Many foodservice companies use walk-in coolers because they provide a lot of cold storage space. When searching for the perfect unit, determine whether it will be placed indoors or outdoors, if you need a floor or not and the overall dimensions. One of the first things you need to think about when looking for a walk-in cooler is whether it will be used inside or outside. Units that will be placed outside will need an appropriate coating on the exterior metal to protect it from the elements. The compressor will also need an adequate cover.

​

   For units that will be placed inside, there will be a separate room all to themselves. Finding the right sized unit to fit the available space may be a bit of an assignment. Whether installing a walk-in cooler in an existing building or during the construction phase of a new facility, you will want to take into account the compressor size and location as well as the overall size of the unit. Remember that each wall has about four inches of insulation so that the interior dimensions will be slightly smaller than the exterior.

​

   Another consideration to keep in mind when searching for a walk-in cooler is whether you need it to come with a floor or not, they can come either way. The floors that come with the unit are usually a grooved or textured metal. Many establishments lay their tile floors inside the walk-in coolers for a more customized look, or to match the flooring of the rest of the kitchen.
