Manitowoc IDT1500AP 1688 lb Indigo NXT Correctional Modular Ice Machine Head, Air-Cooled, Stainless Panels, Dice Cubes

The Manitowoc IDT1500AP is the correctional configuration of the Indigo NXT 48 in. air-cooled head, built for prisons, jails, and secure institutional foodservice where every exterior panel has to resist tampering. It makes the same ice as the standard machine, up to 1,688 lb of dice cubes per 24 hours at 70°F air and 50°F water and 1,350 lb at the 90°F rating point, from an air-cooled, self-contained condenser that needs no condenser plumbing. What changes is the shell: stainless steel panels with stainless louvers over the condenser face and tamper-proof fasteners that only open with special bits controlled by staff. It is a head only, sized to the 48 in. D-970 storage bin sold separately, and facilities without a hardened-equipment requirement can specify the standard IDT1500A and skip the correctional premium. Installation matches the standard head: a 208-230V single-phase circuit with three-phase optional, a 3/8 in. FPT water inlet, a 1/2 in. drain, and 8 in. of top and side clearance with 5 in. at the back.

Icon-Based Touch Screen with Programmable Ice Production

Every function runs through the icon-based easyTouch display, so whoever closes the kitchen can read operating status, start a cleaning mode, or check an alert without hunting for a manual; the interface offers 13 language options and keeps a date and time stamp with automatic reminder and alert icons. Programmable ice production is the money feature: schedule the machine off during peak electrical rates, cap it by daily production volume, or shift the work to night programming so the bin is full before the morning crew clocks in. One touch calls up asset information, and the controller automatically detects accessories as you add them, so upgrades register without a service visit.

Easy-Access Front Door with Removable Water-Path Components

Cleaning happens through an easy-access front door panel rather than a service panel you unscrew and set aside. The water trough, distribution tube, curtain, and sensing probes all remove from the food zone, so a deep clean is a fast, complete job instead of a reach-around compromise, and selected components are made with AlphaSan antimicrobial material that works between cleanings. An optional LuminIce II virus and bacteria inhibitor controls viruses, bacteria, mold, and yeast inside the food zone, with a sanitation icon on the display reporting its operational status. For routine care you can go hands-off entirely: the iAuCS accessory schedules and performs cleaning cycles automatically, Arctic Pure water filters strip sediment and chlorine down to 0.5 microns ahead of the machine, and an external scoop holder keeps the scoop off the bin rim.

Acoustical Ice Sensing Probe with 24 Hour Intelligent Diagnostics

Manitowoc's patented acoustical ice sensing probe reads the harvest acoustically rather than by simple contact, which keeps cycles reliable in challenging water conditions that confuse conventional sensors. Active Sense software works in conjunction with that probe, adjusting so every harvest lands consistently as room temperature and water quality drift across the day, anywhere in the machine's 40°F to 110°F ambient and 40°F to 90°F water operating limits. Intelligent diagnostics watch the machine around the clock and surface preventative maintenance and diagnostic feedback right on the display, so a service tech arrives already knowing what the machine has reported instead of starting the diagnosis from zero.

All-Stainless Correctional Exterior with Tamper-Proof Fasteners

In place of the standard shell, the correctional package panels the machine in stainless steel, with stainless louvers over the air-cooled condenser face. Tamper-proof screws in two different head designs secure the ice machine front panel and the back cover, and both require a special removal bit that ships only in the startup package, so panels stay closed to anyone who has not been issued the tool. Underneath, the refrigeration system is unchanged Indigo NXT: R410A refrigerant, a CFC-free formulation that lowers global warming potential by 48 percent, moving 23,000 BTU/hr of average heat rejection (27,000 BTU/hr at peak) on a 208-230V connection with minimum circuit ampacity of 18.5 amps at 1 phase, 13.4 amps at 3 phase. That combination of hardened exterior and standard internals means parts and service follow the same path as every other Indigo NXT machine in the fleet.
