The Astra 6 x 21 Walk-In Cooler No Floor CNF6X21 is a quick-ship commercial walk-in cooler box designed for restaurants, grocery stores, supermarkets, delis, bakeries, commissary kitchens, catering operations, prep kitchens, and foodservice businesses that need extended refrigerated storage for high-volume inventory and daily product movement.

With exterior dimensions of 6' 7"W x 21' 4"L x 7' 3"H, this model provides a long refrigerated storage footprint while keeping the cooler width practical for many back-room, receiving-area, and commercial kitchen layouts. The 6 x 21 size is especially useful for operators who need long shelving runs, organized inventory zones, and enough depth to manage frequent deliveries without moving into a wider walk-in cooler box.

This model is built as a no-floor walk-in cooler, which means it is designed for installations where the existing floor surface can be used instead of an insulated floor panel. For many indoor commercial environments, a no-floor configuration can support smoother access for carts, dollies, rolling racks, ingredient bins, beverage cases, and larger delivery loads. It can also help reduce the step-up entry often associated with floor-included walk-in boxes, depending on the installation site.

The Astra CNF6X21 uses 4" thick foamed-in-place polyurethane insulated panels with a modular cam-lock design engineered for commercial refrigeration applications. This construction supports efficient assembly, dependable cold storage performance, and flexible configuration for foodservice, grocery, retail, commissary, and commercial kitchen projects.

Best For

This 6 x 21 no-floor walk-in cooler is a strong fit for operations that need a long refrigerated storage area with room for structured inventory flow, including:

• Restaurants with high ingredient volume, bulk prep, and frequent supplier deliveries
• Grocery stores, supermarkets, and specialty food retailers storing produce, dairy, beverages, and packaged refrigerated goods
• Delis and sandwich shops organizing meats, cheeses, prepared foods, drinks, and bulk ingredients
• Bakeries and cafés needing extended storage for dairy, creams, fillings, toppings, and refrigerated prep items
• Commissary kitchens, catering companies, ghost kitchens, and prep kitchens managing larger production schedules
• Foodservice businesses replacing an older walk-in cooler or reducing dependence on multiple reach-in refrigerators

Why Choose the 6 x 21 No-Floor Model?

The 6 x 21 size is designed for commercial buyers who need a long, high-capacity cold storage layout that can support both daily inventory and delivery staging. Its extended footprint gives operators more room to divide the cooler into product zones, making it easier to separate produce, dairy, proteins, beverages, sauces, prepared foods, packaged goods, and incoming shipments.

For businesses that receive frequent deliveries, the extra length can make daily operations more organized. Staff can use the cooler not only for storage, but also as part of the receiving workflow, with dedicated space for newly delivered items, active prep inventory, and slower-moving stock. This helps improve stock rotation, reduce clutter, and make refrigerated products easier to find during busy service hours.

The 6-foot-wide format also makes this model useful for long storage rooms, receiving corridors, narrow back-room spaces, and commercial kitchen layouts where depth is available but width is limited. Instead of taking up a wide square footprint, the 6 x 21 layout uses length to create serious storage capacity while helping preserve working space around the cooler.

No-Floor Design for High-Traffic Storage Areas

A no-floor walk-in cooler is often selected for indoor installations on a suitable concrete or finished floor. Since this model does not include an insulated floor panel in the standard configuration, it can make access easier for staff moving carts, dollies, rolling racks, beverage cases, and heavier inventory in and out of the cooler throughout the day.

This can be especially helpful for businesses that use the cooler as part of a high-traffic prep, storage, or receiving area. When inventory is constantly moving in and out, easier roll-in access can help reduce friction and improve workflow.

Before ordering, the installation area should be reviewed for floor condition, levelness, drainage, ceiling height, door clearance, traffic flow, and delivery access. If your project requires an insulated floor, you can select the available floor option on the product page or consider a walk-in cooler model with floor.

Configure Your Walk-In Cooler

This product page allows you to build the walk-in cooler configuration that fits your project. Depending on your installation needs, you can choose from available options such as indoor or outdoor setup, door size, floor type, add-ons, refrigeration package, and layout.

Choose box only if you already have refrigeration equipment, are replacing an existing walk-in cooler box, or are working with your own refrigeration contractor. Choose top mount refrigeration if you want a package-style refrigeration setup mounted on the cooler. Choose remote refrigeration if your project requires the condensing unit to be installed away from the walk-in box.

Available options may include 30", 36", or 48" pallet-size doors, LED lighting, door kick plate, exterior ramp, no-floor or with-floor setup, top mount refrigeration, remote refrigeration, and multiple layout choices. Review each option carefully so the final package matches your building, storage workflow, delivery access, refrigeration plan, and daily operating needs.

Built for Large-Scale Commercial Cold Storage

The Astra 6 x 21 Walk-In Cooler No Floor is designed for commercial operations that need more than a standard walk-in cooler. Its long footprint gives restaurants, markets, commissary kitchens, catering operations, and foodservice businesses a practical way to manage larger refrigerated inventory without relying on multiple reach-in refrigerators across the building.

For operations handling bulk prep, regular deliveries, beverage storage, produce rotation, packaged goods, or multiple refrigerated product categories, this model can help turn cold storage into a more organized and efficient part of the business. The extended length gives your team more room to separate products, improve visibility, and move inventory through the cooler with less congestion.

Before placing your order, confirm your available space, floor condition, door swing, ceiling height, refrigeration requirements, electrical needs, and delivery path. The right configuration will depend on your building, your inventory volume, and how your team plans to use the cooler every day.
