Mineral Insulated Strip Heaters

The Watlow MI strip heater is a thin, responsive heater that sets unmatched standards for performance and durability. These mineral insulated strip heaters make use of the most advanced heater construction techniques, including embedding a nickel-chromium element wire in an exclusive mineral insulation. Watlow’s exclusive mineral insulation is a material with a much higher thermal conductivity than the mica and hard ceramic insulators used in conventional heaters. This thin layer of insulation brings the element wire closer to the heater sheath, resulting in easy heat flow from the element wire to the sheath. This allows the wire to run cooler than conventional heaters and increases strip heater life.


  • Stainless steel construction, with sheath temperatures up to 1400°F (760°C)

  • Maximum voltage 480VAC
  • UL® component recognition for most 240VAC or less designs (UL® File #E52951)


  • Solder pots
  • Zinc die-casting equipment
  • Die and mold heating
  • High-temperature resins
  • Tank and platen heating
