The compact EcO3Ice device uses a unique, synthetic diamond-based technology that continuously treats incoming water used by ice machines, killing bacteria, yeast and mold in the ice-making path from beginning to end. Reduces biofilm build-up, greatly extending required time between cleanings. With each cycle, EcO3Ice creates a small, safe but effective amount of pure ozone - nature’s own sanitizer - which continuously treats the machine interior, storage bin, dispenser and drains.
