Crescent Cube Ice Machine: Why the Naixer TH-SE150 Is the 2026 Choice for Coffee Shops & Craft Bars
A barista pulls a shot of espresso. It is hot—around 90 degrees Celsius. They pour it over a glass of ice. If that ice is standard cube ice, something predictable happens. The cubes crack from thermal shock. Tiny fractures spread through them. Surface area increases. The ice begins to melt rapidly, and within a few minutes, a carefully crafted iced latte starts tasting thin and watery.
Now imagine the same pour over crescent ice. The hot espresso hits the curved surface of the half-moon cube and flows smoothly around it. The ice cools the coffee instantly but does not shatter. And because the cube is solid all the way through—no hollow center, no trapped air—it melts slowly enough that the drink still tastes rich and balanced twenty minutes later.
This is not a minor difference. For a coffee shop that sells hundreds of iced lattes a week, or a cocktail bar whose reputation rests on perfectly balanced Old Fashioneds and Negronis, the shape of the ice is the difference between a customer who orders a second round and one who does not come back. The Naixer TH-SE150 is a crescent cube ice machine purpose-built for exactly this distinction. It produces up to 150 pounds of crystal-clear, slow-melting crescent ice per day in a compact undercounter unit that fits beneath a standard bar. For a deeper understanding of why crescent ice has become the gold standard in specialty coffee, the guide on what type of ice do coffee shops use covers the science and the business case in detail.
In this guide, you will learn:
What the TH-SE150 Produces—and Why It Matters
The ice that comes out of a TH-SE150 is not just a different shape. It is a different product with a different performance profile, and that profile is optimized for beverages where temperature and dilution must be precisely controlled.
Each crescent cube measures 30 by 38 by 13 millimeters. The top is a smooth, curved half-moon. The bottom is flat. This geometry was not chosen for aesthetics. The curved surface channels liquid around the cube when poured, which is why hot espresso flows over crescent ice without splashing or shattering. The flat bottom and solid interior give the cube enough mass to resist melting far longer than a standard cube of equivalent size. The result is ice that cools rapidly on contact and then melts slowly over the life of the drink.
This dual behavior—fast initial cooling, slow ongoing dilution—is exactly what iced espresso drinks demand. A hot shot must be chilled immediately to lock in the volatile aromatics that give coffee its character. But once chilled, the drink should stay cold and undiluted while the customer sips it over fifteen or twenty minutes. Crescent ice achieves both goals in a way that standard cube ice, with its flat sides and often hollow centers, cannot match.
It also resists clumping in the storage bin. The rounded edges mean cubes do not lock together, so baristas scoop quickly and smoothly during a rush—no stabbing at a frozen brick of ice with a metal scoop. And because the curved surface channels liquid into the glass without splashing back, the bartender wastes less product during a busy service and the bar stays cleaner.
The TH-SE150 produces up to 150 pounds, or 70 kilograms, of this ice per day, with a 36-kilogram built-in storage bin. That is enough for approximately 400 to 550 iced drinks daily. For a busy downtown coffee shop or a craft cocktail bar with 80 seats, this capacity provides a comfortable buffer through the morning rush or the weekend dinner service without the machine struggling to keep up. And because the TH-SE150 is an undercounter unit—measuring 660 by 710 by 960 millimeters—it fits under a standard bar counter without demanding dedicated floor space. For venues where every square foot behind the bar is contested territory, this is a meaningful advantage. The guide on the best under counter ice machine compares the full range of compact commercial ice makers for operations with limited space.
Where the TH-SE150 Belongs
A crescent ice machine of this capacity is not for every operation. A high-volume nightclub that moves through thousands of pounds of ice a night in mixed drinks would be better served by a large modular cube machine. A fast-food restaurant that needs ice only for fountain sodas does not need the precision of crescent ice. But for venues where iced espresso drinks or spirit-forward cocktails are a core part of the menu, the TH-SE150 is the right machine.
The most natural home is the specialty coffee shop. These businesses live and die by the quality of their iced lattes, americanos, and cold brews. Their customers have been educated by years of coffee culture to notice when a drink tastes watery or off. Crescent ice solves the dilution problem at the source, ensuring that every iced drink that leaves the counter tastes the way the roaster and the barista intended. It also speeds up service. Because crescent ice does not clump, the barista spends less time wrestling with the ice bin and more time on the next ticket.
Craft cocktail bars are the second core market. A Negroni or an Old Fashioned is a drink that evolves in the glass over 20 or 30 minutes. The ice is not just a cooling agent; it is the ingredient that controls the rate at which the spirits open up and the dilution that softens their edges. Crescent ice, with its slow, predictable melt, gives the bartender far more control over that process than standard cubes. And because crescent ice pours without splashing, the bar stays cleaner and the bartender wastes less product during a busy service. The guide on the best ice machine for cocktail bar evaluates the full range of options for different bar profiles and volumes.
Luxury hotel lobbies and executive lounges represent a third application. These spaces serve a mix of coffee during the day and cocktails in the evening, often from the same bar. A single TH-SE150 can cover both dayparts with one ice type that performs beautifully in both applications. And because the machine is quiet—the compressor is mounted on vibration-dampening pads, and the front-venting design directs sound outward rather than into the wall cavity—it does not intrude on the atmosphere of a space where guests expect calm. For a broader perspective on how ice shapes influence drink quality across different settings, the article on what type of ice is best for a bar covers the decision-making framework.
The Engineering Behind the Investment
A commercial ice machine is expected to last 7 to 10 years with proper maintenance. The TH-SE150 is engineered to meet that expectation in demanding, customer-facing environments.
The entire ice-making zone—the evaporator, the water trough, the bin interior—is constructed from food-grade 304 stainless steel. This is a material that resists corrosion, cleans easily, and does not harbor bacteria in surface scratches the way plastic components do. For a machine that will spend a decade in a humid coffee shop or bar environment, the material choice matters.
The refrigeration system uses R290, a hydrocarbon refrigerant with a global warming potential of just 3. This complies with the EPA’s Technology Transition Rule that took effect on January 1, 2026, which requires all new self-contained ice machines with a capacity of 1,000 pounds or less to use low-GWP refrigerants. R290 is also more energy-efficient than the older refrigerants it replaces, which translates directly to lower electricity bills over the life of the machine.
Maintenance is designed to be straightforward. The One-Touch Cleaning function automates the descaling cycle—press a button, and the machine circulates the cleaning solution, drains, and rinses without disassembly. This removes the biggest barrier to consistent cleaning in a busy commercial environment, which is the time and complexity of doing it manually. For a complete step-by-step walkthrough of the cleaning process, the Naixer ice machine cleaning guide covers every stage from descaling to sanitizing.
Naixer backs the TH-SE150 with a 3-year comprehensive warranty on the entire machine, covering core systems and key components. The machine is manufactured in a 30,000-square-meter ISO9001-certified smart factory with more than 300 technical patents behind the engineering. Over 5,000 commercial clients worldwide, including KFC and Luckin Coffee, run Naixer equipment in demanding environments every day.
