Elements suitable for heating metal surfaces. They provide for an even distribution of the temperature on the whole surface of the equipment thus  avoiding any possible thermal expansion and allowing at the same time to exploit the power delivered with maximum efficiency. The heating element  can be easily fastened to the mass with the help of an adhesive film and provide an optimal heat exchange. The possibility to produce elements with custom measures make them suitable for a large number of applications. Possibility also to produce them complete with thermal sensors (thermostats, thermocouples, PT100)
