This type is “U”-shaped, consisting of a combination of one each of the EREMA types E and F respectively. It is a single-phase heating element with both cold ends in one direction, facilitating increased furnace design flexibility, because connection terminals can be centered on one side. In addition, a furnace with an energy saving structure can be built because the number of heating element holes on the furnace can be reduced compared with the E or F types.
