Atosa Model Number Guide

Decode any Atosa model number: what the prefixes mean, how the generations work, and what replaced the models Atosa retired.

Atosa updates its model numbers more often than most brands in foodservice: the same 60-inch prep table has carried three different model numbers since 2017. There is a good reason for the pace - Atosa keeps revising its equipment, with high-efficiency compressors, the shift to environmentally friendly R290 refrigerant, digital temperature controls, and design updates aimed at longer service life - and the model number is where that constant improvement shows up. This guide decodes the system: what the prefixes mean, how the generations work, what replaced the models Atosa retired, and what warranty applies, drawing on our own Atosa records maintained since 2016.

How Atosa Model Numbers Work

Every Atosa model number has two working parts: a prefix that tells you the product family, and a suffix that tells you the generation. MSF8307GR-NTCV breaks down to MSF (sandwich and salad prep table), 8307 (the specific unit in that family), GR (the 2019 generation), and NTCV (the current refresh of that same unit).

That structure is the key to the whole catalog. Atosa retires and reissues model numbers on its own schedule, but the numbering logic has stayed consistent for a decade - which means once you can read a prefix and a suffix, you can identify almost any Atosa unit, including ones that no longer appear in any current listing.

The Prefix Decoder

The Three Generations of Atosa Model Numbers

The bare era (through early 2019). Original models carried no suffix: MBF8005, MSF8307, MGF8401. If your unit's data plate shows a bare number, it was built in this era.

The GR era (spring 2019 onward). In one sweeping change between February and May 2019, nearly the entire refrigeration catalog re-issued with a GR suffix - same units, new codes. An L on the end (GRL) marks a left-hinged door version. Atosa has never published what GR stands for; in our records it simply marks the 2019 generation.

The NTCV era (late 2023 onward). Starting in August 2023, GR models began gaining NTCV twins - MSF8307GR-NTCV alongside MSF8307GR - with matching specifications. This rollout is still in progress, which is why you will often see both codes for what is functionally the same unit.

Why two model numbers show for one unit: during a transition, Atosa's regional warehouses keep shipping the earlier version until stock runs out, so both codes remain genuinely orderable - sometimes for a year or more. That is why we list both generations while both are available, and retire the old listing only once the earlier version is sold through everywhere.

One lineage tells the whole story. The 60-inch mega top prep table has been MSF8307 (through early 2019), MSF8307GR (May 2019), and MSF8307GR-NTCV (October 2023) - three numbers, one table.

1. Atosa Refrigeration

The core of the catalog: cold storage in every footprint a kitchen uses. Where a family replaced an older model line, the history is noted under that category.

Reach-In Refrigerators

The MBF family is Atosa's backbone, and it shows in the numbers: the MBF8005 of a decade ago is today's MBF8005GR, the same cabinet position in a lineup that has held remarkably steady. These are the one, two, and three door upright cabinets - solid doors for back-of-house storage, glass doors for visibility, half-door configurations for busy lines - running from compact single doors to 82-inch three-door boxes, with both bottom-mount and top-mount compressor options. Every kitchen build starts somewhere, and the Atosa reach-in refrigerators lineup is usually where.

Reach-In Freezers

The freezer side of the MBF family mirrors the refrigerators cabinet for cabinet: solid door bulk storage across the same 17-to-82-inch width range, glass door models for frozen display, and half-door setups that limit cold-air loss when the line hits the freezer all shift long. Frozen inventory is money in a box, and these are the workhorses that protect it. The current Atosa reach-in freezers carry the same GR-generation codes as their refrigerator twins.

Combination Refrigerator / Freezers

Dual-temperature cabinets that put a refrigerated section and a frozen section in a single footprint - the answer for kitchens where the floor plan cannot cover two separate boxes but the menu demands both temperatures. One compressor system, two climates, one delivery. Kitchens weighing this option can compare the current Atosa refrigerator freezer combos against buying separate cabinets.

