Nu-Calgon 4211-34 IMS-II Sanitizing Concentrate

For contractors maintaining commercial refrigeration and food service equipment, the Nu-Calgon 4211-34 IMS-II Sanitizing Concentrate is a field-proven ice machine sanitizer designed to eliminate bio-slime, mold, and odor-causing bacteria. This EPA-registered technical concentrate is nickel-safe and formulated specifically for hard, non-porous surfaces, making it compatible with major OEM brands like Follett, Manitowoc, and Scotsman. It serves as a critical final step in preventative maintenance for commercial ice makers, ice cream dispensers, and other food-contact equipment.

The quaternary ammonium formulation provides a 200 ppm active solution when mixed at a ratio of 1.6 fluid ounces per gallon of water. Its no-rinse application streamlines service calls, as technicians can simply flood the target area for 60 seconds and allow for air drying. Unlike harsh chlorine-based alternatives, this product will not damage nickel-plated evaporators or high-performance components. Each 16-ounce bottle provides enough concentrate for up to 10 typical maintenance cycles, ensuring an economical and professional-grade solution for preventing slime buildup and ensuring food safety compliance in high-volume kitchens and medical facilities.

• Strong quaternary sanitizer profile effective against bacteria, mold, and odors.
• Nickel-safe chemistry ensures compatibility with nickel-plated evaporators.
• EPA-registered and approved for all 50 states for food contact surfaces.
• Economical 1.6 oz/gallon dilution ratio maximizes technician yield per bottle.
• Efficient no-rinse formula reduces downtime during preventative maintenance.

Is Nu-Calgon IMS-II safe for nickel-plated ice machine evaporators?
Yes. This sanitizer is specifically nickel-safe and formulated not to pit or corrode sensitive evaporator plates when used at the recommended 200 ppm concentration.

Does IMS-II require rinsing after application?
No. When diluted at 1.6 oz per gallon of water, it is a no-rinse sanitizer. Once surfaces are thoroughly wetted and allowed to air dry for 60 seconds, the machine can be returned to service immediately.

What is the difference between an ice machine cleaner and IMS-II?
A cleaner or descaler (like Nu-Calgon Nickel-Safe Ice Machine Cleaner) removes mineral scale and calcium deposits. IMS-II is a sanitizer used after cleaning to kill microbial growth and prevent future slime build-up.
