Water vending machine
Polela Concepts, of Penticton, British Columbia, released a new line of water vending machines for installation through store windows, walls or kiosks. The units will be marketed under the brand name of Liquid Action. The machines have a custom designed and manufactured control board for specific water-related functions. The units carry out all functions on a single control board to eliminate potential problems. Another inherent design problem in many machines occurs when 110 volts enter the machine cabinet.
