Square Cartridge Heaters are perfectly suited for very thin plates. With a soft, malleable condition in stainless steel or nickel sheath they can be pressed into common milled grooves. In standard construction the max. temperature capability is 750°C. All sizes also available with integrated thermocouple and power distribution.
Our long-term partner DELTA-t-Hochleistungsheizelemente (high-performance heating elements) successfully uses these heaters in a variety of applications.

Advantages of Heating Plates with Square Cartridge Heaters
- Simple plate manufacture due to rectangular groove geometry, no deep-hole boring
- Simple heater installation by bending and pressing along the plate surface
- Complex plate geometries with bores and openings
- Optimal heat transfer due to 75% surface contact
- No casting with heat conductive compound
- Uniform temperature profiles due to thermally optimized groove layouts/power distribution and utilization of insulation plates
- high process temperatures (up to 450°C in aluminium, up to 700°C in stainless steel)
