Code No. FCH M-T-D, FIREROD Cartridge Heaters (Made-to-Order)




  • Part temperatures up to 1400ºF (760ºC) on Incoloy® sheath
  • Watt densities up to 400 W/in2 (62 W/cm2)
  • Maximum voltage up to 480V
Diameter
  • 1 in. (25 mm) units: ±0.003 in. (±0.08 mm)
  • All other units: ±0.002 in. (±0.05 mm)
Length
  • All units to 4 1/2 in. (114 mm) long: ±3/32 in. (±2.4 mm)
  • 1/8 in. diameter units over 4 1/2 in. (114 mm) long: ±3%
  • All other units over 4 1/2 in. (114 mm) long: ±2%
Wattage
  • 1/8 in. units: +10%, -15%
  • All other units: +5%, -10%
Resistance
  • 1/8 in. units: +15%, -10%
  • All other units: +10%, -5%
Resistance changes with temperature. There are three circumstances under which resistance can be measured:
  1. Room temperature (before use): nominal ohms are 90% of ohm’s law calculation.
  2. Room temperature (after use): nominal ohms are 95% of ohm’s law calculation.
  3. At temperature (during use): depending on application nominal ohms are approximately 100% of ohm’s law.
Note: Resistance and wattage values are approximate depending on application conditions.

Camber
Units to 12 in. (305 mm) long: 0.005 in. (0.1 mm) per 6 in. (152 mm) length. Standard camber tolerance varies as the square of the length, in feet, is multiplied by 0.020 in. (0.5 mm). For example, a 36 in. (914 mm) FIREROD has a camber tolerance of 0.020 in. x (3)2 = 0.180 in. Normally, slight camber does not present a problem since the heater will flex enough to fit into a straight, close fit hole.

Component Recognition File Numbers
  • UL® component rated to 480VAC
  • CSA component rated to 240VAC
  • VDE component rated to 480VAC
  • CE component rated
Note: Not all options or combination of options are covered. UL®, CSA, VDE and CE marking is available upon request.

Standard Lead Specifications

Lead length tolerances:
1 to 36 in. (25 to 914 mm) = -1/2 in. (13 mm), +1 1/2 in. (38 mm)
> 36 to 72 in. (914 to 1829 mm) = -1, +3 in. (-25 + 76 mm)
> 72 in. (1829 mm) = ±4 in. (102 mm)

SS hose and braid tolerances: same as lead wire.

Units constructed with 480V require MGT or Teflon® leads. If connecting heaters in series above 300V, MGT leads are also required.

Ratings:
GGS, 300V, 482ºF (250ºC)
MGT, 600V, 842ºF (450ºC)
Teflon®, 600V, 392ºF (200ºC)
Silicone rubber, 600V, 302ºF (150ºC)


Features and Benefits

Nickel-chromium resistance wire
  • Assures even and efficient distribution of heat to the sheath
    Conductor pins
  • Provides a metallurgical bond to the resistance wire
  • Ensures a trouble-free electrical connection
    Magnesium oxide insulation of specific grain and purity
  • Results in high dielectric strength and contributes to faster heat-up
    Incoloy® sheath
  • Resists oxidation and corrosion from many chemicals, heat and atmospheres
    Minimal spacing between the element wire and sheath
  • Results in lower internal temperature
  • Accommodates a design with fewer or smaller heaters operating at higher watt densities
    UL® and CSA approved flexible stranded wires
  • Lead insulation rated to temperatures of 480ºF (250ºC)
    Patented lead adapter (LA) method
  • Allows same day shipment on more than 150,000 configurations of stock FIREROD® heaters and lead combinations


  • Typical Applications

    • Semiconductor chamber heating
    • Semiconductor wafer lead connection
    • Semiconductor wire and die bonding
    • Freeze protection and deicing of equipment in cold climates or applications
    • Humidity control
    • Patient comfort heating used in medical devices
    • Mold die and platen heating
    • Seal bars used in packaging equipment
    • Test sample heating in gas chromatography equipment



    Heating Solids

    These heaters are inserted into a close fit hole (i.e. platens, dies and molds)


    Heating Liquids/Surface Heating and Immersion

    These are used as an immersion heater placed either directly in the liquid, or in a protective well (Recommended for immersion in water or 90 plus percent water soluble solutions).


    Heating Gases

    These heaters are mounted in pipes or vessels through which gases pass. They can be placed in protection tubes, making access and wiring easier.


    Heating Within a Vacuum

    These heaters are mounted in a vacuum vessel for radiant energy transfer.
