Square Cartridge Heaters for Heating Plates & Hot Surfaces

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)
