A commercial range is a core piece of equipment that many restaurants cannot do without. Ranges are used to cook, grill, broil or perform many other cooking tasks that your kitchen requires. Various sizes and top configurations are available to suit a restaurant's specific needs.Most restaurants will need either a heavy-duty or standard-duty commercial range. Cafeterias, dining halls or large restaurants will want to go with a heavy-duty model because it is designed to keep up with the demands of a high-volume kitchen. Smaller restaurants should only need a standard, restaurant-style model.
