Hydroxyl Generators
Developed for NASA astronauts
Photocatalytic Oxidation (PCO) hydroxyl generators were originally developed by NASA as part of its Advanced Technology program for astroculture to remove ethylene from air with a unit that does not require any consumables. Further research discovered Photocatalysis had “potential for use in a number of NASA applications. The most obvious application for the removal of unwanted gas(es) from moderate and long-term confined areas, as in Space Shuttle cabins and in the International Space Station.” It was determined that “..using photocatalysis to eliminate pollutants from confined spaces could be derived for NASA ... as well as for the general use of photocatalysis in non-NASA applications”.
Care222® Filtered Far UV-C Excimer Lamp Module
Filtered Krypton-Chloride 222nm Technology
Ushio is proud to introduce the Care222® series, our line of filtered 222nm Far UV-C excimer lamp modules for microbial reduction applications.
Filtered Care222 modules can be safely used in unoccupied and occupied spaces without posing a health risk to humans when used within the current exposure limits recommended by the American Conference of Governmental Industrial Hygienists (ACGIH®) or the requirements of IEC 62471. Exposure within the current ACGIH recommendations and IEC requirements allow microbial reductions using 222nm far-UVC light sources in occupied spaces. Recent studies indicate that higher doses of filtered UV light emitted from the Care222 modules pose a minimal health risk to human skin or eyes.
Features of the Care222 module allow customers to obtain 100% light output in less than a second, whereas conventional germicidal lamps start at only 50% output and take several minutes to achieve 100% output.
The featured Care222 12W B1 module contains 4 highly efficient 222nm excimer lamps and a patented filter that eliminates dangerous longer wavelengths of more than 230nm in an easy to install housing.
