Etched Foil Heating Element

There are numerous advantage of etched foil heating element such as rapid heating, reliable and durability for almost every applications. It consists of etched foil resistive element which is laminated between two layers of insulation material. It can be shaped in any design and can be easily fitted due to its flexibility and design.

Etched foil heaters have standard sizing and can also be made to custom designs. Stock heaters include pail, drum, tote and gas cylinder heater as well as heat tapes. Some hard to heat application, however require custom heaters with flexibility, resistance to wear reliability and cost effectiveness. With no order minimum and the ability to choose material, size, voltage, wattage, cutouts, attachments options and built in controlling options. Etched- foil heaters are so personalized that virtually any application could be satisfied.
