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