From defrosting frozen foods to simple reheating or cooking an entree, a commercial grade microwave is the most efficient method to prepare food in a fast service environment. It will quickly heat sandwiches, breakfast pastries and other packaged foods and is perfect for small restaurant operations, convenience stores, cafes and quick serve kiosks. Commercial microwaves generally have more power than residential microwaves and are offered with a wide range of power and programming options. Light duty microwaves have wattage about 1000 - 1100 watts, medium duty 1200-1800 and heavy duty 1800 or higher.
