Walk In Refrigeration Boxes
With or Without Refrigeration
Many models of walk-in are available with integrated cooling systems (compressor and condenser) which makes it easier to purchase everything at one time. You must determine where the integrated cooling system is located on your unit, since side mount or top mount configurations can increase the required space for installation. However, other models come with no compressor/condenser units and you must supply your own remote cooling system. Typically the remote refrigeration system will be mounted externally (on the roof, for example). With these remote configurations you have more options for layout and installation to meet your needs.

Walk-in Cooler Boxes
Some walk-in coolers come with no compressor/condenser units, consisting only of the wall panels, door panel, and roof of the unit. These walk-in boxes will come without any cooling system and you must supply your own remote cooling system. Typically the remote refrigeration system will be mounted outside the facility, externally (on the roof, for example) or in another location some distance away. Most manufacturers have designed specific cooling systems to properly function with their remote-cooled walk-in boxes, so be careful to select the appropriate refrigeration system for one of these walk-in boxes without mounted refrigeration.

Walk-In Freezer Boxes
Some walk-in freezers are available as refrigeration compartments that only consist of the wall panels, door panel, and roof of the unit. The benefit of this design is that you can select the size condensing unit and install it in another location than where the walk in box is installed. Typically the remote refrigeration system will be mounted outside the facility, externally (on the roof, for example) or in another location some distance away. While there are options for condensers for these walk-ins, many manufacturers have designed very specific proprietary cooling systems to properly function with their walk-in boxes, so when choosing these components, select one of the recommended refrigeration systems.
