Strip Heaters (FS, SD, SS Series) Specialty Heater

Caloritech™ Strip Heaters are a versatile and economical heating source typically used across a wide range of applications, including surface heating (platens, dies, molds, tanks, piping); process air heating (drying cabinets, ovens, baking ovens, vacuum dehydrating ovens, moisture protection for motors); dropping resistors for line applications in railroads and load banks; winterizing (hoppers, conveyors, ducts, car heating, thawing); original equipment (air conditioning, laboratory equipment, food packaging, ovens, presses, drying equipment).

Features

  • Special refractory material possesses excellent heat transfer characteristics, superior insulation properties and rigid vibration resistance to provide a heavy-duty heating unit
  • Slotted mounting tabs allow lineal expansion during initial heat-up period
  • Rated at 120V or 240V, depending on size
  • Overall length limit of 42.5" (1080 mm); effective length limit of 39" (991 mm)
