Pressed-in elements

Customized tubular elements and optimal heat transfer


Traditional round tubular heaters can be bent in almost any required shape and pressed into grooves in steel, brass or aluminum bodies. The outer sheath fits tightly to the surface of the groove. This guarantees optimal heat transfer and long service life. Different geometry and dimensions, optimal thermal features, robust construction and low production costs are outstanding arguments for this type of heaters. Tubular heating elements are delivered in straight shape or bent according customers request.
