Used in Chemical and Petrochemical, Oil and Gas Industry, Industrial processes, Mobile processing plants and Vacuum processes.
MI-trace heaters consist of a twin conductor series trace heater connected to mineral-insulated cold leads (with 2,0, 2,5, 3,3 or 5,0 mm² copper conductor) by means of a clean laser seal (splice). The outer sheath is made of high quality stainless steel 1.4541 (AISI 321). The free end of the cold lead is potted and fitted with a flexible lead (cross section matching that of the cold lead conductor) for power connection and a 1,5 mm² lead for earthing. A com-pression ring flameproof stainless steel gland 1.4404 (AISI 316L) threaded M20x1.5 or M25x1.5 is fitted at the end of each cold lead and prevented from possible loss by the potted end seal. MI trace heaters are supplied prefabricated by eltherm and ready for installation. Each unit comes with a type plate bearing all information / markings. Maximum maintain temperatures are derived from the maximum sheath temperature determined by eltherm and are also indicated on the type plate.
