Circular (main)
The combination of the fan and the circular
element (incorporated in the rear of the
oven) enables different foods to be cooked
on several levels, as long as they need the
same temperature and cooking time. Hot air
circulation ensures instant and uniform
distribution of heat. It will be possible, for
instance, to cook fish, vegetables and biscuits
simultaneously (on different levels) without
mixing smells and flavours.