Undercounter Refrigerators

Today's AUR series puts cold storage inside the workstation: solid door, glass door, and drawer units from 24 to 72 inches that keep ingredients at the station that uses them. The family is also the catalog's freshest naming scheme - the AUR models replaced the older MGF-prefixed undercounters one for one:

• MGF8401GR (and its left-hinge GRL version) became the AUR27SD
• MGF8415GR became the AUR27D2 drawer unit
• MGF8402GR became the AUR48SD
• MGF8404GR became the AUR72SD

If you are replacing an old MGF undercounter, its successor is waiting in the current Atosa undercounter refrigerators lineup.

Undercounter Freezers

The AUF series is the frozen half of the under-counter story: solid door cabinets and a drawer model that put fries, proteins, and backup stock beneath the work surface at fry stations, dessert stations, and cramped prep corners. Like its refrigerator twin, the line succeeded older MGF numbers:

• MGF8405GRL became the AUF27SD
• MGF36FGR became the AUF36SD
• MGF8407GR became the AUF60SD

The full range of current Atosa undercounter freezers runs from a slim 24-inch cabinet to a 60-inch two-door.

Worktop Refrigerators

The AWR series adds a reinforced work surface on top of undercounter refrigeration, so one footprint serves as both prep counter and cold storage - a different product from a standard undercounter, built for cutting boards and countertop work happening directly overhead. These replaced the MGF worktop numbers:

• MGF8408GR became the AWR27SD
• MGF8423GR became the AWR27D2 drawer unit
• MGF8409GR became the AWR48SD
• MGF8410GR became the AWR60SD

Compare surfaces and widths across the current Atosa worktop refrigerators.

Worktop Freezers

The AWF series brings the same work-surface-on-top concept to frozen storage, and it is actually the larger of the two worktop families. It likewise succeeded MGF-era numbers:

• MGF8412GR became the AWF27SD
• MGF8428GR became the AWF27D2 drawer unit
• MGF8413GR became the AWF48SD
• MGF8414GR became the AWF60SD

Stations that prep over frozen product can size up the current Atosa worktop freezers from 27 to 60 inches.

Chef Bases

With the undercounters and worktops moved to their own series, MGF now means one thing: chef bases. These are the reinforced-top drawer units built to carry a griddle or charbroiler directly above cold storage, so the protein headed for the heat is one drawer-pull away. The current family comes in both refrigerator and freezer versions - the freezer chef base being a genuine rarity in the industry - and the one-piece stainless tops are rated for countertop cooking equipment. See what fits under your line among the current Atosa chef bases.

Blast Chillers

Rapid-chill cabinets that pull cooked food through the temperature danger zone fast enough to satisfy HACCP cooling requirements - the food-safety workhorse for volume batch cooking, catering, and cook-chill programs. This is one of the newer corners of the Atosa catalog and a category where the technology does a very specific job no standard refrigerator can. Operations moving into batch production can review the current Atosa blast chillers.

2. Atosa Prep Tables

Refrigerated prep is where Atosa's renaming habit runs hottest: two families, both revised repeatedly, both central to any make line. If your kitchen assembles sandwiches, salads, or pizzas to order, one of these tables is the station everything else revolves around.

Sandwich & Salad Prep Tables

MSF is the most heavily revised family in the catalog and the source of this guide's showcase example - three model numbers for the same 60-inch table since 2017. The current lineup runs from a compact 17-inch one-door unit to 72-inch three-door mega tops holding up to thirty sixth-size pans, split between standard tops and mega tops that pack roughly half again more pan capacity into the same width. Anyone building a sandwich, salad, or deli line can compare layouts across the current Atosa sandwich and salad prep tables.

Pizza Prep Tables

The MPF family takes the prep-table concept and rebuilds it for pizza: wider rails sized for one-third pans instead of sixth pans, deeper work surfaces for stretching dough, and refrigerated bases with room for dough boxes and toppings at volume. The family has carried its prefix since 2016, currently topping out around a 93-inch three-door spread. Pizzerias sizing a make line can start with the current Atosa pizza prep refrigerators.

3. Atosa Bar & Beverage Equipment

The families that run the bar, each with one job and a stable prefix to match. Bar refrigeration is bought by the run rather than the piece, so these categories are usually shopped together - the cooler, the bottle box, and the draft box sharing the same stretch of underbar.

