The heating elements are produced with a stainless-steel tube in which a resistive wire insulated with magnesium oxide is inserted. Various types of finishes are available, each of which designed for the specific type of application. For use in humid environments the heating elements are sealed by vulcanization with either standard or anti-cut silicone, thus ensuring high reliability over time. The main application sectors are air conditioning, refrigeration, automotive and transport, heating, food & catering and the domestic field.
