Commercial refrigeration is much different. First, is their ability to maintain constant temperature, which is mandated by health code. Also, the insides are a cleanable, washable, and usually made of stainless steel or aluminum. There are downsides to their use in a domestic kitchen. First being the noise. The compressors on commercial fridges are bigger, and much louder. They lack a lot of the noise insulation found in home fridges. Air-cooled units also give off a lot of heat, something to think about in a house. Water-cooled units cost more, can leak, need to be plumbed, and cost more to operate. To get more information, call on a commercial kitchen appliance store or installer and get advice from an expert.
You best bet is probably one of those "hybrids" that look like commercial stuff but are made to be in your house.
