Undercounter Ice Machine Guide
Essential undercounter ice makers for restaurants, bars, and commercial kitchens
Undercounter ice machines provide compact, efficient ice production for space-constrained commercial operations. These self-contained units fit beneath counters while producing various ice types for different applications. From air-cooled models for standard installations to water-cooled systems for specialized environments, this guide helps operators select the right undercounter ice machine for their specific needs.
Overview
Undercounter ice machines are compact refrigeration units designed to fit beneath standard countertops, providing convenient ice production and storage in limited spaces. These self-contained systems combine ice production, storage, and dispensing in a single unit, making them ideal for bars, restaurants, cafes, hospitals, and other commercial settings where ice is frequently needed but floor space is at a premium.
Popular commercial applications include:
- Bars and cocktail lounges - Quick access to ice for drink service
- Restaurants and cafes - Ice for beverages, food display, and customer service
- Hospitals and healthcare facilities - Clean, consistent ice for patient care
- Coffee shops and quick-service operations - Ice for cold drinks and smoothies
The machines produce various ice types including cube, nugget, and flake ice, with production rates from 50 to over 400 pounds per day. While professional installation is recommended for optimal performance and warranty coverage, knowledgeable operators can perform installation if they have experience with plumbing, electrical work, and refrigeration systems.
