Christie to mass produce CounterAct with Care222, a safer, filtered far-UVC disinfection technology for use around people
As we prepare for a post-pandemic world where reducing pathogens and viral spread is essential, global visual technology company Christie has announced the mass production of its Christie CounterAct line of commercial UV disinfection products with patented Care222 far-UVC light technology.
CounterAct fixtures are designed for use in occupied indoor spaces, from cinemas, theme parks, museums and sports complexes, to retail facilities and restaurants, as well as transit hubs at airports, train and subway stations.
Developed by Christie, and using parent company Ushio's Care222nm UV lamp technology which is is licensed through Columbia University, the CounterAct line of mounted fixtures is designed for high-ceiling applications, which can be installed as easily as commercial lighting fixtures.
Thought to be the first UV disinfection technology developed for use around people, Christie CounterAct uses proprietary filtered far-UVC light to eliminate 99% of pathogens on surfaces in indoor spaces, including the SARS-CoV-2 Coronavirus which causes Covid-19, influenza, bacteria, and other antibiotic-resistant superbugs by damaging the DNA or RNA of the pathogen, which leaves them unable to reproduce and infect humans.
"With our CounterAct fixtures, as an added layer of defencee, bringing customers back to the places they love to share and create memorable experiences, has never been safer," promises Brian Claypool, executive vice president, Cinema, Christie. "Many businesses and industries all over the world rely on being able to have their customers together in person, and they will need every tool available to help them do so safely."
To date, Christie CounterAct models have demonstrated compliance with UL, CE and UKCA by third-party testing facilities for electrical safety, electromagnetic compatibility (EMC), compliance with the radio equipment directive, and most importantly photobiological safety.
Photobiological compliance is a safety evaluation to confirm that the level of UV exposure for occupants is in line with accepted industry guidelines - a critical component of the third-party testing.
UV light has long been proven to effectively neutralise pathogens, but the 254nm wavelength used in many other disinfection products on the market is a human health hazard because it can penetrate and damage human eyes and skin, making it unsafe for human exposure.
Award-winning CounterAct fixtures contain Ushio's patented Care222 lamps that emit far-UVC 222nm light - which was shown in a 2020 study by Kobe University to be safely used with people present, making it a sweet spot on the UV spectrum that's effective against pathogens in occupied spaces. Additionally, Care222 is said to be the world's first far-UVC technology with a proprietary optical filter that blocks potentially harmful longer (>230nm) UVC wavelengths from being emitted.
"The fact that the unique far-UVC light from our Christie CounterAct UVC disinfection fixtures can be used automatically and continually in the presence of people is the key advantage,” explains Brian Claypool. “The technology reduces pathogens from the environments where people gather. By harnessing these benefits as part of a user-friendly product that can be quickly deployed, we hope to provide a much-needed boost to our partners across many industries.”
