Atosa Ice Machines

Atosa commercial ice machines are the value-focused workhorse we built our entire ice category around. Serious daily production, real 2-year parts-and-labor warranty (one full year above the tier-one industry default), NSF-certified sanitation, and free freight to a commercial dock on every unit. Atosa fits the independent restaurant, bar, hotel, and hospitality operator who wants dependable ice production without paying premium-brand markup.

This collection covers the full Atosa lineup: undercounter units from 140 to 283 lb/day, commercial heads from 450 to 800 lb/day, modular heads from 350 to 800 lb/day, hotel and beverage dispensers, and every matched storage bin. Below the models you'll find sizing math, installation requirements, maintenance schedule, and the pricing framework we walk on the phone every day.

Atosa Ice Machine Lineup at a Glance

Atosa builds across five form factors. Pick the form factor first, then size to your daily demand.

Undercounter (self-contained, plug-and-play)

• YRU0140A-161 - 140 lb/day, integrated bin, fits under most 34-36" counters. Built for cafe service, espresso bars, juice bars, and small QSR.
• YR140-AP-161 - 142 lb/day undercounter, alternate configuration in the same capacity class.
• YR280-AP-161 - 283 lb/day undercounter, the strongest single-cabinet unit that still fits below a 34" counter line.
• YRU0280A-161 - 280 lb/day undercounter, the current-generation 200-lb-class unit.

Commercial Heads (production with paired bin)

• YR450-AP-161 - 450 lb/day commercial ice maker.
• YR800-AP-261 - 800 lb/day commercial ice maker.

Modular Heads (paired with a separate bin)

• YRS0350A-161 - 350 lb/day, 22" modular half-dice head.
• YRM0450A-161 - 450 lb/day, 30" modular head.
• YRS0450A-161 - 450 lb/day, 22" modular head, narrower footprint.
• YRM0600A-261 - 600 lb/day, 30" modular head.
• YRS0600A-261 - 600 lb/day, 22" modular head.
• YRM0800A-261 - 800 lb/day, 30" modular head, the workhorse for the 1,000 lb-class build.

Hotel and Beverage Dispensers

• HD350-AP-161 - 350 lb/day hotel dispenser with 160 lb integrated storage, push-chute dispense, R290 refrigerant, variable-speed compressor. The Atosa flagship.
• YDS0350A-161 - 350 lb/day hotel dispenser, current-generation configuration.
• YR450S-AP-161 - 460 lb/day beverage dispenser head for higher-volume self-serve stations.

Storage Bins (pair with modular and commercial heads)

• BYR0300 - 300 lb storage bin.
• BYR0400 - 400 lb storage bin.
• CYR400P - 395 lb storage bin.
• CYR700P - 700 lb storage bin.

Any Atosa bin works with any Atosa ice head. Pick the bin sized to your peak two-hour draw, not to a specific head model.

Water Filtration

• 3M ICE120-S - high-flow carbonless filter system for Atosa ice machines.
• 3M HF20-S - replacement filter cartridge.

The Atosa Value Stack

Across every form factor, Atosa ships with the same core promises. This is why we recommend Atosa more than any other brand for independent restaurants and bars.

• Free freight to the continental US on every ice machine. Shipping a 400 lb modular head is expensive; Atosa builds the number into list price so you don't get surprised on the invoice.
• 2-year parts and labor warranty standard, plus a 5-year compressor warranty. Extended 3, 4, and 5-year coverage available at purchase. The industry default at tier-one brands is 1-year parts and labor - Atosa ships an extra year of labor coverage as the default, which is real money the first time a tech rolls a truck.
• NSF certified for food contact and ETL listed for electrical safety. Health inspectors and code officials sign these off without a second look.
• R290 refrigerant on the HD350 flagship and rolling into more of the lineup. R290 has a Global Warming Potential of 3 vs the legacy R404A at roughly 4,000, and runs at lower head pressure for longer compressor life.
• 30-50% below tier-one MSRP at equivalent capacity once you factor in free freight. That spread is why our entire ice category is built around Atosa.
• Financing is available through restaurant equipment financing - apply online for monthly-payment options across the full lineup.

Sizing Your Atosa Ice Machine

Undersizing is the single most common ice machine buying mistake. Running out of ice at 8 PM Friday costs more than the up-front difference between a 400 lb and a 600 lb head. Here's the working math.

