Manitowoc RNP1100W 1158 lb Modular Nugget Ice Machine Head, Water-Cooled, 30 in. Wide, Bite-Size Chewable Nuggets

The Manitowoc RNP1100W is the water-cooled flagship of the RNP modular nugget line, built for high-volume operations whose machine rooms run too hot or too tight for air-cooled condensing. It produces up to 1158 lb of bite-size nugget ice per 24 hours at 70°F air and 50°F water and barely slows to 960 lb at 90°F, the highest output in the line, while drawing just 3.67 kWh per 100 lb of ice, the lowest energy rate of any RNP head. Condenser water consumption of 131 gal per 100 lb of ice is the cost of that performance, so sites without an economical condenser water source should weigh the air-cooled RNP1100A; both need a D-570 bin or dispenser below, and neither accepts the AuCS accessory. Plan for a 208-230V, 60 Hz circuit fused at 20 amps, separate 3/8 in. potable and condenser inlets, and 1/2 in. drains for each circuit.

Bite-Size Nuggets with an 85% Ice-to-Water Ratio

Nugget ice from the RNP1100W comes out in soft, chewable pieces averaging 3/8 in. to 1/2 in. in width and length. Its 85 percent ice-to-water ratio is one of the best in the category, so drinks get maximum cooling effect with minimal dilution, and the soft texture dispenses cleanly through beverage equipment. That combination is why nugget machines anchor soda fountains, smoothie programs, and cold-therapy service in the first place.

Rated Output at 70°F and 90°F Test Conditions

Manitowoc publishes production at both standard rating points: 1158 lb of nugget ice per 24 hours at 70°F air and 50°F water, and 960 lb at 90°F air and 70°F water. Plan around the second number, because it reflects a working kitchen in warm weather. At that hotter rating the machine uses 3.67 kWh of power and 12 gal of potable water per 100 lb of ice plus 131 gal of condenser water.

High-Load Maintenance-Free Bearings for Enhanced Reliability

The ice-making drive rides on high-load, maintenance-free bearings, reinforcing the wear point that works hardest in a machine that produces ice around the clock. A 1.5 HP compressor runs the R404A refrigeration circuit, and the evaporator is designed for maximum ice quality and operating life. Operating limits span 50°F to 100°F ambient and 45°F to 90°F incoming water, with inlet pressure between 20 and 70 psi.

Modular Head for D-Style Bins and Multiplex Dispensers

The RNP1100W is a machine head only: it makes ice but stores none. Set it on a D-570 storage bin and the stack stands 77.36 in. tall on 6 in. bin legs while holding 430 lb of nugget reserve, or mount it on a Multiplex beverage dispenser for direct soft-drink service. When dispensing, verify with the dispenser manufacturer that the correct agitator and deflector kit for nugget ice is included. Note that this model will not accept the AuCS accessory.

8 In. Top and Side Clearances with Rear-Intake Airflow

Manitowoc calls for 8 in. of clearance at the top and sides and 5 in. at the back, with cooling air entering at the rear and exhausting out the sides, so the head holds its rating inside an equipment lineup. Minimum circuit ampacity is 13.7 amps with a 20 amp maximum fuse, and HACR-type circuit breakers can be used in place of fuses.
