Manitowoc JCT1500-251 Vertical Discharge Remote Condenser for Indigo NXT iT1500N and iT1900N Ice Machine Heads, Air-Cooled, R410A System

The Manitowoc JCT1500-251 is the vertical discharge remote condenser for Indigo NXT iT1500N and iT1900N remote-ready ice machine heads, built for operators who want condenser heat and fan noise moved out of the kitchen instead of dumped into it. Sited on a roof or in a utility area, indoors or outdoors, it keeps the system making ice through ambient swings from -20°F to 120°F, and because the heat of rejection leaves the building, the machine indoors runs in cooler air, which protects ice production through summer service and takes load off the air conditioning. This is one component of a matched remote system, not a complete machine: the ice machine, storage bin, condenser, and line set are all ordered separately, and the spec sheet pairs this condenser only with the iT1500N and iT1900N machines. The smaller iT1200N head pairs with the JCT1200 instead. If you cannot run a refrigerant line to a remote location, a self-contained air-cooled machine is the better format. Plan the line run before ordering: combined horizontal and vertical distance tops out at 100 ft with 35 ft of rise or 15 ft of drop, and power reaches the condenser through the ice machine, so a separate condenser circuit is optional rather than required.

Vertical Discharge Airflow Rated Down to 20 Below Zero

The condenser discharges its airflow straight up, so it mounts in a convenient location indoors or outdoors and holds its operating range from -20°F to 120°F through winter cold snaps and rooftop summer heat alike. Moving the air-cooled condenser away from the ice machine improves efficiency and ice production, conserving energy, because the machine no longer works against its own rejected heat. The 69 lb housing measures 29.50 in. wide by 27.94 in. deep and stands 34.00 in. or 38.00 in. tall on its optional leg heights, with up to 20 in. of bottom clearance allowed for raised mounting.

Pre-Charged Refrigerant Circuit With Quick-Connect Fittings

All components of the remote system arrive pre-charged with refrigerant and carry quick-connect fittings, so installation does not require field brazing or a full field charge. The factory charge covers line runs up to 50 ft; longer runs take additional refrigerant at the time of installation. The condenser serves R410A refrigerant systems, matching the iT1500N and iT1900N machines it is designed around.

100 Ft Line Runs With 35 Ft Rise and 15 Ft Drop

Refrigerant lines can run up to 100 ft of combined horizontal and vertical distance between the condenser and the ice machine, with a maximum vertical rise of 35 ft above the machine and a maximum drop of 15 ft below it, which covers most rooftop and mechanical room placements. Other horizontal and vertical combinations are calculated from the remote condenser installation instructions, so the line path gets verified on paper before anyone lifts a condenser onto a roof.

Powered From the Ice Machine on a Single Feed

Electrical power to the condenser is intended to be supplied from the ice machine itself, drawing 1.0 amps on its 208-230V, 60 Hz, 1 phase service, so a standard install adds no dedicated condenser circuit; a separate power source can be used when the site requires it. HACR-type circuit breakers can be used in place of fuses, and the sheet publishes minimum circuit ampacity and maximum fuse size for each matching machine so the shared feed is sized correctly from the start.

Matched Line Sets in 20, 35, and 50 Ft Lengths

Manitowoc's interconnecting refrigerant lines for this pairing come in 20, 35, and 50 ft lengths (RL-20-R-410A, RL-35-R-410A, RL-50-R-410A), each pre-charged and fitted with quick-connect couplings, and each ordered separately so the run matches the building instead of coiling excess line on the roof. A coated coil version, the JCT1500Q, is offered for salt spray environments within 5 miles of the coast.
