Why a Reach-In Refrigerator Is the Backbone of Your Kitchen
The commercial reach-in refrigerator is the workhorse of every back of house. It holds the prep ingredients, sauces, dairy, and finished product that your line needs within arm's reach, and it runs 24 hours a day, 365 days a year. Because it never stops working, the reach-in is also one of the most common pieces of equipment to buy wrong: undersize it and product ends up on the floor; oversize it and you are paying to cool empty space.
This guide walks through the specifications that actually matter: sections and cubic footage, door styles, temperature performance, refrigeration systems, materials, and electrical requirements. Full spec sheets for every major brand are on CookBidSpecs, and used reach-ins are widely available at restaurant equipment auctions.
Sizing: One, Two, or Three Sections
Reach-ins are sold by the number of sections, and each section is roughly 27 inches wide:
- One-section: about 27 inches wide, roughly 20 to 23 cubic feet.
- Two-section: about 54 inches wide, roughly 40 to 50 cubic feet.
- Three-section: about 80 inches wide, 60 to 75 cubic feet.
Full-height units are typically 80 to 84 inches tall and 30 to 35 inches deep. A common rule of thumb is 4 to 6 cubic feet per seat in a full-service restaurant, adjusted for prep volume; if you also have a walk-in, the reach-in only needs to hold a day or two of product.
Door Styles: Solid, Glass, Hinged, and Sliding
- Solid doors are standard for back-of-house storage. They insulate best and are cheapest to run.
- Glass doors are for merchandising — grab-and-go cases, beverage coolers, and display units. They cost more to operate because of heat gain.
- Hinged doors swing open and are the most common. Make sure the swing direction works with your aisle layout.
- Sliding doors save aisle space and are common in deli and prep applications, but they are slightly less efficient and can be harder to seal over time.
Full-door models are easier to load, but half doors lose less cold air when opened, which is why bartenders and sandwich lines often prefer them.
Temperature and NSF Compliance
A true commercial refrigerator holds 33°F to 38°F, and an NSF 7 rated unit maintains safe temperatures even in a 100°F kitchen — the spec that separates commercial units from residential fridges. For frozen storage, a reach-in freezer should hold 0°F or below. Check the spec sheet for the compressor's operating envelope: a unit rated for 100°F ambient air will hold temperature on a July line; a residential-style unit will not.
Self-Contained vs Remote Refrigeration
- Self-contained units have the compressor built in. They plug in, move easily, and are the standard for most restaurants. The downside is that the compressor dumps heat into the kitchen and the unit needs airflow clearance around it.
- Remote systems put the compressor on the roof or outside. They are quieter, add no heat to the kitchen, and are more efficient, but installation cost is higher and they are typically specified for larger or multi-unit installations.
Most buyers choose self-contained, which is fine — just respect the clearance requirements in the spec sheet.
Air-Cooled vs Water-Cooled Condensers
Self-contained reach-ins are almost always air-cooled, so the condenser needs clean airflow; keep the coil dust-free and away from heat sources, or the compressor will fail early. Water-cooled units exist for tight spaces, but they use water and require a drain, so they are rare.
Undercounter vs Full-Height
Undercounter reach-ins (typically 27 to 48 inches wide and 32 to 36 inches high) fit beneath prep counters and are the standard for sandwich stations and bar coolers. They hold 5 to 10 cubic feet and are perfect for small, high-turnover items. Full-height units give you the most storage per square foot of floor space, and many kitchens use a combination of both.
Materials and Construction
- Stainless steel interiors and exteriors are the most durable and easiest to sanitize; they are standard on better units.
- Aluminum or galvanized steel is cheaper and lighter and fine for dry storage areas, but it dents and stains more easily.
- PVC-coated shelves resist rust.
- Door gaskets should be replaceable; a worn gasket is the most common cause of a reach-in that runs constantly.
Look for self-closing doors, cam-lift hinges that hold doors open for loading, and an interior light — small details that cost little and save frustration.
Brands to Know
True, Turbo Air, Beverage-Air, Delfield, and Hoshizaki are the names you will see most often on spec sheets. True and Turbo Air are known for durable self-contained units with good warranties; Beverage-Air and Delfield are common in storage and merchandising applications. All publish detailed spec sheets and show up regularly on the used market.
Electrical Requirements
Most one- and two-section reach-ins run on standard 115V/120V and plug into a dedicated 15- or 20-amp circuit. Larger three-section units and some specialty models require 208V or 230V, and some are available in three phase. Always confirm voltage and phase on the spec sheet before ordering. See the CookBidSpecs guide on commercial refrigeration electrical requirements for the full breakdown.
Energy Use
A reach-in runs around the clock, so efficiency matters: ENERGY STAR rated units, auto-defrost freezers, and good door seals reduce operating cost, and a unit packed against a wall or next to a fryer will burn far more electricity. Give it the clearance the manufacturer specifies.
New vs Used
A new reach-in is a reasonable investment, but the used market is deep: restaurant auctions regularly sell True, Turbo Air, and Beverage-Air reach-ins at a fraction of retail. Before bidding, find the model on CookBidSpecs and check dimensions, voltage, and cubic footage against your space. At preview, listen for the compressor, check the gaskets, and look for rust on the evaporator. A unit that holds temperature is worth the risk; one with a tired compressor is not.
Reach-In Buying Checklist
- Sections and cubic footage vs menu and seating
- Door style, swing direction, or sliding
- Temperature rating (33-38°F) and NSF 7 compliance
- Self-contained vs remote, air-cooled condenser
- Undercounter vs full-height placement
- Stainless construction and replaceable gaskets
- Voltage, phase, and amperage vs your outlets
- Clearance for airflow and door swing
- Spec sheet verification on CookBidSpecs
Get the size, temperature rating, and voltage right, and the brand choice becomes much less stressful. A reach-in that fits your space and holds temperature for a decade is a good buy at any price.
