Frequently asked questions
Common questions about NU-CALGON from 3G Electric.
What is the difference between the nickel-safe and non-nickel-safe Nu-Calgon ice machine cleaners?
Nu-Calgon ice machine cleaners are available in both nickel-safe and non-nickel-safe formulations. The nickel-safe versions, such as part 4287-08 (liquid, 1 gallon) and part 4209-07 (solid), are formulated to protect nickel-plated components during cleaning. The non-nickel-safe version, part 4207-47 (liquid, 8 oz), should not be used on nickel-plated components. Selection depends on the materials of construction in the ice machine's evaporator and water system. If the machine has nickel-plated surfaces, use a nickel-safe cleaner. If not, either type may be suitable, but always verify compatibility with the machine manufacturer's recommendations.
What viscosity grade are the Nu-Calgon refrigerant evacuation pump oils, and what container sizes are available?
Nu-Calgon refrigerant evacuation pump oils are supplied in ISO-46 viscosity grade with an SAE viscosity grade of 30.5. They are clear oils intended for lubricating and sealing vacuum pumps during refrigerant evacuation in HVAC/R systems. Container sizes include 1 pint (part 4383-34), 1 quart (part 4383-24), and 1 gallon (part 4383-07). The correct oil for a given vacuum pump is specified by the pump manufacturer; matching the ISO or SAE viscosity grade helps maintain proper sealing and efficient moisture removal during evacuation.
What is the Nu-Calgon hydronic flush solvent used for, and what size is it supplied in?
The Nu-Calgon hydronic flush solvent, part 4370-08, is a liquid from the System Cleaner series supplied in a 5-gallon pail. It is used to remove debris and contaminants from hydronic heating and cooling systems. The yellow fluid is designed for flushing closed-loop hydronic systems during maintenance or before commissioning. The 5-gallon pail size is typical for servicing larger hydronic systems or multiple smaller systems. It should be used according to the manufacturer's instructions for circulation time, temperature, and disposal.
What are the operating temperature limits for the Nu-Calgon corrosion inhibitor?
The Nu-Calgon corrosion inhibitor, part 4299-T8, is a pump protector supplied in a 10 oz container with a maximum operating temperature of 122°F. It is formulated to inhibit corrosion and scale buildup in industrial pumping systems. The 122°F limit should be observed to maintain product stability and performance. This product is intended for systems where the circulating fluid temperature does not exceed that limit. For higher-temperature applications, consult the manufacturer's technical data for alternative products.
Can Nu-Calgon ice machine cleaners be used in food service and industrial ice machines?
Nu-Calgon ice machine cleaners are formulated for commercial and industrial ice machine applications. The nickel-safe liquid cleaner (part 4287-08) and solid cleaner (part 4209-07) are suitable for use in food service and similar environments where nickel-plated components are present. The non-nickel-safe liquid cleaner (part 4207-47) is intended for machines without nickel-plated wetted parts. Always follow the machine manufacturer's cleaning instructions and rinse thoroughly after cleaning to avoid residual chemical contact with ice. These are service chemicals, not food additives, and should be stored and handled accordingly.
