Etched Foil Heaters

If you are looking for heaters that are efficient and powerful, you might want to consider heaters that are constructed using our etched foil technology. These heaters use a metal alloy foil that is etched into a circuit and laminated between two layers of silicone glass fibre material to generate heat. These heating foils are ideal for customers who need to buy in large quantities, as they have a lower unit cost in quantity and a longer lifespan.

The heat distribution within etched foil heaters is greater compared to the wire wound construction, as they cover more of the surface area and have a larger uniformed heat output. This increased area means an etched foil heater can handle higher power densities and has rapid heat up capabilities. This improves the performance and quality of the heating process. As a result, these heaters are suited to applications such as aerospace, medical devices, electronic enclosures and food service equipment.

Our Etched Foil heaters can be designed with bespoke shapes, dimensions and fixing methods. Customisable to suit applications with a broad range of voltages and wattages. In addition, sensors, limiters, and thermal fuses can be integrated to allow control and operation in a wide range of temperatures. Contact us to discuss the needs and specifications of your custom etched foil heating elements.
