The Stirring unit has been developed to blend the glass inside the forehearth during the colouring process.
Taking into account the severe working conditions due to high temperature, special attention has been paid for selecting the materials, both for the steel supporting frame and for the moving parts subject to wear, in order to improve their reliability and to reduce as much as possible the maintenance
operations.

The mechanical unit is composed by the following:
· Steel supporting frame
· Manual lifting hoist
· Stirrer assembly
· Air cooling system
