Cartridge heaters
Cartridge heaters are primarily used to heat solids, and are also successfully applied to liquids and gases. Their design enables very high power density from a compact footprint, allowing installation where space is limited.
They are ideal wherever fast, precise heating is required – for example in forming dies, punches, injection nozzles, sealing jaws and knives, molds, edgebanders, and small tanks.
Their sealed construction resists dust, moisture and contact with process media. Each heater is engineered for a specific application, tailored to the bore and required operating parameters.

Specification
Optional integrated temperature sensor:
- Thermocouple type J (up to 650°C)
- Thermocouple type K (up to 1000°C)
- Pt100 RTD (up to 350°C)
The specified temperature refers to the sensor’s maximum operating temperature, not the heater.
Type A – Flexible lead outlet; leads can be bent directly behind the heater. Option: additional cable protection.
Type B – Rigid rods extend from the heater; leads attach to rods (cannot bend directly behind the heater).
Type C – Side outlet directly from the heater body; very compact angled outlet for tight spaces.
Type D – Angled heater with terminal block; highly sealed and mechanically protected outlet.
Type E – Angled heater with welded sleeve; same diameter as the heater for tighter installations.
Type F – Heater with threaded bushing (dimensions and position per specification). Variants: F1, F2.
Type G – Single‑pole lead outlet (low‑voltage only).
Type H – Single‑pole stud outlet (low‑voltage only).
Type I – Straight heater with stop/mounting flange.
Type J – Straight heater with welded mounting bracket.
Type K – Bent cartridge heater.
Lead options:
- PTFE‑insulated leads (optionally ultra‑flexible SIFF) – max 250°C (SIFF 180°C)
- Fiberglass braided leads – max 350°C
- Fiberglass sleeved leads – max 350°C
- Conduit‑protected leads – max 350°C
- Stainless‑steel braided leads – max 350°C
- PTFE leads in sleeve – max 250°C
We can tailor the power distribution along the heater to control temperature precisely. Lower winding density in the middle shifts more heat to the ends; higher density in the middle concentrates heat centrally. This reduces end losses or targets specific zones.
