Watlow Strip Heaters

  • 375 Finned Strip
    The 375 finned strip heater from Watlow is constructed
    of highly-compacted magnesium oxide (MgO) based
    insulation, which conducts heat efficiently from the nickel
    chromium element wire to the sheath. Two-inch wide
    (51 mm) nickel plated fins are attached to maximize
    surface contact allowing heat to transfer into the air
    faster. Lower sheath temperature and element life are
    maximized by this finned construction.
    MI Strip
    The MI strip heater is a thin, responsive heater that uses
    the most advanced heater construction techniques.
    A nickel-chromium element wire is embedded in Watlow’s
    exclusive mineral insulation material, which has 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.
    The result is heat flows easily from the element wire to the
    sheath allowing the wire to run cooler than conventional
    heaters and increasing heater life.