Back Bar Coolers

The MBB family covers the whole run behind the bar: 23-inch corner units, two-door workhorses at 48, 59, and 69 inches, and roughly 90-inch three-door cabinets, in solid, glass, and sliding glass doors - a G in the number (MBB59G) means glass. In 2020 Atosa added the SBB stainless back bar series alongside it for bars that want the underbar in stainless. Bar builds of any size can map their run against the current Atosa back bar coolers.

Bottle Coolers

The MBC series is the classic slide-top box: bottles and cans stacked cold at the bartender's hip, opened and shut a hundred times a night without a door swing to worry about. It is a simple product with a simple job, which is exactly why the family has stayed compact and stable. Dive bars and high-volume beer accounts alike can size up the current Atosa bottle coolers.

Beer Dispensers

Direct-draw draft boxes that hold kegs cold directly beneath the taps, from single-keg units on up - the all-in-one route to draft service without building a remote glycol system. For bars adding or expanding draft lines, the current Atosa beer dispensers pair the keg storage and the tower in one cabinet.

Glass Chillers & Frosters

Dedicated freezers with one job: frosted mugs and chilled glasses at serving temperature, ready the moment the pour happens. A frosted glass is a small touch that customers notice every single time, and this small Atosa family exists entirely for that moment. Bars that want the detail handled can look over the current Atosa glass chillers and frosters.

4. Atosa Merchandising & Display

Front-of-house equipment where the product sells itself: refrigerated display, frozen display, and the hot cases that complete the counter. These are the categories where lighting and glass matter as much as temperature, because the case does the selling while the staff does everything else. 

Glass Door Merchandiser Refrigerators

The MCF family - lit, customer-facing coolers for grab-and-go fronts, convenience zones, and beverage walls - has carried the same prefix since 2016, making it one of the most stable corners of the catalog. One and two door uprights with the lighting and glass real estate that sell what is inside them. Stores and grab-and-go operations can compare the current Atosa glass door merchandiser refrigerators.

Glass Door Merchandiser Freezers

The frozen version of the merchandiser concept: glass door display freezers for ice cream, frozen novelties, and frozen grab-and-go, where the product needs to be seen to sell. Same merchandising logic as the refrigerated MCF line, held at freezer temperature. Frozen programs can review the current Atosa merchandiser freezers.

Countertop Glass Door Refrigerators

Compact display coolers built for counters and checkout zones - the impulse-purchase real estate where a cold drink sells itself while the customer waits to pay. Small footprint, full merchandising effect. Cafes and quick-serve counters can find the right fit among the current Atosa countertop glass door refrigerators.

Open Air Merchandisers

Air-curtain display coolers with no doors at all: customers reach straight in, which is the entire point. Nothing moves grab-and-go product faster than removing the door between the customer and the sandwich. These trade some efficiency for maximum speed of service, which is a trade busy locations happily make. See the current Atosa open air merchandisers.

Refrigerated Deli Display Cases

Service cases for delis, butchers, and prepared-food counters: curved and straight glass fronts, staff-side access, and the display lighting that makes the case itself the storefront. This is equipment customers stare into every day, so presentation is the product. Counters being built or refreshed can browse the current Atosa deli display cases.

Bakery Display Cases

Dry and refrigerated cases purpose-built for pastries, cakes, and desserts - dry heat-free display for breads and croissants, refrigerated display for cream cakes and anything that needs holding temperature while it tempts. Bakeries and cafes can weigh dry versus refrigerated among the current Atosa bakery cases.

Heated Display Warmers & Cases

The hot side of front-of-house display: heated cases that hold and merchandise ready-to-eat food at safe serving temperature - rotisserie programs, hot grab-and-go, fried chicken counters. The same display-sells logic as the refrigerated cases, at the other end of the thermometer. Hot-food programs can review the current Atosa heated display cases.

5. Atosa Ice Machines & Ice Equipment

The youngest corner of the catalog, named in the mid-2020s: machine heads, self-contained makers, dispensers, and the storage bins beneath them. Ice is also where Atosa's warranty terms differ from the rest of the line, so check the warranty section below before comparing models. 

