Kanthal doubly wound tube furnaces

Kanthal doubly wound tube furnaces (8)

Main windings run the length of the core and controlled by the temperature controller, whereas the secondary windings, covering the front half of the core, are variable pitched, wound and controlled by an external variable transformer.
