Enquiry

The cold end of a bar shape heating element is normally located on the extension of the heating element, but the cold end of type M is designed to be vertical in order to support uses such as the installation of electric equipment and the requests to change the cold end structure. The distance between the heating element and the heating object can be adjusted easily. The same materials as in types E and F are used.