Daily Demand by Operation Type

• Restaurant: 1.5 lbs per guest per day
• Bar: 3 lbs per bar seat per day
• Hotel: 5 lbs per occupied room per day
• Healthcare: 10 lbs per patient per day
• Catering: 1 lb per guest plus 50% buffer for outdoor or summer events

Always add a 20% buffer for hot weather, holiday rushes, and the real-world gap between lab rating and cook-line production.

Lab Rating vs Real Production

Spec sheets rate capacity at 70°F room air and 50°F incoming water. Add 10°F to either and capacity drops roughly 10%. A 350 lb/day machine in an 85°F cookline with 65°F water is honestly making 280-300 lbs/day. Size to your hottest day, not your average day.

Bin Sizing vs Production

Production is how fast the machine refills. Bin is how much ice is on hand at peak. A 350 lb/day machine with a 160 lb bin can serve 350 lbs of demand spread across the day, but it cannot serve a 200 lb burst at lunch open if the bin starts empty. Spec the bin to your peak two-hour draw, the production to your daily total.

Sizing Table by Business Type

The 200 lb Class: What It Actually Means

A "200 lb" ice machine produces 200 pounds of ice in a 24-hour period under lab conditions. That number is not the storage on the unit and it is not what the machine weighs - it is production capacity per day. Lab conditions assume 70°F room air and 50°F incoming water. In August on a real cook line at 95°F ambient with 70°F supply, the same machine lands 10-20% below rated.

The YR280-AP-161 is the Atosa pick for the 200 lb class. It's a 283 lb/day undercounter unit that beats the class straight out of the box - 80 lbs more daily production than you asked for, in a single cabinet you wheel in and plug into 115V. Free freight, 2-year parts/labor warranty plus 5-year compressor coverage. If your demand is lighter (under 140 lb/day) and counter space matters more, drop down to the YRU0140A-161.

The 350 lb Hotel Dispenser: HD350-AP-161

The HD350-AP-161 is the Atosa flagship and the unit we recommend more than any other for medium-volume operations that need clean, sanitary dispense.

Specifications

• Production: 350 lbs/day
• Storage: 160 lb integrated bin
• Dimensions: 23"W x 29.5"D x 70.9"H
• Refrigerant: R290 (GWP of 3, compared to R404A at roughly 4,000)
• Variable-speed compressor: ramps with demand for up to 40% energy savings
• Built-in 3M filtration with ICE120-S / ICE260-S cartridges
• Push-chute dispenser (no scoop, no cross-contamination)
• ETL listed and NSF certified
• Warranty: 2 years parts and labor + 5 years compressor standard; 3/4/5-year extended available

Why R290 Matters

R290 is a hydrocarbon refrigerant with a Global Warming Potential of 3. R404A, the legacy refrigerant still on a lot of older ice machines, has a GWP of roughly 4,000. Beyond the environmental case, R290 also runs at lower head pressure - less compressor stress and longer service life.

Why Variable Speed Matters

A single-speed compressor either runs full bore or it's off. A variable-speed compressor modulates with the bin level and ambient conditions. That's where the 40% energy claim comes from. It's also quieter at partial load, which matters when the unit sits in a guest-facing area like a hotel ice room or breakfast buffet.

Who the HD350 Fits

• Hotels with 60-150 rooms
• Self-serve beverage stations in QSR and fast-casual
• Healthcare and senior-living dispense lines
• Corporate cafeterias
• Any operation that wants to retire the scoop

Building the 1,000 lb Class Atosa Stack

Once daily demand crosses 600-800 lbs, you are in modular territory. The head produces ice and drops it; the bin stores it. They ship as two separate boxes and stack the head on the bin in your space. That's the only realistic way to hit 1,000 lb/day without giving up a small bedroom of floor space.

What 1,000 lb Actually Requires

• Modular head plus a separate storage bin (minimum 375 lb, often 500+)
• Dedicated 208V or 220V electrical circuit
• Floor load planning - a 200 lb head on a 100 lb bin full of 500 lbs of ice puts 800+ lbs on a small footprint
• Doorway and pathway clearance - a 30" wide head will not fit through an older 28" interior door; measure before ordering
• Liftgate delivery (you will not move this off a curb without one)

Atosa Configurations for the 1,000 lb Class

• YRM0800A-261 + CYR700P bin - 800 lb production head sized to a 700 lb bin. The practical 1,000 lb-class build.
• YR800-AP-261 - 800 lb/day commercial head as an alternative configuration.
• YRM0600A-261 + larger bin - 600 lb head with extended bin storage, good for operations with concentrated peak demand and lighter overall daily volume.
• For pure throughput where bin storage matters less than continuous production, stack two YRM0600A-261 heads on a wide bin (Atosa modular heads are designed to stack).

