High performance in compact space


Coil heaters are available in rectangular cross section 2.2x4.2mm and various lengths. Coil heaters provide high-capacity electrical heating in the tightest instalation spaces at temperatures of up to 750°C on the sheath. The possibility of easy bending allows the use of the coil heaters not only in straight or coiled form, but in almost every geometrical shape. Integrated thermocouple enables precise temperature control. Coil heaters are available with various exits to suit respective application.
