Metric FIREROD® Heaters 

The Watlow FIREROD not only sets the industry standard for cartridge heaters, but continues to make improvements in construction and design. Among those improvements is the FIREROD metric cartridge heater, a variation of the FIREROD cartridge heater built to meet the exact specifications of the global market.

Like its counterpart, the metric FIREROD consistently outperforms other cartridge heaters with its design solutions such as its exclusive resistance wire winding and swaging process. These processes bring the resistance wire closer to the sheath and compacts the MgO insulation to maximize heat transfer. The end result is longer service life and better efficiency.

Specifications:

Applications:

  • Semiconductor chamber heating
  • Semiconductor water 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 heating in injection molding equipment
  • Seal bars used in packaging equipment

Features & Benefits:

Features Benefits
Nickel-chromium resistance wire
  • Assures even and efficient distribution of heat to the sheath because the wire is precisely wound and centered in the heater
Conductor pins
  • Ensures a trouble-free electrical connection because of the metallurgical bond between the conductor pins and resistance wire
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 or 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
  • Insulates the wires to temperatures of 250°C (480°F)
Patented lead adapter (LA) method
  • Allows same day shipment on more than 150,000 configurations of stock FIREROD heaters and lead combinations
