Hi-Temp Cartridges

• The ruggedly constructed, high watt density Hi-Temp Cartridge heaters provide excellent heat transfer efficiency, high operating temperature (up to 100 watts per square inch, depending on application) and long life.
• The Hi-Temp Cartridge is made to withstand a sheath temperature of up to 1400 °F (760 °C), internally up to 1600 °F (871 °C). Its swaged construction allows for minimal air gaps, providing superior heat transfer and resistance to impact and vibration. Dual voltage and three phase are available on selected diameters of the Hi-Temp.

Standard Cartridges

• Our Standard Cartridge heaters are designed as an economical, quality heater for lower temperature use (typically 40 watts per square inch, depending on the application).
• The Standard Cartridge Heater is made to withstand a sheath temperature of up to 1000 °F (538 °C), internally up to 1200 °F (649 °C), and features a stainless steel sheath for resistance to oxidation. High-purity magnesium oxide (MgO) fills any space around the resistor wire in order to optimize heat transfer and increase the life of the heater.

Features & Benefits

Hi-Temp

• Computer designed specifications.
• Incoloy sheath for oxidation resistance.
• Unique winding design allows faster heating and longer life
• Fine grain high purity magnesium oxide (MgO) fills any voids around the resistor wire to optimize heat transfer, dielectric strength and life of the heater.
• Cement seal is standard, RTV and Epoxy seals also available.

Standard

• Fine grain high purity magnesium oxide (MgO) fills any voids around the resistor wire to optimize heat transfer, dielectric strength and life of the heater.
• Resistor wire is joined to the leads by placing each end into nickel chromium which, upon crimping, affords a positive and consistent junction.
• Ceramic cap standard; cement, epoxy or RTV seal also available.
• Disc end of the heater rests on a mica insulator and is held in position when the sheath is rolled over onto it. This is a standard assembly procedure unless the application requires moisture or waterproof sealing, at which time the end cap can be sealed by brazing or welding.

Tutco offers a variety of band heaters to accommodate any cylindrical application. Tutco's product offering ranges from the HT Mica Band using high temperature mica and sheath materials for your high temperature applications, to the better belly band used for compressor applications.
