Cartridge Heaters Common Configurations

 

Cartridge heaters by Thermal Corp are high temperature swaged units manufactured with magnesium oxide insulation. Every cartridge heater by Thermal Corporation is a premium quality unit with your choice of standard stainless steel sheathing or if your process requires, an incoloy sheath which offers a higher temperature rating and higher resistance to chemical corrosion.

Crimped Leads
Style CL

Flexible stranded lead wire is crimped with a high temperature connector to the end of the solid conductor and electrically insulated with 1-1/2″ of high temperature sleeving.
Cartridge Heaters Configurations
Internally Connected Leads
Style SL

Internally connected leads offer maximum flexibility at point of entry to cap, allowing a high degree of flexing as well as the ability to bend the leads sharply adjacent to the cartridge heater.
Cartridge Heaters Configurations
Straight Braid
Style SB

Stainless steel braid protects leads from abrasion or sharp equipment while allowing flexibility.
Cartridge Heaters
Straight Hose
Style SH

Stainless steel hose protects leads from abrasion on sharp equipment while allowing flexibility.
Cartridge Heater
Teflon Leads
Style ST

Internally connected teflon leads seal and resist moisture and oil in applications up to 480°F. This option is available on 1/4″ to 3/4″ units. A minimum cold section of 5/8″ at the lead end is required.
Cartridge Heater
Teflon Leads with Braid
Style STB

Internally connected teflon leads seal and resist moisture and oil in applications up to 480°F at the lead end. This option is available on 3/8″ and 1/2″ units. A minimum cold section of 5/8″ at the lead end is required.
Cartridge Heater
Teflon Leads with Hose
Style STH

Stainless steel hose protects internally connected teflon leads and resists moisture and oil in applications up to 480°F at the lead end. This option is available on 3/8″ and 1/2″ units. A minimum cold section of 5/8″ at the lead end is required.
Cartridge Heater
Internal Sheath Thermocouple
Style JB or KB

Internal thermocouple junction is located adjacent to the inside heater sheath to monitor the part temperature.
Cartridge Heaters
Internal End Thermocouple
Style JC or KC

Internal thermocouple junction is located at the end disc to monitor the material flow past the end of the heater.
Cartridge Heaters
Ceramic Bead
Style CB

Ceramic bead insulation protects the leads from high temperature environments (above 500°F / 260°C). The beads fit over the solid conductors which extend far enough to reach a cooler area where flexible wires can be attached.
High Temperature Swaged Cartridge Heaters
Right Angle Leads
Style NRL

Right angle leads offer high flexibility and are often used when space limitations are critical. Not available with internal thermocouple.
High Temperature Swaged Cartridge Heaters
Right Angle Hose
Style NRH

Right angle stainless steel hose protects leads from abrasion or sharp equipment and is often used when space limitations are critical. Not available with internal thermocouple.


High Temperature Swaged Cartridge Heaters
Right Angle Overbraid
Style NRB

Right angle stainless steel braid protects leads from abrasion and is often used when space limitations are critical. Not available with internal thermocouple.
High Temperature Swaged Cartridge Heaters
Copper Elbow with Leads
Style CE

Copper elbow offers right angle exit of leads used when space limitations are not as critical. Available with internal thermocouple.
High Temperature Swaged Cartridge Heaters
Copper Elbow with Hose
Style CH

Copper elbow with hose for right angle exit of leads with protection against abrasive environment. Used when space limitations are not as critical. Available with internal thermocouple.


High Temperature Swaged Cartridge Heaters
Copper Elbow with Braid
Style CS

Copper elbow with braid for right angle exit of leads with protection against abrasive environment. Used when space limitations are not as critical. Available with internal thermocouple.
High Temp Cartridge Heaters
Post Terminals
Style PT

Post terminals provide a fast, neat connection to ring, spade connectors or bus strips. Threaded 10-24 studs are brazed to the solid nickel conductor. Available only in 5/8″, 16.5 mm, 3/4″ and 20 mm sizes.
High Temp Cartridge Heaters
Mounting Flanges
Style MF

Mounting flanges may be welded to heater at lead end and is available on all standard diameters. Recommended in applications involving excessive vibration.
High Temp Cartridge Heaters
Distributed Wattage
Style DW

Distributed wattage concentrates extra heat where it is needed. This is particularly useful to compensate for high heat losses along the edges of heated parts. Specify number of zones, zone lengths, and wattage distribution.
High Temp Cartridge Heaters
Multi-Zone or Three Phase Cartridge Heater
Style MZ

Flexible standard lead wire is crimped with a nickel connector to the end of the solid conductor and electrically insulate with 1-1/2″ of high temperature sleeving. Heater has 3 individually controlled heated zones or may be used as a three phase heater.
High Temp Cartridge Heaters
Style MD

Offering in 1/4" - 3/4", Heater cannot exceed 9.7 Amps. Threaded fitting is compatible with this model.
High Temp Cartridge Heaters
Stype MDB

Offered in 1/4" - 3/4", Heater cannot exceed 11.5 Amps. 1/4" - 3/4" cannot exceed 9.7 Amps. Threaded fitting is compatible with this model.
High Temp Cartridge Heaters
Style MDH

Offered in 1/4" - 3/4", Heater cannot exceed 11.5 Amps. 1/4" - 3/4" cannot exceed 9.7 Amps. Threaded fitting is compatible with this model