Who Needs 1,000 lbs/day

• Hotels above 200 rooms
• Stadiums, arenas, convention catering
• Large nightclubs and high-volume bars (150+ drinks/hour at peak)
• Seafood markets and grocery deli display
• Hospital and senior-living campuses
• Catering operations with multiple simultaneous events

Ice Types Atosa Machines Produce

Half-Dice Cube (the restaurant default)

Half-dice is the versatile default. Slow melt, good displacement in a glass, easy to scoop or dispense. Every Atosa modular head and every undercounter unit in this collection produces half-dice.

Hotel and Beverage Dispense

Push-chute dispense with no scoop and no contact between guest hand and ice. Required for any self-serve guest-facing application. Atosa fields the HD350-AP-161 hotel dispenser and the YR450S-AP-161 beverage dispenser head. See the hotel ice makers collection for the full dispense lineup.

Nugget, Gourmet, and Flake

Atosa does not currently field a nugget or flake unit. For nugget and gourmet clear cube we recommend the ITV Delta NG line. See the nugget ice machine collection for the full lineup.

Installation Requirements

Clearance

Air-cooled units need 6-12 inches of clearance on the back and sides for the condenser to breathe. Block that and you cook the compressor. Front-breathing models like the HD350 can sit flush to the wall on the sides and back.

Electrical

• 140 lb undercounter: 115V standard outlet
• 200-400 lb class: 115V dedicated circuit, 15-20A
• 500 lb+: 208V or 220V dedicated circuit
• Modular heads above 600 lb/day: always 208V or 220V

Always run a dedicated circuit. Sharing a circuit with a fryer or a reach-in is how breakers trip during service.

Water and Drain

• 1/4" cold-water supply line with shutoff valve
• Floor drain within 5 feet (gravity-fed is ideal; condensate pumps work but are a service item)
• Filter the supply line - the 3M ICE120-S plumbs in-line; the HF20-S is the replacement cartridge
• Hard water above 7 grains/gallon will scale the evaporator - consider a softener upstream

Path Planning

Measure every doorway, hallway, and corner from the loading dock to final position before ordering. A 30" wide head will not navigate an old 28" interior frame. For 1,000 lb-class builds, plan for liftgate delivery and a pallet jack on-site.

Placement to Avoid

Never put an ice machine next to a fryer, oven, range, or charbroiler. Radiant heat tanks the compressor and cuts capacity 20% or more. Six feet of separation minimum, more if possible.

Maintenance Schedule

Daily

• Wipe down exterior
• Keep the scoop in its holder, not in the bin
• Check bin level at open and close

Weekly

• Sanitize the bin interior
• Inspect the door gasket for cracking
• Check the condenser intake for dust buildup

Every 6 Months

• Replace the 3M filter cartridge
• Deep clean the evaporator and water system (factory cleaning solution, not bleach)
• Vacuum the condenser fins
• Inspect the water inlet valve

Hard Water Adjustments

If your supply is above 7 grains/gallon, move filter changes to every 3 months and the deep clean to every 4. Scale on the evaporator plate kills production capacity faster than any other failure mode.

Cost and Total Ownership

Purchase Price

Live pricing is on each product page above. Atosa undercounter units in the 140-283 lb/day range land in the $1,850-$3,300 range. Modular heads from 350-800 lb/day run $3,000-$4,500 before the bin. Storage bins add $900-$2,600 depending on capacity. Premium brands like Hoshizaki and Scotsman price 40-80% above equivalent Atosa units at the same capacity class.

If a tight budget is the primary constraint, we also offer Scotsman rentals and Hoshizaki rentals with rent-try-buy credit toward purchase.

