Korea-based Chung Ho Nais introduces a first in the world market—a reverse osmosis water purifier with Ice Maker, the “Ice Combo.?? Company president Hwang Jong Dae developed and marketed the purifier. It combines ice making and water purifying into one unit that allows the customer to have hot water, ice and ambient water with ice all year round. The patented icemaker applies the freezing point-lowering principle that states pure water freezes at 0°C degree while impure water freezes at lower temperatures.
