Heating films with graphene nanotubes have been proven to be an economical, efficient and durable solution. Electrically conductive heating films with nanotubes feature a polyethylene film 8-150 cm wide and 0.35 mm thick with a conductive coating modified by TUBALL graphene nanotubes from OCSiAl. When connected to a standard 220 W power supply, the film generates heat. The power of such a heating system is 350 W/m2, while the service life surpasses 10,000 on/off cycles.
The fundamental difference between film heating and other anti-icing systems, such as, for example, a heating cable, lies in its high efficiency – the film is capable of heating a much larger surface area with the same power consumed. Heating films can be used both in industrial facilities for heating pipelines, tanks and electrical cabinets, and in architectural facilities for roof anti-icing, heating sidewalks, steps and ramps, and residential heating.
