Schniewindt equips the first heating element with its so-called Giso closure method and integrated thermocouple thereby achieving optimal operating data for a trouble-free operation of heat transfer systems. Giso doesn’t use conventional silicon to seal the ends of the heating rods against moisture but a proprietary component. So humidity can’t diffuse into the heating element, led to a drop of the insulation resistance. The heating element is offered in two ratings at 15 and 25 kW. The heating cartridge used is highly compressed at a diameter of 32 mm thereby providing a good heat transfer from the heat conductor to the surface. Because of the integrated thermocouple, the temperature curve, for the first time, is measured in the heating element itself, facilitating precise control. If, due to surface deposits, the temperature increases to a value critical for the life of the heating cartridge, then this is shown on a display in the control room. The heating element can be dismantled and cleaned in a timely manner.
