commercial reach-in for home use
No reason why you can't. But they are louder, and do suck up more power
Some things to consider.
The main difference is that a commercial fridge or freezer goes on defrost cycle every 8 hrs, usually for a 20 min. cycle.
The shelving is usually crappy. For the most part, it is plastic coated wire shelving. If and when you spill anything on the shelving it is a lot of work to clean up. The shelving also sags over time and with wieght, say milk in gallon jugs. When it sags, it pops out of the standards and you have a mess inside the fridge.
Parts and service will be more expensive than for residential units.
Other than that, they're great
