Dallas, TX-based SandenVendo America has annouced a new line of vending machines that use hydrocarbon refrigeration systems, its first for the North American market, according to hydrocarbons21. The new glass- front vending machines and stack-style vending machines run on R290 instead of using CO2 as the other vending machine refrigeration systems do. The R290 is safe and abundant CEO and President of SandenVendo America, Mike Weisser, is quoted as saying. It has zero ozone depleting potential and a global warming potential (GWP) less than 4, the article cites. The availability of the hydrocarbon refrigeration systems allows the vending machines to meet Canadian and U.S. UL standards including exceeding U.S. Department of Energy and Environmental Protection Agency ENERGY STAR requirements.
