Mineral Insulated Heater
Due to the superior features mineral insulated heaters are used in a wide range of industrial heating applications.
ThermSys provide as standard a range of mineral insulated heaters (MI-heater) with outside diameter 0,5mm up to 6,5mm with stainless steel sheath (e.g. AISI 304, AISI 304L, AISI 316L, AISI 321, AISI 316Ti) until 700°C or Inconel 600 sheath (2.4816) until 1000°C.
Special alloys like AISI 310S, Inconel 625, Inconel 800 or others can be offered on request.
