These are complete walk-in cooler kits: insulated panels, a door and a ceiling-mounted refrigeration system matched to the box. Sizes run from 6 x 6 ft to 10 x 10 ft. The floorless versions cost less and suit a building with a sealed, level slab; the versions with an insulated floor go on any level surface. Norlake’s kits plug into 115 V, while AmeriKooler’s better-insulated R-29 kits need 208-230 V.
