Cartridge Heaters
What is a Cartridge / Insertion Heater?
Cartridge or insertion heaters are typically tube-shaped industrial heating elements that are inserted into drilled hole. A cartridge heater provides a precise localized conductive heating solution for many industrial applications. A tight fit is important as it provides proper thermal conductivity. Proper heat transfer will improve the cartridge heater life expectancy.
The TUTCO Cartridge Heater Advantage.
TUTCO Cartridge / Insertion heaters are available in high- temperature and standard models that provide excellent heat transfer efficiency and a watt density of up to 100 W/in2.
Hi-Temp Cartridge Heaters offer the very best price per performance ratio with the highest number of customizable options. A tight fit is critical as it provides proper thermal conductivity. Proper heat transfer will improve the cartridge heater life expectancy.
TUTCO offers two cartridge / insertion heater styles, Hi-Temp and Standard. The Hi-Temp Cartridge Heater is an extremely durable swaged insertion product made for high temperature applications. It is made to withstand a sheath temperature of up to 1400 °F (760 °C), internally up to 1600 °F (871 °C). Its swaged construction provides superior heat transfer and resistance to vibration.
TUTCO also stocks many standard cartridge heaters with a maximum sheath temperature of 1000°F (538°C). Dual voltage and three-phase options are available on select diameters. TUTCO engineers can work with you to design and manufacture custom cartridge / insertion heating solutions in multiple shapes, lengths, connectors and with distributed or zoned wattages.
Applications
TUTCO electric cartridge heaters are ideal for applications with high heat and excessive vibration characteristics including industrial machines processes like hot stamping, heat-staking, sealing bars, forming and heating platens. Cartridge heaters are commonly used in food, pharmaceutical, packaging, plastics and other industrial markets. Cartridges can be modified to meet the demands of special applications. It is not uncommon to find insertion heaters in pellet stoves, recreational vehicle furnaces and refridgerators, electronic control cabinets, aerospace, aviation and automotive applications. Our engineers can utilize a variety of alternative features and options to customize the heater to your specific needs.
Two cartridge heater styles are offered. The Hi-Temp is an extremely durable cartridge heater manufactured with a swaging process and used where high operating temperatures are required. It 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 a dense heater construction with superior heat transfer and resistance to impact and vibration. We also offer a standard cartridge heater with a maximum sheath temperature of 1000 °F (538 °C). Dual voltage and three phase options are available on select diameters. We can also work with you to design and manufacture cartridge heating elements with distributed or zoned wattages.
Applications
Tutco manufactures electric cartridge heaters ideal for applications with high heat and excessive vibration characteristics. Applications like hot stamping, sealing bars, forming and heating platens may have parts best suited for a rugged high temperature cartridge heater. Like our Standard models, many options are available to customize our Hi-Temp Cartridge heaters. Choose Hi-Temp for applications involving high heat and/or excessive vibration. A swaged construction and the appropriate diameter will yield the longest heater life. Consult the factory for additional information and product options to meet your specifications.
