    Spiral electric heating elements consist of cylindrical spirals formed by one or two resistive wires of suitable alloy depending on the application.
    Its main features include the inclusion of a nickel-chrome alloy wire heating element and a normalized tension of -230 V.
    The usual applications are: industrial dryers, air heaters, stoves, etc.
    Moreover, and according to the alloy wire they contain, we can distinguish three types of models:

    • M models, with a 20-5 quality and mainly intended for stoves.
    • MS models, with a 80-20 quality and useful for all applications.
    • MC models, with a 20-5 quality and used in quartz and infrared tubes.
