Appliances built for commercial settings are the workhorses of the industry. They do more work, put in longer hours, and take more abuse. Makers of such appliances keep busy, too, always looking for ways to make their products, and users of the products, work smarter. Some key objectives for designers of commercial appliances include easier and safer operation, better performance, reduced energy and water consumption, more sophisticated controls, and networking systems to help owners optimize the use of their equipment investments. In many cases, these innovations can also boost revenues.
