Aluminium Foil Heater

Electric resistance heaters with foil backing are being produced to fulfil specific specifications for size, shape, layout, cut-outs, lead wire, and lead termination. The heaters can be provided with dual wattages, dual voltages, built-in temperature control, and sensors. The aluminium foil heaters can be mechanically affixed with rivets, sheet metal screws, or other mechanical devices, or they can be mounted to a surface using an integrated adhesive. For more demanding applications, a semi-rigid aluminium backing plate delivers structural support.

The aluminium foil heater has moisture resistance and is very low-cost compared to other heaters. It can be easily installed with an adhesive blocking system, and the highly flexible and high thermal conductivity of aluminium foil makes it possible to regulate the temperature quickly. For the power supply, a 3.5 (customizable) meter cold lead with XLPE or silicon insulation and PVC sheathing is used. It uses high-grade aluminium foil that can sustain a temperature range of up to 650°C. Furthermore, the temperature of the cable will be maintained at 150 °C for continuous operation. Temperature can be controlled using thermal regulators (thermostats).
