Cartridges and coil heater



Our Cartridges are made to your specifications. We use stainless Steel 321 which provides for better heat transfer. We carry a variety of cartridges in stock.

We offer a variety of cartridges for the packaging industry which will improve energy efficiency by 25%.

About Cartridges

✓  Packing (sealing)
✓  Extrusion, plastic injection
✓  Metallic masses heat
✓  Mainly industrial environment

•  Available in Metric and Imperial diameter sizes
•  Voltage: 120V to 600V single or three-phase


•  Cartridge Heaters with dimensional tolerances
•  Wattage, Teflon, GE on → profile heating on request
•  Expoxy sealed for humid environment (environnement humide)
•  Anti-seize → Teflon for easy removal
•  Ground wire
•  Integral thermocouple (J or K)

1Cartridges (more globally all heating elements), have to be stored in a dry place because humidity is the 1st cause of troubleshooting when installing. To ensure a long life for your cartridges, they must be heated to 250�F or 121�C for 30 min before installing them to remove humidity.

2Do not exceed the WATT density of maximal recommended power :
•  Low density : 45 watts and less per 2"
•  Medium density : 40 to 65 watts and less per 2"
•  High density : 65 to 160 watts and less per 2"

It is recommended to lower the wattage of your cartridges by 20% for applications requiring a certain amount of motion.

3Ensure that the hole in which you insert the cartridge is cleaned and has the right diameter.

Exemple : a 5/8" cartridge has a tolerance of 0,01 to -0,05 mm on the diameter, given that it expands when heated.

4Contamination lowers the lifetime of a cartridge. Cartridges can be sealed at one or both extremities if required for environmental purposes.

5Choose Teflon wires instead of fiberglass wires if the operating temperature is below 500�F or 260�C.
The teflon wires have a longer life and protects against humidity.

Coil heaters


Coil Heaters are designed to reach high temperatures on a reduced surface by direct contact on varied forms. They are easy to install and remove, plus coil heaters are completely sealed.

✓  Molding by injection for parts with thin walls
✓  Packing
✓  Nozzles with stick and small nozzles that requires high temperature
✓  Flat cylindrical parts or particular shapes
✓  Pipe heaters

•  Nickel-chrome resistance wire in a SS321 stainless steel sheath, also available in brass
•  May be round or flat → (A flat coil ensures better heat transfer)
•  Mini coil heaters are also available round or flat
•  Voltage: 120V to 600V Single phase
•  Choice of lengths of heated and unheated zones
•  Fiberglass leads are standard. Protection such as braided metal sleeving, teflon or armor cable are available on request


•  Integrated Thermocouple Type J or K
•  S/S Strap offered on Mini Coils
•  Ground Wire
•  S/S Braided Leads
•  The coils can be made flat and then formed to your specifications.

1Do not fold any area already folded and do not force the shaft into a bent position → (cold part of the element).

2A new straight fold needs to have a minimum �" radius → (Folding too squarely could damage or break the element).

3The coil heater needs to be positioned in perfect contact metal against metal with the part to be heated to avoid any air pockets that could easily burn the element.
