Flexible tubular heating elements RHK-F

The RHK-F flexible tubular heating element from Mickenhagen impresses with its simple handling. It can be easily bent in all directions by hand and installation in a groove is also very simple, e.g. with a rubber mallet. This opens up completely new possibilities for the designer when it comes to heating three-dimensional contours. The optimized design of the flexible tubular heating elements from Mickenhagen guarantees very good mechanical strength and optimum heat transfer. Different cross-sections and lengths are available at short notice.
