The new BTS1 is the dual-cooking electric oven from Samsung. The oven interior has the divider designed from two steel plates with a layer of air in between. The result is an adjustable cooking space that provides a range of cooking options in a compact, energy efficient design. Basically you get two ovens in the space of one, so you can cook one large dish and a small dish or two dishes with different cooking requirements at the same time. The BTS1 divider plate blocks the flow of heat and smells between the two cooking spaces. Samsung.
