Nonflammable alcohol vapor in CO2 (NAV-CO2) systems use carbon dioxide (CO2) as a propellant to dispense a 56% isopropyl alcohol solution in a stream of CO2 gas. The use of CO2 as a propellant serves to displace ambient oxygen and eliminate the risk of explosion.
CO2 is gas at room temperature, while liquid alcohol evaporates off of contact surfaces within minutes after application. Surfaces do not require wiping, reducing the spreading of pathogens on cloths. Alcohol and CO2 are inexpensive and readily available.
Environmental advantages include a viable alternative to oxidizing sanitizers such as bleach.
