30" Double Electric Built-In Wall Oven
Maximize your kitchen’s output with Cosmo’s 30 inch double electric wall oven. Two 5 cu. ft. ovens give you the flexibility to manage multiple dishes and cooking temperatures at once, and the capacity to feed a crowd. The upper oven is equipped with true European convection to bring your dishes to life faster and tastier than ever, cooking at an average of 25° cooler and 10% faster than a traditional oven. Automatic convection conversion means you don’t have to do the math to adjust your recipes either. Our ovens are equipped with 7 different functions to make this a truly versatile appliance- Bake, Broil, Warm, Proof, Convection Bake, Convection Broil and Convection roast. Both ovens feature our brilliant blue oven cavity finish, six oven rack positions, and a self-cleaning function to take the elbow grease out of appliance maintenance. When you upgrade your kitchen with Cosmo Appliances, you bring professional quality home at factory direct prices.
