by UV-C at the effective dose level. UV-C can play an effective role together with other disinfection methods.
