Commercial chest freezers are especially useful for back of the house storage. They arenít particularly attractive but can efficiently store a lot of product. When considering which commercial chest freezer will work best for you, there are several key features that merit keeping in mind. The first is the type of lid or door it has. Sliding doors take much less vertical space to open, but you can only access half of the freezer at a time. Flip-up lids or doors give you access to the entire chest freezer, but you need to be sure to leave enough clearance above to allow the door to open.
