Mica heating strips

Heating elements of a cylindrical shape with the heating part formed by mica plates wrapped with a flat heating strip. The unit is enclosed in a stainless steel case and clamped with an external clamping sheet metal. This solution excels with small design thickness and allows for a significant range of resulting product dimensions while preserving sufficient mechanical strength. The heating strips of this type may be single- or multipart, with various power variants. They may be equipped with various variants of structural elements.
