JSJ Jodeit distributors and forehearths are designed as rectangular cross-section channels for the operation of small and medium pull rate. The distributors are connected upstream of the forehearths. The forehearths provide subsequent forming processes with thermally and chemically homogeneous glass melt while maintaining the required high temperature stability.

Special water-cooled molybdenum electrodes are installed through the superstructure of the distributors and forehearths. The necessary energy is supplied via these electrodes by passing current directly through the melt. The electrodes are connected in several heating circuits that are operated in a temperature-controlled manner.

Drains installed in the bottom ensure the removal of corrosion products of the refractory material and thus a very good chemical homogeneity.

If required, specially designed stirrer systems are provided which further improve the thermal and chemical homogeneity of the melt.

Furthermore, radiometric glass level measurements can be installed alongside the distributor or forehearth. Special start-up electrodes are installed at the bottom of the distributors and forehearths.
