Hi-Temp Cartridge Heaters


Hi-Temp Cartridge Heaters

TUTCO Cartridge heaters are high watt density heaters that provide excellent heat transfer efficiency and up to 100 W/in2 with high operating temperatures. 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 options are available on selected diameters.
