Basically, there are two types of ovens – table top or built-in, ovens are measured by the size of volume, or so-called gross water content. IZOTON has 17L and 40L ovens for table top. The 40L is equipped with turbo fan to make the heat more even for all kinds of cooking and is well-designed for cake baking. In modern days, more and more people would prefer to have their ovens built-in in the cabinet; IZOTON has two types for built-in ovens – 56L & 80L. Each of them has 7-function for user to select the choice of baking/grilling. You are most welcome to browse through our website for your choice of ovens. Again, under the brand of IZOTON, we emphasize strongly on quality, safety & durability.
