In an age of global travel, pure water that is free of microorganisms is a major concern. With that in mind, Indianapolis Jet Center of Whitestown, Ind., has become the exclusive provider of the IJC-2 ultraviolet water disinfection system from the American Ultraviolet Company. The 28-volt system, about the size of a paper towel tube, fits neatly in any existing aircraft potable water system and contains a UV lamp that emits 254-nanometer radiation. The radiation attacks the DNA and RNA of microscopic pathogens such as E.Coli and salmonella, rendering them sterile and therefore harmless.
