Christie® CounterAct™ products with patented Care222® technology
CounterAct commercial UV disinfection fixtures contain Ushio Inc.’s patented Care222 lamps that emit far-UVC 222nm light that’s shown to significantly reduce surface pathogens in occupied and unoccupied indoor spaces. It’s the only far-UVC germicidal technology that may also be used around people, and the only with a proprietary filter that prevents longer UVC wavelengths from being emitted.
»Feature
• Easy-to-use as easy to install as traditional commercial lighting fixtures, with maintenance via an app.
• Instant on/off at full output power, and frequent on/off cycles don’t affect lamp life.
• Remote monitorable for easy programming and troubleshooting.
• Easy-to-service for straightforward lamp changes.
• Fixtures are available in black and white to fit existing color schemes.
• Available in both AC and DC power configurations.
• Flexible leasing options are available.
»Difference between UVC-254nm and UVC-222nm
This graphic illustrates a significant difference between 254nm and 222nm light: the shorter wavelengths of far-UVC 222nm light have a limited ability to penetrate past the outer layer of our skin. This layer, the stratum corneum, consists of dead skin cells and serves as the primary barrier between our bodies and the environment. Conversely, longer wavelengths like 254nm are able to deeply penetrate the layers of our skin, and can damage the DNA in our skin cells, causing burns and skin cancers.
This graphic clearly illustrates how 254nm (and longer) wavelengths are able to damage our eyes—including incurable diseases like macular degeneration—because wavelengths of 230nm and above can penetrate our eyes. Shorter wavelength 222nm light has a limited range that prevents it from penetrating past our corneas, the outermost layer of our eye.
