A commercial dishwasher is a large machine used to wash dishes in restaurants, hotels, schools, and other public and private establishments. These dishwashers are large enough to accommodate large platters and other pieces of large kitchen equipment. They usually have a conveyor system to move the dishes through the washer, allowing you to stack them up, and they may have an integrated sink to fill and empty the machine. They are usually designed to connect to your plumbing to supply and drain water. They will usually have a connection for a drain to take away the wastewater.
They are usually made from stainless steel, which is easier to clean and will resist rust. They may have options for precise water temperatures for different materials and uses. They may have options for loading and unloading the dishes, such as a conveyor or lift.
