Product Introduction
U-shape Mosi₂ Heating Elemen: The double-handle U-shaped design is the most commonly used type. In this configuration, the heating end is welded to the cold-end terminal, and the diameter of the cold end is twice that of the heating end. This specification is the most widely adopted and is typically installed in a vertical suspension arrangement. When placing a custom order, customers must provide the required heating-end diameter, heating-end length, cold-end length, and center-to-center spacing, among other parameters.
