External steam generation 

The benefits of external steam 
Innovative steam system: unlike other systems, the steam is generated outside the oven compartment in our appliances. The steam flows into the oven compartment at high speed and displaces the oxygen. This results in fast heating and optimum temperature measurement and preserves the natural colour of the food. And because limescale cannot build up in the oven compartment, cleaning is particularly easy.
