Brand Overview: Hoshizaki and Kold-Draft
Hoshizaki and Kold-Draft are the two leading commercial ice machine suppliers in the United States, offering high-quality, efficient ice machines. Despite a similar portfolio in the ice-making industry, they differ remarkably as commercial refrigeration equipment manufacturers.
Hoshizaki
Hoshizaki is a global leader in commercial refrigeration solutions with reach-ins, refrigerated merchandisers, prep tables, and, of course, ice machines. Established in 1947 in Japan, Hoshizaki opened a factory in Griffin, Georgia, in 2001 and acquired JACKSON WWS to expand its reach işn the American market. Hoshizaki is known for building durable machines that can last for years, even under commercial conditions, ranging from fast-food chains to hospitals.
Hoshizaki’s ice machine lineup is broad, ranging from compact undercounter units to massive modular systems that produce over 2,000 pounds of ice per day. Hoshizaki ice machines produce crescent ice machines, flake ice units, cubelet makers, and specialty models for specific industries.
Kold-Draft
Kold-Draft is a U.S.-based manufacturer of commercial ice machines which specializ almost exclusively in cube ice. The company was established in 1920, relocated to Erie, Pennsylvania, in 1926, and produced domestic pumps. Dedicated to constant innovation and technology, Kold-Draft introduced the first automatic ice machine with upside-down horizontal evaporators.
Focusing on cube ice for drinks, the Kold-Draft perfected cubelets and created crystal-clear, hard, slow-melting cubes that bartenders love. So, Kold Draft ice machines became a favorite for any serious cocktail bar in New York, Chicago, or San Francisco, and you’ll likely spot a Kold-Draft unit behind the bar.
Ice Types and Ice Quality Comparison
Hoshizaki and Kold-Draft ice maker machines are known for their durability and ice quality. When choosing a commercial ice maker, it is important to compare ice types and quality across the two brands.
Ice Types Produced By Hoshizaki
Hoshizaki offers a wide array of ice shapes tailored for various applications in restaurants, bars, supermarkets, and hotels:
- Crescent Ice: The signature shape produced by Hoshizaki ice makers features a “half-moon” design that prevents clumping and enables excellent liquid displacement in sodas, soft drinks, and iced tea.
- Cubelet (Nugget-style): The “chewable” ice widely used in healthcare and quick-service restaurants
- Flake Ice: Ideal for seafood displays, salad bars, and slushies.
- Square/Gourmet Cubes: Specialized options include spheres, 1″ x 1″ (2.54 cm x 2.54 cm), and 2″ x 2″ (5.08 cm x 5.08 cm) ice cubes for higher-end service.
Ice Types Produced by Kold-Draft
Kold-Draft doesn’t make flake ice, cubelet ice, or specialty shapes. Their ice machines produce only large and cocktail cubes, primarily intended for beverages, and the company is entirely committed to perfecting cube production.
- Full Cube Ice: Measuring 1.25 x 1.25 inches (3.17 cm x 3.17 cm), square ice cubes are ideal for spirits and cocktails. The freezing process creates exceptionally clear ice with minimal air bubbles.
- Coctail Cubes: They feature a unique shape with a 1-inch width (2.54 cm) and a 1.25-inch height (3.17 cm), delivering premium, slow-melting ice for all types of beverages.
Ice Clarity, Density, and Melt Rate
Ice clarity, density, and melt rate are not just technical details related to production; they are a significant part of the customer experience, with enhanced taste, a better look, and pure content. Margaritas, whiskey, and some cocktails, such as the Old Fashioned, have higher alcohol content, which accelerates melting. Hard ice cubes slow down the process and prevent over-dilution. Additionally, soda, Coke, and other beverages need slow-melting ice to prevent a watery taste.
The melt rate is directly affected by the clarity and density of the ice used to chill beverages. Kold-Draft cubes are denser than standard ice. This means they have a lower surface-area-to-volume ratio and melt significantly more slowly. Additionally, Kold-Draft’s “upside-down” freezing process ensures zero cloudiness and maximum clarity, which is vital for premium spirits.
Hoshizaki uses Advanced CleanCycle24 technology to reduce impurities and mineral buildup on evaporators, thereby increasing ice clarity. Hoshizaki IM series ice machines use horizontal ice plates that slowly produce ice upside down, producing hard, clear ice with no bubbles or cavities.
