Easy cleaning to ensure highly sanitary environments

Every Polar King walk in meat cooler and freezer is constructed of 100% seamless fiberglass coated on the interior with an anti-microbial finish. The continuous durable surface eliminates cracks and crevices where moisture and bacteria can hide and also stands up to harsh cleaning chemicals, making cleanup a snap with a mop or power washer.

Humidity control systems for meat hanging coolers

Humidity plays an essential role in preserving the quality, safety, and appearance of fresh meat. Excessive humidity helps create an environment where bacteria can thrive and cause meat to spoil faster, while overly dry air can dehydrate meat and reduce its weight and quality. The seamless fiberglass construction of Polar King’s meat hanging coolers minimizes air infiltration, temperature variations, and moisture fluctuation, providing the ideal environment for storing large game or processed cuts.

If desired, we can customize your walk in deer/game cooler or walk in meat freezer for specific applications, such as dry-aging meat or storing wild game long term, with humidity regulation and temperature management. We offer multiple systems to increase or decrease moisture or can design a custom system to provide precise humidity control.

Energy-efficient walk in meat coolers reduce operating costs

Panel boxes are usually assembled onsite, but all Polar King commercial meat coolers are built our factory in Fort Wayne, Indiana and arrive ready to go with just a simple electrical connection. This patented manufacturing process ensures that every walk in meat cooler and freezer we make meets our high standards of quality.

Competitors’ boxes typically use insulation that is foamed in between panels. But foam fills haphazardly, leaving gaps where heat can penetrate the unit. This causes hot spots that make the unit’s motor run more often, increasing operating costs and reducing the lifespan of the motor.

Instead of foamed-in insulation, Polar King uses 4’ polyisocyanurate rigid board insulation for meat coolers and 5” insulation for walk in meat freezers and completely encapsulates the board in seamless fiberglass. This one-piece construction creates a strong, freestanding unit and protects the insulation from air and moisture that can cause it to deteriorate.

Polar King walk ins have a high R-value of at least 25 for coolers and 32 for freezers, performing exceptionally well during high-temperature testing in Texas above 175°F.

Frequently Asked Questions

What temperature range should a meat hanging cooler run at for safe storage and aging?

Set your meat hanging cooler between 28°F and 35°F to slow bacterial growth and maintain quality. While USDA food safety guidance references 40°F or below as a safety threshold, most meat operations run colder to meet their specific product and process needs.

How do I choose the right size walk in meat cooler for my butcher shop or processing operation?

Size your cooler around peak volume: how much meat you’ll hang at once, how much boxed product you stage, and the aisle space you need to work safely. Plan for growth so you’re not maxed out when production ramps up. We’ll build custom sizes and tailor interior heights and widths to match your hanging pattern and workflow.

What accessories are available for a meat cooler?

We offer butcher hooks, overhead rail systems, humidity control, vinyl strip curtains, stainless steel kick plates, reinforced floors, custom finishes, and wider doors (up to 54 inches).

Need easy cleanup? Pair an optional floor drain system with our standard seamless interior surfaces for hassle-free sanitation.

What’s the best walk-in deer cooler setup for hunters and game processing?

A good deer cooler setup chills quickly, holds a steady temperature, and provides enough hanging space for airflow around the product. We can custom-build a walk-in deer or game cooler sized for your aging and storage needs. If you’re dealing with variable conditions, we’ll incorporate humidity regulation and temperature controls to keep things stable.

What’s the ideal layout for a meat hanging cooler to maximize airflow and hanging capacity?

An ideal layout spaces product for airflow and leaves clear working aisles so teams can hang, move, and process safely. Layout directly affects how well the room maintains temperature during daily use. We tailor interior dimensions and rail placement to fit your workflow—not force you into a one-size-fits-all setup.

Can a walk in meat cooler be used for dry aging beef, and what features help support consistent results?

Yes. We customize meat hanging coolers for dry-aging with humidity regulation and temperature management for stable conditions. Our seamless fiberglass construction minimizes air infiltration and moisture fluctuation to maintain consistency.

Are Polar King walk-in meat coolers and freezers certified for foodservice and regulated environments?

Yes. Our walk-in meat coolers and freezers have NSF/ANSI 7 certification and CSA approval. Need documentation for a submittal or inspection? We’ll get you the certification information for your specific configuration.

Can a Polar King meat cooler be installed outdoors, and what building-code approvals are available for severe weather areas?

Yes. Our meat hanging coolers and freezers are standalone structures built to meet strict building requirements for outdoor use. They’re approved for high-velocity hurricane zones and meet Florida Building Code requirements, including Miami-Dade County Product Control approval for impact resistance.

Does Polar King offer floor drains for your meat coolers?

Yes! While not a standard feature, one of our cooler’s most popular add-ons is a floor drain/drainage system which allows for frequent washdowns while avoiding standing water and contamination.
