Coil heater

Description
Coil heaters provide high flexibility and can be shaped to fit machine nozzles and ducts by spiralizing straight heating profiles and tubes. This heating method is widely used in semiconductor and printed circuit board production, the pharmaceutical sector, plastics processing, casting, packaging and laboratory equipment manufacturing.

Features
These coil heaters feature a stainless steel or nickel casing and are capable of surface loads up to 32 W/cm². Heat dissipation can be further improved by casting the coil into brass or copper. Optional housings with tension screws serve as reflectors and simplify mounting. Coil heaters are also available in straight lengths for custom adaptation. For precise control, thermocouples type J or K can be integrated optionally.