Build Quality and Engineering Design
Build quality and engineering design determine how ice machines perform under pressure, how long they last, and how easily they can be serviced. Hoshizaki and Kold-Draft follow two different engineering philosophies: Hoshizaki focuses on durability and continuous high-volume production, while Kold-Draft prioritizes exceptional cube clarity and premium beverage presentation.
Hoshizaki Engineering Approach
Hoshizaki designs its ice machines around mechanical durability and long-term operational reliability. Most models feature 304-grade stainless steel evaporators and exterior housings, improving corrosion resistance and sanitation while protecting critical components from heavy daily use. Because the evaporator performs the freezing process, using stainless steel significantly reduces the risk of pitting, flaking, or performance degradation over time.
Hoshizaki systems are engineered for continuous high-volume production environments. Many modular KMEdge™ crescent cubers use dual-sided evaporator plates, allowing the machine to freeze ice simultaneously on both sides and maintain consistent output during peak service periods. Depending on the model, production capacity can reach up to 1,653 lb (749.8 kg) of ice per day, making these machines well-suited for large restaurants, hotels, and institutional kitchens.
The brand offers one of the widest product portfolios in the industry, producing up to eight different ice types, including crescent, cubelet, flake, and specialty gourmet formats. This versatility allows operators to match ice production with beverage service, food display, or healthcare applications while maintaining stable output hour after hour.
Kold-Draft Engineering Approach
Kold-Draft takes a different engineering approach, focusing primarily on ice-cube precision and beverage quality rather than on maximum production speed. Its systems are designed to produce large, crystal-clear cubes that melt slowly and maintain drink structure in premium cocktail programs.
Instead of continuous sheet freezing, Kold-Draft machines spray water over refrigerated cube plates in a carefully controlled pattern. This process gradually freezes purified layers of ice while pushing minerals and impurities away from the forming cube. The result is a dense, clear cube with minimal air pockets and a slower dilution rate, which is highly valued in high-end bars and craft beverage environments.
Because this purification process takes longer per freezing cycle, Kold-Draft machines typically operate at lower production speeds compared with high-volume systems. The brand’s largest models still deliver up to about 1,000 lb (453.6 kg) of ice per day, balancing premium cube quality with reliable commercial output.
Reliability and Operational Performance
Hoshizaki is one of the most reliable brands in the commercial refrigeration industry. These ice machines are expected to have a lifespan of 10–15 years with regular cleaning and maintenance. Hence, they feature panels that make essential components easy to access and removable air filters. Most Hoshizaki ice makers feature CycleSaver designs that reduce operational time by half while maintaining the same production capacity.
Kold-Draft machines deliver unrivaled shape consistency. Every cube is a perfect 1.25-inch (3.17 cm) square. However, they have historically been more sensitive to environmental factors and to constant use, with more complex construction, and require expert maintenance.
Maintenance, Cleaning, and Serviceability
Maintenance and cleaning extend the operational lifetime of commercial ice makers. Hence, both brands provide a guideline for cleaning and maintenance. Hoshizaki recommends a detailed maintenance schedule including:
- Daily: Cleaning the ice scoop
- Bi-weekly: Washing and cleaning air filters
- Monthly: Inspection of external water filters and replacement if needed
- Yearly: Inspection and cleaning of water supply inlet, condenser, and water hoses
Kold-Kraft recommends maintenance twice a year, but it requires more attention and includes additional details, as outlined in the Kold-Kraft ice maker maintenance manual. This cleaning cycle includes rinsing and cleaning of the cabinet, water line, and all other accessible parts and components.
Most commercial refrigeration technicians are familiar with Hoshizaki equipment. The brand’s market presence makes it easy to find qualified service in most metro areas. Parts availability is strong, and the machines use relatively standard components. But Kold-Draft’s service network is more specialized. While technicians are available in major markets, smaller cities may have limited availability, and you may experience longer service-call wait times than with Hoshizaki. Therefore, please check service and parts availability in your area or consult your ice machine lessee.
Energy Efficiency and Operating Costs
Ice machines run continuously in commercial settings; therefore, energy efficiency and operational costs are significant concerns. Many Hoshizaki models are Energy Star certified for their low energy consumption, such as 4 kWh per 100 lbs (45.35 kg), while Kold-Draft focuses more on ice quality than efficiency ratings, with 6 kWh per 100 lbs (45.35 kg) of ice production.
