Tubular heating elements (RHK) Typical Applications Tubular heating elements (RHK) meet nearly all heating requirements Characteristics • suitable for heating in nearly all media • tubular elements consist of a metallic tube sheath and an inner heating coil • tubular elements are filled and compacted with the electric insulation material magnesium oxide Heated length Length of tube Diameter and maximal length before bending Tube sheath materials Copper, steel, stainless steel, further alloys on request Maximum admissible tube surface temperatures Copper 250°C, steel 400°C, stainless steel 750-900°C Attention: The tube ends of the standard heating elements must not exceed a temperature of 200°C in continuous operation Unheated tube ends 30-800 mm (standard 50mm); tolerance on request Technical modifications reserved Eichenauer Heizelemente GmbH & Co.

Bending examples • The illustrations show examples of current shapes. C1 Bending recommendations • They are formed in cold state by means of bending rollers. • The terminal stud and heating conductor may not be connected in a bend. • For coils laying above each other, the diameter is not allowed to be less than 60mm. • The bending radius should not be less than the values given in the table below.
