Custom-made Walk-ins for Brewery Applications

The Gnometown Brewing Company, Indiana’s first nanu-nanu brewery, required a walk-in cooler that could not only hold refrigerated products and beverages, but also be able to store and distribute kegs of beer.

This 7’x16’ through-wall Polar King walk-in cooler and beer refrigerator unit was custom built for a nano brewery in Fort Wayne, Indiana. This particular unit is a walk-in cooler that has several custom features to accommodate beer tap lines and the increased weight of beer kegs.

Frequently Asked Questions

How is a brewery walk in cooler designed differently to handle the structural and operational demands of keg storage and distribution?

A brewery walk in cooler is typically built with a heavier-duty floor system to handle the concentrated weight of full kegs, along with wider doors to allow hand truck and pallet jack access. Tap line penetrations, regulators, and stainless steel interior finishes are common additions for distribution-facing configurations. Units serving both cold storage and active dispensing functions require careful planning of interior layout and line routing to keep the workflow efficient.

For operations that need a detailed look at how these configurations come together in practice, the Gnometown Brewing Company build at polarking.com/portfolio/gnometown-brewing-co/ is a documented example of a through-wall brewery walk in cooler configured for keg storage and tap service.

What specifications should I consider when sizing and configuring a walk in keg cooler for a bar or brewery?

Keg capacity depends on unit dimensions and stacking configuration. As a reference point, a 7’x16′ Polar King walk in keg cooler can hold approximately 40 double-stacked kegs. To support safe keg handling, units can be specified with reinforced flooring rated for the added weight load, wider doors up to 36 inches to accommodate hand trucks and pallet jacks, and pallet bumper guards to protect the interior walls during loading and unloading. Because Polar King units are installed outdoors, the refrigeration system is self-contained on the unit: the evaporator sits inside the unit where it collects heat, while the condenser and compressor are mounted on an exterior wall shelf or on the roof of the unit, keeping mechanical noise outside the bar or taproom environment.

What does a walk in cooler with beer taps require in terms of interior configuration and line routing?

A walk in cooler with beer taps requires tapper lines and regulators routed from inside the unit to tap handles mounted on the exterior wall. The tapper lines and regulator sit inside the cooled space to keep the product at serving temperature, while the taps are accessible from the bar or service area outside the unit. A stainless steel backsplash is commonly installed behind the tap penetrations to protect the interior wall surface. The number of taps, line layout, and penetration locations are determined during the custom build process based on the establishment’s service setup.

Can a commercial walk in beer cooler be installed as a through-wall unit in an existing building rather than as a freestanding outdoor structure?

Yes. Polar King commercial walk in beer coolers are available in both through-wall and freestanding configurations, making them compatible with new construction and retrofit installations in existing buildings. In a through-wall setup, the unit is positioned outside the building with a door opening cut through the exterior wall, giving interior access to the cooled space without occupying floor space inside. The custom build process accounts for wall thickness, door placement, and any structural requirements specific to the installation site.

What exterior customization options are available for Polar King walk in beer coolers?

Polar King walk in beer coolers can be finished with exterior treatments from our Architectural Series design package, which includes brick, stucco, and tile patterns, as well as custom paint colors matched to a provided PMS sample. Branded graphics and signage can also be incorporated into the exterior design for retail and taproom environments where the unit is visible to customers. Structural options such as parapet walls are also available, to conceal rooftop refrigeration equipment from view.
