UVC GERMICIDAL IRRADIATION (UVGI) TECHNOLOGY & NEWS



Upper-Room Ultraviolet Germicidal Irradiation (UVGI)



Share Link from CDC Website





CDC recommends a layered strategy to reduce exposures to SARS-CoV-2, the virus that causes COVID-19. A layered strategy combines multiple prevention strategies such as consistent and correct use of masks, ventilation, physical distancing, cleaning and disinfection, and hand hygiene.

What Should Considered During Implementation of all UVGI systems?



Call us for consultation





  • UVGI lamp fixtures must be carefully installed >2.1 meter (Must have baffles or louvers if lower than that) to minimise exposure of UV-C to occupants in the room. The exposure to UV incident radiation on unprotected skin or eyes should be within the limits (8 hr exposure: 6 mJ/cm2 for 254 nm)
  • UV-C systems should not generate ozone gas (<0.05 ppm, 8 hr) JKKP Code of Practice 2010 for Indoor Air Quality for Air-Conditioned Buildings.
  • All organic material components within 1.5 m of the UV lamp should be shielded, as UV-C energy can be detrimental to organic materials (e.g. plants, certain filter media and insulation or gasket foams in ACMV systems, wood surfaces, and wallpapers).
  • Regular verification of the performance of the UV-C systems should be carried out after installation to ensure continued safety and efficacy.
  • Measurement should be taken in the lower room to estimate the UVGI exposure level of room occupants.
  • Measurement of Lamp at least 1.2m away. Average measures should be 30uW/m2 to 50uW/m2.

some considerations when implementing upper-room UVGI.



Call us for consultation





  • UV irradiation should be distributed uniformly and parallel to the plane of the ceiling. (With UV dose of 30µW-sec/cm2 to 50µW-sec/cm2 , if 254 nm wavelength is used) should be maintained in the upper irradiation zone.
  • The minimum ceiling height in a room should be 2.6 m, with upper room UVGI installed at heights of 2.1 m and above.
  • Systems should be designed and operated to provide optimal airflow patterns and prevent air stagnation. Fans can be used if air is not well mixed vertically between the lower and upper portions of the space.
  • Relative humidity in the room should be less than 60% if attainable, as levels over 80% may reduce the effectiveness of the UV-C systems.
  • Installation of upper-room UVGI systems should be carried out by professionals to ensure that the UV-C irradiation is directed above the occupied space, and that the irradiance levels in the lower occupied room do not exceed the acceptable limits (e.g. 0.2 µW/cm2 for 254 nm based on 8 hr exposure).

UVGI and SARS-CoV-2



Call us for consulation





  • To date, UV research on SARS-CoV-2 indicates that the virus that causes COVID-19 is very similar to other coronaviruses (for example, SARS and MERS) regarding the UV dose necessary to inactivate it.
  • Upper-room UVGI systems can be used to control SARS-CoV-2 as a useful ventilation tool to consider in reducing the spread of infectious pathogens.
  • UVGI does not replace the need for cleaning or disinfecting surfaces where infectious SARS-CoV-2 droplets may be present
