Oval tube heaters are mainly used for efficiently heating tools and workpieces. In most cases the oval tube heaters are fixed to the tool by a clamping mechanism to keep the workpiece to temperature. Frequently, these heating elements are used to keep a plant section free from frost and/or the adjacent fluid (weir, rail or valve heating and the bottom heating of a tank as well). Oval tube heaters consist of a tube with a flat oval cross section where the heating coil is in its middle and converts electrical energy in thermal energy. This heating coil is fixed by a highly heat-resistant ceramic material (magnesium oxide) and is electrically insulated against the heating element sheath at the same time. The compacting process makes sure that the heater coil is held in position and can well dissipate its thermal energy to the outside.
