Hi-Temp Cartridge Heaters


Hi-Temp Cartridge Heaters

TUTCO Hi-Temp Cartridge heaters are high watt density heaters that provide excellent heat transfer efficiency and up to 100 Watts/in² with high operating temperatures. The Hi-Temp Cartridge is made to withstand a sheath temperature of up to 1200°F (649°C) continuously and 1400°F (760°C) intermittently. Its swaged construction allows for minimal internal air gaps, providing superior heat transfer and resistance to impact and vibration. Dual voltage and three phase options are available on selected diameters.
