Atosa AUR72SD 72 inch Undercounter Refrigerator

Atosa AUR72SD 72" Undercounter Refrigerator — Three-Section Reach-In

The Atosa AUR72SD is a 72-inch three-section undercounter refrigerator built for high-volume restaurants, banquet kitchens, and full-service bars that need maximum cold storage in a slide-under-counter footprint. At 72-5/8" wide and 32-1/2" tall on its pre-installed casters, it tucks neatly under standard 36" prep counters and bar tops while delivering 18.2 cubic feet of usable cold storage across three independent door sections — the largest single undercounter unit in the AUR lineup. Rear-mounted self-contained refrigeration, R290 hydrocarbon refrigerant, an electronic temperature controller, and a full stainless steel cabinet make this a true commercial workhorse rated for daily back-of-house abuse.

This is point-of-use refrigeration with workflow built in. The three-door configuration keeps cold air losses small — bartenders and cooks open only the section they need, leaving the other two-thirds of the cabinet sealed and cold. Instead of a line cook walking to the walk-in for backup garnish, dairy, or pre-portioned protein every ticket, those ingredients live at the station. That single change recovers minutes per ticket during a rush and keeps your line moving. Order today — most units ship within one business day from our warehouse with free freight to the lower 48.

Built for the Tight Spots Other Units Can't Reach

The AUR72SD is a workhorse for bartenders, baristas, and chefs who need maximum cold storage exactly where the work happens:

• High-volume restaurant prep lines — full-shift backup capacity for proteins, dairy, sauces, and prepped ingredients across three independent zones
• Bar wells and back bars — milk, mixers, juice, and garnish at arm's reach with three-door capacity for high-volume nightlife and weekend service
• Banquet kitchens and catering operations — bulk cold storage for plated service prep, dessert holding, and event mise en place
• Three-zone organization — dedicate one section each to proteins, dairy, and produce to streamline workflow and inventory rotation
• Allergen-dedicated storage — three-section design lets you isolate gluten-free, vegan, or shellfish-free ingredients in their own zone
• Catering kitchens and prep rooms — pair with a stainless worktable to build a full-line cold prep station

Refrigeration System

The 1/5 HP rear-mounted compressor uses R290 hydrocarbon refrigerant — the EPA-recognized natural alternative to legacy HFCs, with high heat-absorption capacity that pulls cabinet temperature back down faster after each door open. The compressor is sized to keep all three sections at temperature simultaneously even with frequent door cycles during a rush. Translation for the operator: shorter compressor cycles, lower amp draw, and a unit that actually holds 38°F during the 7:00 PM rush instead of drifting into the food-safety danger zone.

The electronic temperature controller mounts on the cabinet exterior and is factory-set to maintain 35°F to 38°F. Real-time interior temperature reads on the display, and adjustments take seconds — no dial-and-guess. Automatic condensate evaporation routes defrost water to a pan above the compressor where motor heat evaporates it off, so no floor drain is required and no drip tray needs emptying.

Stainless Construction Built to Last

Stainless steel interior and exterior resist the heat, humidity, acid spills, and commercial degreasers that destroy plastic-lined residential units. A galvanized steel back panel adds structural rigidity where appearance does not matter. Foamed-in-place high-density polyurethane insulation locks in the cold and keeps the cabinet's thermal barrier intact in 90°F kitchen ambient conditions. All three self-closing solid hinged doors have stay-open features for hands-free loading and magnetic gaskets that create tight, airtight seals on every close — and the doors are field-reversible, so the same unit drops into a left- or right-hinge installation without ordering a different SKU.

Three adjustable interior shelves (one per section) reconfigure for tall bottles, half-pans, or sheet pans depending on the station's needs. Pre-installed 2" casters make the unit easy to roll out for cleaning the rear condenser coil — the single most important maintenance task on any commercial refrigerator. Field-installable drawer cartridges are available as an accessory if you need to convert any of the three sections into drawer bases.

Specifications

Installation and Clearance

The AUR72SD is rear-vented, so the compressor breathes from the back of the cabinet. Maintain at least 2" of clearance behind the unit and 1" on each side. Pushing the unit flush against a wall traps compressor heat, drives up energy use, shortens compressor life, and voids the warranty. Plug into any standard 115v outlet on a dedicated 15-amp circuit — no special electrical work required. Place on a level surface; the casters provide both mobility and the airflow gap underneath the cabinet. At over 250 pounds empty and well over 400 pounds when fully loaded with product, confirm your floor is rated for the point load before placing the unit, especially in older buildings or upper-floor installations.

Why Operators Choose Atosa

Atosa builds commercial refrigeration that holds spec at a price point independent operators can actually afford. The AUR72SD competes head-to-head with units twice the price on the metrics that matter — recovery time, build quality, and component reliability — without the premium tied to a brand name. Browse the full Atosa refrigerator lineup for matching prep tables, two-door reach-ins, and worktops that share the same controller, gasket, and shelving systems.

Frequently Asked Questions

Does this unit need a floor drain?

No. Automatic condensate evaporation handles defrost water using residual compressor heat. No plumbing connection required.

What is the temperature range?

35°F to 38°F, controlled by an exterior-mounted electronic thermostat. The unit holds food-safe refrigeration temperatures in standard kitchen ambient conditions.

How much clearance does the AUR72SD need?

Minimum 2" at the rear and 1" on each side. The compressor is rear-mounted and rear-vented; restricted airflow causes overheating, voids warranty, and shortens compressor life.

Are the doors reversible?

Yes. The AUR72SD ships with field-reversible doors on all three sections, so the same unit can be installed with left- or right-hand hinges depending on your bar or kitchen layout. Door reversal is performed in the field at install time.

What plug and outlet does it use?

NEMA 5-15P standard 3-prong plug, 115v / 60Hz / 1-phase, 2.8 amps. Plugs into any standard commercial outlet on a dedicated 15-amp circuit.

What refrigerant is used?

R290 hydrocarbon — the EPA-recognized natural refrigerant that has replaced legacy HFC refrigerants as the commercial standard for energy efficiency and environmental compliance.

How often should the condenser coil be cleaned?

At least monthly. Pull the unit out on its casters, vacuum the rear coil, and brush off any flour, dust, or grease. A clean condenser is the single highest-ROI maintenance task on the unit and the difference between a 3-year and a 12-year compressor lifespan.

Is the AUR72SD NSF certified?

Yes — cETLus listed for electrical safety and ETL-Sanitation listed (NSF compliant) for food contact. Passes commercial health inspection in all 50 states.

Can the AUR72SD be converted to a drawer unit?

Yes. Field-installable drawer cartridges are available as an optional accessory and convert any of the three sections of the standard solid-door cabinet into drawer bases for prep stations that need pan-style access.

What warranty comes with the AUR72SD?

Two years parts and labor, five years on the compressor. Extended warranty coverage up to five years is available as an optional add-on.
