Etched Foil Heaters
Etched foil elements are used for heating surfaces and fluids through excellent heat exchange and thermal uniformity, generally with lower temperatures than those on other heaters. Etched foil heating elements come from printed circuit technology. These heaters comprise of a slim metal heating track (in aluminium, steel, nickel-chrome, non-magnetic alloys, copper, etc.) between two insulating sheets of silicone, polyester, polyimide or mica and supplied complete with wires with PVC, silicone, polyimide, Teflon, etc. protection.
