The oven is equipped with two fan engines, one in the top part and another in the bottom part. The ventilation flow is horizontal.
A cooling system composed of an air cooling extractor and of an inlet and an outlet with motorized flaps, is controlled by the controller: if the measured temperature exceeds the set point temperature with at least 2°C, the air inlet and outlet open entirely and the extractor works. The air inlet is equipped with a G4 filter in order to avoid that impurities enter in the oven.
When the oven works, heating, ventilation and cooling are cut off at each door’s opening.
