Liquid Action, of Penticton, Canada, has released new coin management and bill acceptor systems in its line of self-serve purified water vending machines. The machines can be installed through store windows, walls or kiosks, and allows customers to refill their own water containers for huge savings vs. delivered water. The systems are especially designed for U.S., Canadian and Mexican markets. Operators are able to choose between three and four tube coin changers with a five-tube changer in the works.
