Designed for operators who know that ice is critical to their 
business, the Indigo™ Series ice machine's preventative 
diagnostics continually monitor itself for reliable ice production. 
Improvements in cleanability and programmability make your 
ice machine easy to own and less expensive to operate.
• Space-Saving Design – Up to 1,860 lbs. (845 kgs.) daily ice  
production and only 48" (121.92 cm) wide.
• Intelligent Diagnostics – provide 24 hour preventative  
maintenance and diagnostic feedback for trouble free 
operation. 
• Acoustical Ice Sensing Probe – for reliable operation in  
challenging water conditions. 
• EasyRead Display – communicates operating status,  
cleaning reminders, and asset information through a blue 
illuminated display. 
• Programmable Ice Production – by On/Off Time, Ice  
Volume or Bin Level (with accessory bin level control) further 
improves energy efficiency and savings. 
• Easy to Clean Foodzone – Hinged front door swings out  
for easy access. Removable water-trough, distribution tube, 
curtain, and sensing probes for fast and efficient cleaning. 
Select components made with AlphaSan® antimicrobial.
• DuraTech™ Exterior – provides superior corrosion resistance.  
Stainless finish with innovative clear-coat resists fingerprints 
and dirt. 
• Available LuminIce™ Growth Inhibitor controls the growth  
of bacteria and yeast within the foodzone.
