materials, magnesium oxide dielectric insulation, and resistance wire construction allow the tracing of surface up to 600°C maintain temperatures and excellent resistance to harsh & many corrosive environments. MI heating cables and heater units are widely used in areas where high temperature, high pressure, high radiation, or corrosive environments exist, and where high power density field, and electric heating or heating processes exist.
Advantages
Construction
Metal Sheath: High nickel content Alloy 600 & 825 is recognized for its use in high-temperature applications, and use in many corrosive environments. This alloy has excellent resistance to pitting, acid, and alkali corrosion. Stainless steel alloys are also available.
MgO: Highly compacted Magnesium Oxide provides insulation of the resistance Wire. A completely sealed sheath protects the MgO from moisture & contamination.
Resistance Wire: A large number of available resistances enables the design of a large range of lengths and wattage. Double and single conductors available.
