A 6 x 8 ft walk-in freezer at -10 F that still plugs into a 115 V circuit. A good fit for a restaurant that has outgrown reach-in freezers.
Amazon $11,996.38A walk-in cooler is an insulated room built from interlocking foam panels, with a door and a refrigeration system sized to hold it at about 35 to 38 F. A walk-in freezer is the same idea, with thicker-rated panels, an insulated floor and a system that holds -10 F. These rankings cover the prefab kits sold with a listed price, from Norlake, AmeriKooler and Kolpak, and the cooling units used to run a walk-in or a DIY insulated room: CoolBot controllers, window-style cooler units, monoblock units and split systems. Custom-quoted walk-ins and refrigerated trailers are left out.
Floor or no floor is the first choice. A floorless kit sits on vinyl sealers over an existing slab, which must be level, sealed and, for a cooler, ideally insulated. It costs less and has no step at the door. A kit with an insulated floor can go on any level surface and is required for a freezer, since a freezer on bare concrete freezes the ground under it.
Power is the second. Several of these kits plug into a 115 V receptacle, though most need a 20 A circuit. Larger boxes and the AmeriKooler kits need 208-230 V, which may mean an electrician.
Refrigeration is the third. A kit with a ceiling-mounted, self-contained system arrives ready to plug in. Building your own room instead means choosing a cooling unit: a CoolBot with a household air conditioner is the cheapest way to a cooler, a monoblock unit runs a cooler or freezer once it is wired, and a split system needs a refrigeration technician to install and charge.
