Curved Graphite Heating Elements Optimize System Responsiveness

Our patented* GraForm curved graphite heating elements for VFS model furnaces represent a major breakthrough for the thermal processing industry. Because GraForm elements (left photo) are considerably thinner than conventional straight graphite elements (right photo), they have a lower mass. This delivers a very responsive system with operational consistency. These high density elements, in most cases, surround the work load 360° for excellent temperature uniformity.

These are the advantages of GraForm heating elements:

Considerably thinner (typically 1/8" thick) and have less mass than conventional graphite heating elements
Just as stable as conventional graphite heating elements
Can be installed in most furnaces with conventional circular hot zones
Segmented design makes repair and replacement easy and economical
Utilizes the same power supply as provided with the existing moly elements
Less costly to install and easier to repair than traditional straight-segmented graphite elements

Graform heating elements are available on all horizontal VFS furnaces up to 74" element diameter.
