When purchasing a walk-in refrigerator or freezer, foodservice operators have many factors to address. Here are 11 factors that should weigh into any purchasing decision.
Walk-ins typically have a service life of approximately 15 years, but there are units that have been in operation for more than 20. When purchasing a new unit, foodservice operators should consider a number of factors.
Determine what products the walk-in will store. Depending on an item's density and temperature, it may take longer to pull down to the correct temperature, thus requiring a larger refrigeration system.
To figure out the necessary capacity, keep in mind that 1-cu.-ft. of open storage area accommodates approximately 28 lbs. of solid food.
Doors are an important consideration, since they receive most of the day-to-day abuse. If frequently opened and closed, a heavy-duty door may be necessary. Automatic closing devices, like cam-lift hinges and a positive door closer, ensure the door isn't accidently left open. If it's necessary to see what's inside the walk-in, a view window should be specified. Kick plates on the door and inside the walk-in are also helpful in preventing damage. Strip curtains can help keep out unwanted outside air during high-volume use.
Consider the weight and frequency of traffic to determine what type of flooring is necessary. If staff will use heavy-loaded to transport items into or out of the walk-in or there will be heavy shelving inside, a reinforced or structural floor may be appropriate.
If the walk-in will have floor panels, interior or exterior floor ramps can provide easier access.
Walk-ins require at least 2" of space between the walk-in ceiling and building as well as a minimum of 1" on all sides for proper ventilation.
Determine if space requirements will change or if there will be a future need to move the walk-in. This would necessitate cam-locking panels, which provide easy dismantling of the unit.
If the refrigeration system will operate in a hot environment, a larger size may be needed.
Maximum use of storage space is another consideration. Polyurethane panels, because of their greater efficiency, can be much thinner and still meet R-factor requirements. As a comparison, it would take approximately 8" of polystyrene or 33" of solid wood to equal the insulation value of 4" of polyurethane. Thinner panels equal more usable space.

White interior finishes can create a brighter environment and make the walk-in's contents more visible.
