They are built with a structure of AISI 316 stainless steel while the base is a steel painted with epoxy paints sheet. The thermal insulation is built with quality ceramic fibers, currently, among the most technologically advanced, while the heating part consists of resistive elements in “molybdenum disilicide”. The door is built with parallel opening operation with orthogonal system that allows to open and close the oven without ruining the door of the kiln itself and not have the hot part in contact with the operator.
