Manitowoc K00450 LuminIce II Growth Inhibitor Kit for Indigo i-300 to i-1200 and QuietQube i-680C to i-1070C Ice Machines, UV Foodzone Sanitation

The Manitowoc K00450 is the field-installed LuminIce II growth inhibitor kit for Indigo i-300 to i-1200 ice machines and QuietQube i-680C to i-1070C models, built for operators fighting yeast, mold, and slime in a foodzone that never seems to stay clean between scheduled cleanings. The device mounts inside the machine and runs 24 hours a day whether ice is being made or not, passing foodzone air over a 254 nm UVC germicidal light and a 185 nm UVV light that together create Cold Oxygen Plasma, and independent lab testing showed noticeably cleaner foodzones after 2-1/2 months of use. Reduced slime buildup also speeds the regularly scheduled cleaning process, so each cleaning takes less labor and less machine downtime. This kit is specific to the Indigo generation; Indigo NXT machines take the K00464 or K00465 kit instead, NEO U-Series undercounters take the K00519, and the K00474 wire harness converts this kit to work with the appropriate Indigo NXT model if you upgrade the machine later. There is no separate power hookup or plumbing to run; the device mounts inside the machine and draws its electricity directly from the ice machine.

Dual UVC and UVV Germicidal Lights Create Cold Oxygen Plasma

Air from behind the evaporator passes a germicidal class 254 nm UVC light and is sterilized, then a 185 nm UVV light acts on the oxygen and water vapor in the air stream to create photo plasma. Cold Oxygen Plasma is a gas ionized by UVV light containing ions, free electrons, hydroxyl radicals, and ozone, each highly reactive with the microorganisms it encounters, and this active air recirculates continually within the foodzone to inhibit the growth of viruses, bacteria, and fungi.

Independent Lab Testing Confirms Reduced Yeast and Bacteria

An independent testing lab tracked average interior surface yeast counts and aerobic bacteria plate counts from installation through ten weeks, and machines running LuminIce II held visibly lower counts than machines without it. Foodservice operations often sit in challenging environments where preventing yeast, mold, and other microorganism contamination is difficult, and because the device defends the foodzone around the clock, protection continues overnight and through slow periods when the machine is not making ice.

Internal Mounting Powered Directly by the Ice Machine

The device is compact at 2.55 in. wide by 3.27 in. deep by 4.32 in. tall and mounts inside the Indigo cabinet, wired to the machine rather than to a wall outlet, so it adds nothing to the install footprint and nothing to the outlet count behind the machine. Because it treats the air stream inside the foodzone, it works with the ice machine you already own instead of replacing it, and the K00474 wire harness carries the same device forward to an Indigo NXT machine.

One Annual UV Bulb Change and No Chemicals to Maintain

There are no chemicals to add or maintain; the only recommended upkeep is a simple UV bulb change once a year to keep effectiveness at its peak. The bulb measures 0.75 in. in diameter by 4.125 in. long and carries a shelf life of three years from its date of manufacture, so spares keep. Use replacement bulb K00454 for Indigo machines built after July 1, 2015; the K00425 bulb serves only first-generation LuminIce devices on earlier Indigo units.
