To choose the right commercial ice machine for a Phoenix restaurant, consider four key factors: ice type (full cube, half cube, nugget, or flake), production capacity (1.5 lbs per customer per day plus 20–30% for Arizona heat), cooling method (air-cooled, water-cooled, or remote condenser), and brand reliability in extreme heat. Hoshizaki, Manitowoc, and Scotsman are the top-performing brands in Arizona's 115°F+ climate.
Choosing the right commercial ice machine is one of the most important equipment decisions a restaurant owner can make. The wrong choice can lead to constant ice shortages, high energy bills, and frequent repairs. This guide will help you understand the key factors to consider when selecting a commercial ice machine for your Phoenix-area restaurant.
Understanding Ice Machine Types — There are three main types of commercial ice machines: modular (or head units) that sit on top of a separate ice bin, self-contained units that include a built-in storage bin, and undercounter units designed to fit beneath a standard counter. Modular units produce the most ice and are ideal for high-volume restaurants and bars. Self-contained units are a good middle ground for moderate-volume operations. Undercounter units are best for small bars, cafes, and food trucks.
Industry Data: Air-cooled ice machines lose 15–20% of rated production capacity when ambient temperatures exceed 100°F, a critical consideration for Phoenix restaurants.— ASHRAE Handbook — Refrigeration
Choosing the Right Ice Type — Different businesses need different types of ice. Full cube ice is the most versatile and melts slowly, making it ideal for drinks. Half cube ice is smaller and more economical, commonly used in fast-casual restaurants and self-serve beverage stations. Nugget ice (also called chewable ice) is popular in healthcare facilities and specialty beverage shops. Flake ice is used primarily for food displays and seafood counters. Consider what your customers expect and what your menu requires.
Sizing Your Ice Machine — The most common mistake restaurant owners make is buying an ice machine that is too small. A general rule of thumb is 1.5 pounds of ice per customer per day for a full-service restaurant, and 1 pound per customer for a fast-casual operation. However, in Phoenix, you should add 20 to 30 percent to these estimates because Arizona's extreme heat increases ice consumption significantly. Also factor in ice used for food prep, display, and any bar operations.
Industry Data: Water-cooled ice machines use 100–200 gallons of water per day, costing approximately $0.57–$1.14 per day at Phoenix water rates of $5.72 per 1,000 gallons.— City of Phoenix Water Services Rate Schedule
Air-Cooled vs. Water-Cooled — Most commercial ice machines are air-cooled, meaning they use ambient air to cool the condenser. In Phoenix, where ambient temperatures regularly exceed 110 degrees, air-cooled machines work harder and produce less ice. Water-cooled machines use water instead of air to cool the condenser, making them more efficient in hot climates. However, they use significantly more water, which is an important consideration in Arizona's desert environment. A third option is remote condensers, which move the heat-producing condenser unit outside or to the roof, keeping the kitchen cooler.
Top Brands for Arizona — Based on our experience servicing commercial ice machines across Maricopa County, the brands that perform best in Arizona's extreme climate include Hoshizaki (known for exceptional build quality and reliability), Manitowoc (excellent ice production capacity and energy efficiency), and Scotsman (innovative designs with strong performance in hot environments). All three brands offer models specifically designed for high-ambient-temperature environments.
Industry Data: ENERGY STAR-certified ice machines use up to 25% less energy and 25% less water than standard models, saving $200–$500 per year.— ENERGY STAR Commercial Ice Machine Guide
Installation Considerations — Where you place your ice machine matters enormously in Arizona. The machine should be in a well-ventilated area, away from ovens, grills, and other heat sources. Ensure there is adequate clearance around the condenser for airflow. The water supply should include a quality filtration system to address Arizona's hard water, which causes mineral scale buildup. Proper installation by a qualified technician is essential for optimal performance and warranty compliance.
