Abstract
A water conditioning device for conditioning the cold water supply to a beverage vending machine. The device uses a spirally twisted strip of corrosion and lime scale inhibiting copper-nickel alloy contained within a cylindrical casing through which the cold water is delivered. The spiral strip churns the water for more complete contact of the water with the strip surfaces as the water flows through the casing.