Hoshizaki generally uses less water per pound. Hoshizaki water consumption typically ranges from 13-22 gallons (49.21-83.27 lt) per 100 pounds (45.35 kg) of ice, and Kold-Draft ice maker water consumption is around 15-26 gallons (56.78 lt to 98.42 lt) per 100 lbs (45.35 kg) of ice, depending on the ice type and production capacity.
Ice Production Capacity and Scalability
Hoshizaki offers a wide range of daily production capacities, from small-scale 50 lb units to industrial workhorses with 2617 lb (1187.05 kg) daily production. Kold-Draft’s range is narrower, with most models rated at 200-800 pounds (90.71-362.87 kg) per day. Their largest units achieve capacities up to 1000 lbs per day, but the primary focus spot is mid-range volume typical of bars and upscale restaurants.
For growing operations, Kold-Draft expansion typically means adding complete units rather than scaling modularly. This works well for bar programs, but it can become space-intensive during rapid growth. Hoshizaki offers scalable solutions, including dual-sided evaporators with much higher capacities, modular ice maker systems that scale up to 2,000+ pounds (907.18 kg), and twin-unit systems.
Pricing and Total Cost of Ownership
Hoshizaki ice makers typically range from $4,025 to $15,600 for standard bar and restaurant models, with specialty or high-capacity units priced higher. Kold-Draft machines are priced from $5,640 to $10,000+, with comparable production capacity.
Maintenance costs over five years favor Hoshizaki due to simpler cleaning requirements and broader service availability. Energy and water expenses tilt toward Hoshizaki for high-volume operations. A restaurant producing 500 pounds (226.79 kg) daily could see $200- $400 in annual utility savings, which is meaningful over the machine’s lifespan.
ROI calculation depends entirely on your business model. A craft cocktail bar charging $14+ per drink can justify Kold-Draft’s premium because ice quality directly impacts the product. But a casual-dining restaurant serving fountain drinks sees a quicker return on that same investment by choosing a Hoshizaki unit.
Target Use Cases and Industry Fit
Due to design and engineering differences, Hoshizaki and Kold-Draft ice machines are the best choices for healthcare, schools, cafeterias, and high-end restaurants.
Hoshizaki Use Cases
Hoshizaki offers a wide range of commercial ice machines that produce 8 ice types, including nugget, crescent, cube, flake, and sphere. They are ideal for high-volume restaurants that require reliable output during lunch and dinner rushes. Their service and parts availability keep them among the leading choices among the foodservice and bar applications.
Healthcare and institutional environments commonly prefer Hoshizaki because it offers a variety of ice types to meet different patient needs. In addition, their durability under continuous use presents a continuous supply of ice.
Schools and cafeterias choose Hoshizaki for its efficient, reliable performance and high-volume production capacity. Educational institutions need equipment that survives years of heavy use with minimal issues.
Kold-Draft Use Cases
Craft cocktail bars and upscale lounges represent Kold-Draft’s core market. When your cocktail program is a key differentiator for your business, ice quality becomes a competitive advantage. Therefore, bartenders prefer Kold-Draft cubes for slow melting and crystal-clear ice.
High-end restaurants with premium beverage programs find value in Kold-Draft for their bar service, even if they use different ice in the kitchen. Whiskey bars and spirit-focused concepts benefit most from slow-melting, clear ice. These establishments often promote their ice choice to ensure proper serving temperatures and dilution.
How Hoshizaki and Kold-Draft Fit Into a Commercial Refrigeration System?
Ice machines don’t operate in isolation, but they’re components of larger refrigeration systems. Both brands produce ice that drops into separate storage bins. Bin sizing matters as much as machine capacity. A 400-pound machine paired with a 200-pound bin creates bottlenecks during busy periods. You need an ice bin larger than your hourly production capacity to hold excess ice during slow periods and catch up on peak-time service.
Integration with dispensers is another consideration for streamlining your ice handling. Crowded settings, self-service restaurants, and bars simplify the ice service through ice dispensers. Hoshizaki’s ice types work with most standard dispensing equipment. Kold-Draft’s larger cube format requires appropriately sized chutes and dispensing mechanisms to prevent jamming.
Display equipment compatibility is critical for seafood restaurants and buffet operations. Hoshizaki’s flake ice machines integrate seamlessly with cold display cases. Kold-Draft’s focus on cube production means you’ll need separate equipment for display applications.
Consider electrical requirements, drainage, and ventilation during the purchase planning process.
