UVGI SYSTEMS

UVGI SYSTEMS

UVGI is a disinfection method that uses UV-C light to eliminate or inactivate micro-organisams, such as bacteria, viruses, moulds and other pathogens. UV-C is a type of ultraviolet at wavelength of 280 – 200 nanometre, which is the most effective wavelengths for germicidal control. It can be used to prevent the spread of certain infectious diseases. As a supplemental air-cleaning measure, UVGI is effective in reducing the transmission of airborne bacterial and viral infections in hospitals, military housing, and classrooms, but it has only a minimal inactivating effect on fungal spores.223–228 UVGI is also used in air handling units to prevent or limit the growth of vegetative bacteria and fungi. Most commercially available UV lamps used for germicidal purposes are low-pressure mercury vapor lamps that emit radiant energy predominantly at a wave-length of 253.7 nm.2

Ultraviolet germicidal irradiation, or UVGI, is the use of ultraviolet (UV) energy to kill viral, bacterial, and fungal organisms. UVGI fixtures produce UV-C energy, which has shorter wavelengths than more penetrating UV-A and UV-B rays and pose less risk to human health. Upper-room UVGI refers to a disinfection zone of UV energy that is located above people in the rooms they occupy. This kills airborne pathogens in the room where they are released. Fixtures are installed to prevent direct UV exposures to people in the room. Ultraviolet germicidal irradiation (UVGI) has been used to‘‘scrub’’ the air in health care facilities and laboratories for many decades. UVGI is known to be efficacious to varyingdegrees in controlling the circulation of airborne infectious particles. Approximately 60% of all UVGI air disinfection systems are installed in health care facilities.

  • Room air is circulated and disinfected through the air sterilisation system using built in UV-C LED in the ducted fan coil
  • UV-C LEDs are installed in a specific angle to ensure optimal air treatment
  • UV-C LEDs are specially designed with enhancing reflector for more concentrdtQd UV-C light achieving better disinfection effect
  • Suitable for small and medium space applications.
  • In AHU air chamber space, UV-C lamps can provide greater intensity output and higher disinfection effect.
  • UV-C lamps are installed in AHU for coil sterilization and surface disinfection.
  • UV-C lamps target and irradiate the cooling coil and condensate drain pan.
  • Suitable for large space applications

Use ultraviolet C-band energy to kill or inactivate the microorganisms
