Marathon cartridge heater exceeds the performance and durability of other cartridge heaters. Through refinements in the swaging process, specially designed cores, careful selection of magnesium oxide fill, nickel chromium resistance wire, stainless steel tubing, and carefully controlled production processes, cartridge routinely outperform other cartridge heaters in difficult applications.

Cartridge are available in a wide variety of diameters and configurations. Choose from our large selection of stock heaters for immediate delivery or let FC Service people design a unique heater for your special application. Standard manufacturing times are normally less than 2 weeks.
Cartridge are UL recognized, File #E202904
and CSA certified, CSA file no. LR 109455-1

crimpedCrimped-On Leads
A high temperature double crimp connects the TGGT (450C) leads to solid nickel pins. This construction is recommended for applications with elevated temperatures. Due to the rigid nickel pins,. this construction is not recommended in applications where movement or flexing is encountered, or if sharp bends are required adjacent to the heater exit.

 

swagedSwaged-In Leads
High temperature TGGT (450C) wire is internally connected and swaged in place. This construction is recommended for applications in which the leads must be bent at the exit point from the heater and where mild lexing may be found. For applications with continuous or more severe movement, we would recommend metal braid or armor cable.

 

Stainless Steel BraidStainless Steel Braid
High temperature TGGT (450C) wire is internally connected and swaged in place. This construction offers protection against abrasion and sharp edges. This is a very strong construction which offers full length flexibility. this construction is recommended in applications with flexing and where the leads must pass through metal openings or routed along metal components.

 

stainless_hoseStainless Steel Conduit (Armor Cable)
High temperature TGGT (450C) wire is internally connected and swaged in place. This construction is recommended for applications in which the leads are subjected to abrasion or run the risk of being pinched. this is the strongest lead protection available and works well in moving or flexing applications.

 

Right Angle
Right Angle Fiberglass Leads
High temperature TGGT (450C) leads exiting at right angle to the sheath. This construction offers a compact design where space is limited. This construction is not recommended where abrasion or flexing is present.

 

Right AngleRight Angle Stainless Steel Braid
Stainless steel braid over high temperature TGGT (450C) wire exiting at right angle to the sheath. This construction is recommended in applications with flexing and where the leads must pass through metal openings or routed along metal components. This construction is desirable when space is limited and it is not feasible to bend standard leads.

 

Right Angle Stainless Steel ConduitRight Angle Stainless Steel Conduit
(Armor Cable)
Stainless steel hose over high temperature TGGT (450C) wire exiting at right angle to sheath. This is the strongest lead protection for use in applications where severe abrasion is present. These leads offer good flexibility and are good for moving or flexing applications.

 

Single or Double Threaded FittingsSingle or Double Threaded Fittings
Single or double threaded fittings attached to sheath to allow for installation into threaded holes.

*Fitting Materials
– Brass, Steel and Stainless Steel

*Leadwires
– Fiberglass for high temperature applications
– Teflon for moisture protection
– Stainless Braid or Hose for flexing applications
and abrasion protection.

*Terminal Boxes
– General purpose and moisture resistant housing

 

Mounting FlangesMounting Flanges
Mounting flanges are recommended for applications where vibration or movement may cause the heater to be dislodged from its hole. Stainless steel flanges are available in a variety of sizes and configurations. The standard flange is round and is supplied with two mounting holes. For heaters 5/8″ diameter and under, the flange would be 1 1/2″ in diameter. For larger diameter heaters the standard flange would be 2.00″ in diameter.

 

teflon_end_sealTeflon End Seal
A Teflon plug is swaged in place along with Teflon leads. This construction resists oil and water to 250C/480F. There is a minimum of a 1.00″ unheated length at the lead end. Longer cold sections may be required if the watt density or operating temperature is high.

 

Post terminalsScrew Terminals
Threaded stud terminals are supplied complete with high temperature nuts and washers. Standard screw is #8-32. Available in 5/8″, 3/4″, 1″, 16 mm and 20mm diameters heaters.
*Available Terminations
– Solid nickel pins
– Leadwires
– Threaded studs

 

Terminal BoxesTerminal Boxes
Terminal boxes are permanently attached to the heater sheath to provide excellent protection in a variety of environments.
Available Boxes
– General purpose sheet metal
– Moisture proof
– Cast aluminum explosion resistant

 

Double Ended TerminalsDouble Ended Terminals
These terminations are ideal for applications where wiring form both ends is required. A minimum cold section of 1″ is required for these leads.

Why High density Heaters:

Higher watt permit smaller heaters to be used without lose life expectancy, the result up-front money saving.

No vibration and shock damages due to swaged construction.

Excellent heat transfer.

Heater allows customization to any application.

cartridge-heater-thermocouplesInternal Thermocouples
Internal thermocouples are built into the heater assembly to monitor the internal or sheath temperatures. These are useful as high limit devices or in applications where space is at a premium. The power and sensor leads exit the sheath together and can be ordered with a variety of lead protections. Not all thermocouple configurations are available on smaller diameter heaters. Type J and K calibrations are standard for the shown constructions.

Grounded at Center
The thermocouple junction is grounded to the sheath along the length of the heater. The standard location is at the center of the heater, but can be located anywhere along the length of the sheath. This construction will provide a quick response.

Ungrounded at Center
The thermocouple junction is ungrounded and is centered in the diameter of the sheath. The standard location is at the center of the heater, but can be located anywhere along the length of the sheath. Typically used as a high limit in air or vacuum applications.

Grounded at Disc End
The thermocouple junction is grounded to the disc end of the heater. This construction is commonly used in hot runner applications. The disc end can be filled with silver solder and ground flat. This will ensure good contact when inserted into a flat end blind hole.

Ungrounded at Disc End
The thermocouple junction is ungrounded and is located just behind the disc end. This will give a reference temperature of the part being heated.
