Split Sheath Cartridges Heaters
Split sheath cartridges heaters complement traditional cartridge heaters. Successive cleaning can degrade the holes, enlarging the original hole.
This technology makes it possible to fill these spaces in order to ensure uniform heating.
By expanding, the 2 parts of the metal sheath of the cartridge move apart, conforming to the walls of the hole and thus maximizing heat transfer.

During cooling, a retraction phenomenon occurs, returning the heating element to its initial state.
The split sheath cartridges heaters also prevent seizure during their extraction, in particular for very long holes, making it easier to maintain . They are made to measure according to your needs and dimensional constraints.

Split Sheath Cartridges
Unlike traditional cartridges heaters for which we recommend an H7 bore, split cartridges are intended for irregular bore holes.
This technology allows uniform heating over the entire length of the shielding, without a non-heating zone at the bottom of the cartridge.
Main characteristics :
- High quality magnesia insulated heating wire
- Metal shield in incoloy , folded in on itself and strongly compressed.
- Connection by wires or threaded terminals.
We can produce split sheath cartridges heaters with specific temperature profiles, strengthening the power of certain areas.
They can also be equipped with various connectors and specific accessories: thermocouple, wire guide to prevent any untimely tearing, fixing flange, etc.
Split sheath cartridges heaters are custom made to your specifications. Below is a summary of the main technical data: This list is not exhaustive, do not hesitate to consult us.
- Incoloy sheath, metric range from 8 to 25 mm , in imperial range from 1/4 “to 1” .
- Length: from 38 mm to 1525 mm , depending on the sheath diameter
- Standard connection by glass silk insulated wires (optional: beaded wires, high temperature wires 450 ° C, etc.), threaded terminals, mechanical protection of the supply wires (braid, flexible metal sheath, etc.)
- Optional reinforced sealing to prevent material penetration.
Features applicable to split cartridges:
- Power tolerance: -5% / +13%
- Our products bear the CE marking because they comply with Directives 2014/35/EU (Low voltage / LVD), 2014/30/EU Electromagnetic Compatibility (EMC) and 2011/65/EU ( RoHs ) (+2015/863/EU modifying the Annex II of Directive 2011/65/EU)
- Complies with REACH regulations
Products associated with split cartridges, to power them, regulate their temperature and accessorise them:
- Cables (power supply, thermocouples) & accessories (sockets, connectors ….)
- Temperature sensors (thermocouples, PT100 probes)
- Temperature control (electrical boxes, regulators, thermostats, etc.)
