Lime Scale Formation,Sediment, Objectionable Taste or Odor, Slime Growths,Rough Freezing Surface Cloudy or Milky Ice, or Dirty Cooling Coils
Lime Scale Formation:
Lime scale is a common problem in ice machines. Even though the water is not heated, the hardness minerals tend to concentrate in the water and precipitate out on the freezing surfaces. The ice tends to stick to the scale and this jams the machine. Years of experience with ice making equipment have proven that the best way to solve the problem and reduce service calls is to prevent this scale formation by treating the water with the food-grade polyphosphate, Micromet. Before the treatment is started, however the machine should be cleaned, and possibly sanitized.
Removing Scale Deposits:
Liquid Ice Machine Cleaner
Nickel-Safe Ice Machine Cleaner
Controlling Slime Growths:
IMS-II
Preventing Scale Deposits:
Micromet is a slowly soluble food-grade polyphosphate that keeps scale-forming minerals in solution and prevents formation of scale on the freezing surface of ice machines. There are two types of Micromet that may be used: Micromet Crystals which dissolve at the rate of about 25% per month and require monthly recharging, or 6R Micromet which dissolves about 3-5% per month and lasts up to 6 months between service calls. It is NSF-listed and it is USDA-accepted.
Prevent Scale, Removes Sediment and Removes Objectionable Tastes and Odors:
The complete treatment program for commercial ice makers, coffee urns and brewers, beverage makers and other water-using equipment such as humidifiers, steamers and residential refrigerator ice makers.
Micro-Plus Treatment Systems are available in a variety of size capacities, from the Micro-Plus 2, which can be used on equipment using up to 12 1/2 gallons of water or 25 lbs. of ice per day, to the Micro-Plus 16 for treating up to 100 gallons of water or 1000 lbs. of ice per day. Micro-Plus systems are designed and manufactured to eliminate or control the three primary water-related problems...lime scale, silt and sediment (down to 20 microns), and objectionable tastes and odors. When properly sized, Micro-Plus will last for six months.
All units are constructed of NSF approved polypropylene, and are tapped on each end with 1/4" FPT. Installer may then utilize flare fittings, compression fitting or the male plug for quick disconnect fittings.
Prevent Lime Scale, Sediment or Objectionable Tastes and Odor:
The NP Series is a complete, multi-functional treatment system, consisting of two different size housings, the NP24DD and the NP48DD, and a family of "problem solving" cartridges.
The NP Series has been developed in order to permit the service technician or user to customize their installation to address a specific water-related problem or problems. There are cartridges for the control of scale, for the removal of silt and sediment and for the removal of objectionable tastes and odors And, the cartridges are available in sizes to fit both NP Housings.
The product line is also augmented by accessory items. Two different bracket assemblies are available to permit the installation in series of two or three NP Housings. By using the bracket assemblies, the installation can be customized to correct two or three water-related problems. Also, a gauge package is available for use where it is necessary to continually monitor the pressure of the water serving the ice machine, beverage machine, etc. This is often a recommended procedure when filtering water with a high level of silt or sediment.
Scale Control:
The NP246R Micromet Cartridge contains sufficient 6R Micromet to provide scale control on ice machines making up to 900 lbs. of ice per day or other equipment using up to 100 gallons of water per day. The NP486R Micromet Cartridge contains double the amount of 6R Micromet and can treat up to 1800 lbs. of ice or 200 gallons of water per day. When properly sized, treatment will last for six months.
NP246R Micromet Cartridge - 4705-87
NP486R Micromet Cartridge - 4715-87
Sediment Removal:
Use either the NP24S or the NP48S polypropylene sediment cartridges. Both are rated at 20 microns, and provide long service life. Exceptional dirt-retaining capability. Low pressure drop ratings...0.5 psi at 5.0 gpm flow. Manufactured from FDA-Approved materials.
NP24S Cartridge - 4702-87
NP48S Cartridge - 4712-87
Scale Control & Taste/Odor Removal Cartridges:
Both of these NP Series Cartridges are highly-specialized elements, bringing the capabilities of 6R Micromet and activated carbon together in one element. Designed for use in either the NP24DD or the NP48DD Housings, they provide for the control of scale as well as the removal of objectionable tastes and odors and filtration to 10 microns. The NP24PC can handle up to 65 gallons of water (600 lbs. of ice) per day, while the NP48PC can handle 135 gallons (1200 lbs.) per day.
NP24PC Micromet/Carbon Cartridge - 4706-87
NP48PC Micromet/Carbon Cartridge - 4716-87
Objectionable Tastes and Odors:
Use either the NP24C or the NP48C carbon block cartridges. Both are rated at 10 microns and provide greater absorption capacity than typical granulated activated carbon. Removes VOC's, TOC's and cysts (giardia lamblia). Manufactured from FDA-Approved materials.
NP24C Cartridge - 4701-87
NP48C Cartridge - 4711-87
Other Problems
Rough Freezing Surface
Food Grade Silicone:
Often times, particularly in older machines, the freezing surface will not be as smooth as it was at the time of original installation. Use of Food Grade Silicone will provide a non-stick surface and help prevent binding and sticking of the ice.

Dirty Cooling Coils
Aerosol CalClean:
Buildup of greasy dirt on refrigeration cooling coils and on air-cooled condensers impedes air flow and reduces heat transfer. This condition can put a severe strain on both the equipment and the pocketbook. Protect equipment and maintain efficiency by using CalClean to remove dirt and greasy film from coils and filters.
20 oz. aerosol - 4081-75
Aerosol Nu-Blast:
A "no-rinse required" condenser coil cleaner in a convenient aerosol package. Double action of high pressure blast and solvent cleaning restores design efficiency of condenser coils...quickly and easily. It has a pleasant odor and is non-flammable and non-conductive.
18 oz. aerosol - 4290-75
Slime Growths
Nu-Cal UV Series:
After years of testing and refinement, an ultraviolet light method of purifying water and eliminating slime growths in ice machines is now available. Disinfection is achieved by exposing the makeup water to ultra-violet light at a controlled water flow rate and then filtering with carbon. The UV Series is disposable, affordable and will last for twelve months. There are two units available: NP-UV4 which will handle a maximum flow of 0.5 gpm and the NP-UV6 which will handle 1.0 gpm. Both are equipped with 1/8" FPT connections. The power supply is regulated by a custom designed 110V ballast.