Air Cooled Ice Machines

The newest major naming scheme in the catalog: the YRM (modular) and YRS (self-contained) codes appeared in the mid-2020s, making ice the youngest corner of the Atosa system. Current machines make half cube ice at 350 to 1,000 pounds per day across 22-inch and 30-inch widths, and every unit ships with a 3M water filtration system included - an accessory many operators otherwise buy separately. Anyone sizing ice production for a bar or kitchen can start with the current Atosa air cooled ice machines.

Undercounter Ice Machines

The YRU series: compact self-contained makers that produce and store ice in one cabinet that fits beneath the counter - the right scale for bars, cafes, and waitstations that need steady ice without a modular head-and-bin tower. See the current Atosa undercounter ice machines.

Ice & Water Dispensers

Combination units that dispense both ice and water hands-free - the standard answer for self-service beverage stations, healthcare floors, and anywhere sanitation rules favor touch-free ice over a scoop and bin. Facilities weighing dispensers against bins can compare the current Atosa ice and water dispensers.

Ice Bins

The BYR storage bins are the bottom half of every modular ice setup, pairing with YRM machine heads to set total storage capacity. This family carries its own transition note: the earlier YR800 bin became today's BYR0400. When matching a bin to a head, capacity and width both matter - see the current Atosa ice bins.

6. Atosa Specialty & Supplies

The categories that round out the brand: institutional coolers, countertop cold storage, and the consumables that keep equipment alive. None of them headline a kitchen build, but each solves a problem the bigger equipment leaves behind, and they follow the same family logic as everything else in the catalog. 

School Milk Coolers

The MKC family: drop-front coolers sized for milk cartons in school cafeterias and institutional food service, built for the daily rhythm of load-in, service line, and lock-up. A specialized family with a stable prefix and a very specific customer. Districts and institutions can review the current Atosa milk coolers.

Refrigerated Condiment Holders

Countertop refrigerated rails that keep toppings and condiments at safe temperature right at the point of use - pizza stations, taco lines, ice cream counters, anywhere a row of cold pans needs to live on the counter without giving up the space a full prep table demands. It is one of those categories nobody plans around until the health inspector asks how the toppings are being held. The current Atosa refrigerated condiment holders cover the standard countertop sizes.

Equipment Cleaners & Degreasers

Atosa also offers the consumables that keep its equipment running: cleaners, descalers, and degreasers formulated for foodservice equipment, plus drain maintenance products. Keeping condenser coils and drain lines clean is the single cheapest way to extend equipment life, and the current Atosa equipment cleaners and Atosa drain cleaners and openers cover the routine.

Buying During a Model Transition

Atosa's rolling transitions create a practical question: if a listing shows the GR code and another shows GR-NTCV, which should you buy? In almost every case it does not matter. The specifications match, the price is typically identical, and because warranty coverage runs by ship date rather than by model code, a unit of either generation shipping today carries the same current warranty terms.

The one thing worth doing is noting which code actually arrives on your invoice - that is the number you will need for registration, service calls, and parts lookups. And if a seller quotes you the older code at a meaningful discount near the end of a transition, that is usually genuine clearance of regional stock, not a lesser product.

Discontinued Families

Chest freezers (MWF). Atosa no longer makes chest freezers; the MWF family, sold from at least 2017, has been retired. For frozen storage today the closest Atosa equivalents are undercounter freezers for line stations and reach-in freezers for bulk capacity. As Atosa retires other families over time, they will move to this section with their replacements noted.

Current Atosa Warranty Terms

Effective July 1, 2026, Atosa raised its standard refrigeration warranty. Terms apply by ship date - any unit shipping on or after that date carries the new coverage automatically:

Extended coverage of 5, 7, or 8 total years is available on refrigeration. Note that some older third-party pages still show the pre-2026 two-year terms - the figures above are current.

Model availability dates in this guide are estimates drawn from our own records, maintained since 2016. Atosa introduces and updates models on its own schedule, and previous versions sometimes remain available until sold out.