Operating Cost

• Electricity scales with capacity and runtime; variable-speed compressors on newer models cut consumption meaningfully
• Water: roughly 18-25 gallons per 100 lbs of ice produced
• Filter cartridges every 6 months (more often above 7 grains/gallon hardness)
• Service is largely covered the first two years under Atosa's standard warranty

How to Choose Your Atosa Ice Machine in Five Steps

1. Calculate daily demand using the lbs-per-guest / seat / room formula plus a 20% buffer.
2. Pick form factor - undercounter up to 283 lb/day, commercial head 450-800 lb/day, modular 350 lb/day and up, hotel or beverage dispenser for guest-facing service.
3. Pick ice type - half-dice for most service, hotel dispense for self-serve, ITV nugget or ITV flake if your concept demands it.
4. Confirm infrastructure - electrical, water, drain, clearance, floor load, doorway path.
5. Add financing if needed, then call us to confirm fit before ordering.

Frequently Asked Questions About Atosa Ice Machines

Are Atosa ice machines good?

Yes. Atosa ice machines are widely used in commercial kitchens for reliable performance, value pricing, and consistent daily production. Atosa ships a 2-year parts and labor warranty plus a 5-year compressor warranty as the default, which is one full year of labor coverage above the tier-one industry default.

What is the best Atosa ice machine for a 100-seat restaurant?

A 100-seat restaurant doing two turns per day lands around 300 covers. At 1.5 lbs per cover plus a 20% buffer, that's 540 lbs/day of demand. The right Atosa pick is the YRM0600A-261 (600 lb modular) on a CYR700P (700 lb) bin. If you're tighter on space or budget, the YR450-AP-161 (450 lb commercial head) covers a single-turn operation comfortably.

How much ice does an Atosa 350 lb hotel dispenser produce?

The HD350-AP-161 is rated at 350 lbs/day under lab conditions (70°F air, 50°F water). In a typical hotel ice room running 75-80°F ambient with municipal water, expect 300-320 lbs/day real production. The 160 lb integrated bin is sized to absorb the typical guest dispense pattern.

What is the warranty on Atosa ice machines?

Standard is 2 years parts and labor, plus a 5-year compressor warranty. Extended coverage to 3, 4, and 5 years parts and labor is available at purchase. That's one full year of labor coverage above the tier-one industry default.

What is the difference between an Atosa modular and an undercounter ice machine?

Undercounter units (YRU0140A-161, YR140-AP-161, YR280-AP-161, YRU0280A-161) and the HD350-AP-161 hotel dispenser ship as one cabinet with the head and storage integrated. You plug it in and run it. Modular and commercial-head units (YRS, YRM, and YR series) ship as a head only; you choose and pair a separate storage bin (BYR0300, BYR0400, CYR400P, CYR700P). Modular gives flexibility on bin size and stackable heads for high-volume builds; an integrated cabinet installs faster and moves easier.

What water filtration does Atosa recommend?

Atosa machines run with 3M filtration. The 3M ICE120-S is the high-flow carbonless filter system that plumbs in-line before the machine, and the HF20-S is the replacement cartridge. Replace the cartridge every 6 months on standard water, every 3 months if your supply is above 7 grains/gallon hardness.

What types of ice do Atosa machines produce?

Half-dice cube is the standard across the Atosa modular and undercounter lineup. Atosa does not currently field nugget or flake units. For nugget, choose the ITV Delta NG line or Brema pebble nugget. For flake, choose the ITV Ice Queen series.

Where are Atosa ice machines used?

Independent restaurants, bars, hotels, healthcare, corporate cafeterias, catering, cafes, coffee shops, quick-serve chains, and any commercial foodservice operation that needs dependable ice production without paying premium-brand markup.

Do Atosa ice machines require maintenance?

Yes. Wipe the exterior and sanitize the bin weekly, vacuum the condenser monthly, and full deep-clean plus filter change every 6 months (3 months on hard water). Skipping the descaling cycle is the fastest way to lose 20% of your production capacity without an obvious warning.

Are Atosa ice machines easy to install?

Undercounter units plug into a standard 115V outlet, need a 1/4" cold-water line, and drain to a floor drain within 5 feet. Modular and commercial heads above 500 lb/day need a dedicated 208-230V circuit. Most installs take a licensed plumber and a licensed electrician for the code sign-off; the machine itself sets up in a few hours.

How much does an Atosa ice machine cost?

Undercounter units in the 140-283 lb/day range run $1,850-$3,300. Commercial heads and modular heads from 350-800 lb/day run $3,000-$4,500 before the bin. Storage bins add $900-$2,600. Free freight and warranty are already priced in.
