Sizing
The smallest quick-ship models are around 6 feet in each dimension. Custom boxes can be built to virtually any size you need. A good rule of thumb to keep in mind is that you should subtract 6 inches in each direction to know the actual interior dimensions. Each insulated wall will take away about 6 inches from the interior. To save money both up front and on energy costs in the long run, get as close an estimate as you can to how much space you’ll need inside. With a walk-in cooler that’s too big, you’ll be paying to cool space you don’t need. If you overfill a box that’s too small, it won’t be able to maintain safe temperatures. It is best to plan your shelving around the specific dimensions of your new unit. Since the doors of most walk ins are about 30-inches wide, the aisle inside doesn’t need to be much wider than that, unless you want enough room inside to turn a cart around. As an example, a common overall width is 9 feet. This leaves 8 feet of interior space, with 2 feet on each side for shelving and 4 feet in the center to maneuver a cart. The height of most boxes is between 6 and 8.5 feet. Shorter models are sometimes chosen for indoor installations, while taller one are better outdoors, where vertical clearance for a top-mounted refrigeration system is not a concern.
Refrigeration Systems
Two main types of walk-in refrigeration systems are available. Self-contained systemsoffer the simplest installation and operation. These come with the evaporator and condenser in one unit that bolts onto the side or top of the box.
Panel Materials
The exteriors of a walk-in fridge takes a lot of abuse. We use a aluminum to build them:
- Aluminum is the most economical choice. It is lightweight and will not rust.
