BTS1 is an electric oven that is the first in the world to offer a dual cooking function in one cavity. The user can cook a big dish or two dishes at the same time by using the divider plate. The oven automatically recognizes the divider so that the user can adjust the temperatures separately and to prevent the mixing of smell. The UI layout is also based on the dual convection function. The steam self-cleaning function cleans the inside of the oven in just 20 minutes. By saving 25% more energy when compared to other products, this became the first of its kind to obtain the "AAA mark" (Tested by VDE), proving its environment-friendliness.
