This type of oven uses an overhead conveyor for transportation of the cargo through the oven and it has one or several heating zones and it can also be delivered with a cooling zone if needed. The conveyor is step-fed and the hatches are motor driven. The oven can also be equipped with one or several inspection hatches along the long sides if needed.
