The MI strip heater is a thin, responsive heater setting unmatched
standards for performance and durability. The 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.
