My watch list  


Non-flammable Alcohol Vapor in Carbon Dioxide NAV-CO2 systems were developed in Japan in the 1990s to sanitize hospitals and ambulances. These systems were developed to respond to a need for a safe, effective, and environmentally sound way to sanitizing without the use of toxic or corrosive chemicals.


Theory of operation

NAV-CO2 systems use liquid CO2 as a propellant. NAV-CO2 systems combine Alcohol-based sanitizing solutions with a heated stream of CO2 liquid to create a vapor capable of penetrating small crevices and gaps. As CO2 and atomized Alcohol evaporate completely at room temperature, no residue remains. CO2 displaces oxygen, eliminating one of the elements needed to support combustion. Sanitizing chemicals such as quaternary ammonium can be added to alcohol based sanitizers to extend the killing time on surfaces. NAV-CO2 systems are used to sanitize contact surfaces where individuals may become infected. Hand washing and sanitizing surfaces with Alcohol-based solutions are effective method s for the prevention of nosocomial infection.


Hospitals, Ambulances, Nursing Homes, Public Waiting Areas and Food Processing Plants are likely places where disease causing bacteria and viruses are known to colonize. NAV-CO2 eliminates the use and disposal of toxic chemicals such as bleach and other commercial products.
