Different Solutions for Different Needs

365DisInFx UVC Logo

Air Disinfection

UVC solutions can help reduce viruses in air.  Based on testing, 365DisInFx® LPU Gen2 devices are predicted to provide 90% inactivation of aerosolized SARS-CoV-2 (the virus that causes COVID-19) in the first hour or less of exposure when used as directed.1

Surface Disinfection

UVA solutions can help reduce bacteria and fungi on surfaces. Our in vitro testing with eight hours of exposure has shown significant reductions in common pathogens associated with hospital-acquired infections (HAIs), such as MRSA, Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Acinetobacter baumannii, Pseudomonas aeruginosa, Candida albicans and auris.2

Make an Informed Decision

  • UV radiation can pose a risk of personal injury. Overexposure can result in damage to eyes and bare skin. To reduce risk of overexposure, equipment must be installed in accordance with site planning and application recommendations.
  • UV solutions are intended for common high traffic spaces and not recommended for dwellings or home use.
  • Installation of the devices should be performed by qualified professionals as detailed in Current’s installation guide
  • To allow for occupancy during use, Current products comply with UL 8802 Outline of Investigation for UV Germicidal Equipment and Systems, IEC 62471 Photobiological Safety of Lamps and Lamp Systems standards, and American Conference of Governmental Industrial Hygienists (ACGIH®) TLVs® guidelines over an 8-hour period when installed as directed.
  • Current's UV products are meant to be used in conjunction with other protective measures like manual cleaning and the use of proper PPE. They are not a substitute for other measures.
  • Current products are not intended to be used as a medical devices.
  • When combining two or more UV solutions, whether from GE Current, a Daintree company and/or other manufacturers, please consult a trained product application representative to ensure the total irradiance (UV dose) does not exceed recommended human exposure limits. To the extent UV solutions are combined, it may affect the deactivation rates.

UVC Test Results

GE Current, a Daintree company, has completed room-scale tests of its 365DisInFx® UVC disinfection technology LPU series devices that show reduction of the aerosolized viruses SARS-CoV-21 (the virus that causes COVID-19), and bacteriophage MS22

Applying photobiological science and mathematical modeling to the results of device testing and published literature, continuous operation of a properly installed array of  365DisInFx® LPU Gen2 devices is predicted to provide 90% (1-log10) inactivation of aerosolized SARS-CoV-2 in the first hour1 or less of exposure and 99% inactivation (2-log10) in 2 hours or less of exposure in most spaces when configured for an 8-hour or greater Permissible Exposure Time (PET) as defined in IEC 62471 – Photobiological Safety of Lamps and Lamp Systems standards at 7 foot head height. Current continues to conduct additional supporting experiments.

1Testing with the SARS-CoV-2 using LPU devices with prototype refractive optics resulted in 90% inactivation of the aerosolized virus within 2 hours. This testing was then used as the basis for photobiological science and mathematical modeling. The test was conducted in an 8-by-20-by-8-foot room equipped with twelve LPU devices using prototype refractive optics, configured for 8-hour Permissible Exposure Time (PET) at head height (7 feet). SARS-CoV-2 Isolate USA-CA1/2020 was used in this testing, and results are expected to be applicable to other SARS-CoV-2 isolates or strains, including B.1.617.2 (Delta) or other Variants of Concern or Interest, as well as to seasonal human coronaviruses.

2Testing with the bacteriophage MS2 resulted in 88% inactivation of the aerosolized virus within 4 hours. The test was conducted in a 10-by-10-by-8-foot room equipped with seven LPU prototype devices, configured for a 4-hour Permissible Exposure Time (PET) at head height.  Bacteriophage MS2 is a nonenveloped virus that is commonly used as a surrogate in testing for viruses that are pathogenic to humans. It is particularly useful as a surrogate whereas published scientific testing and literature supports that bacteriophage MS2 is more resistant to UVC than certain enveloped viruses such as coronaviruses and influenza.

 

UVA Testing, Lab Results & Notes

365DisInFx® UVA disinfection technology was tested using in-vitro methods as described in detail in Citations 1 & 2 below (Livingston, Kvam) which resulted in 99.7% reduction in MRSA on surfaces exposed to 3W/m2 of 365nm UVA over a single 8-hour period. Results of this testing demonstrated significant reduction over a similar exposure period of certain common pathogens including MRSAStaphylococcus aureus, Enterococcus faecalis, Escherichia coli, Acinetobacter baumannii, Pseudomonas aeruginosa, Candida albicans and auris, associated with Hospital Acquired Infections (HAIs). Photobiological science and mathematical modeling enables us to calculate expected inactivation rates for 24-hour continuous operation of the 365DisInFx® UVA technology.
