The already successful series of TF granulators is improved by a new lower version with traction unit and dancing arm that can be installed under the conveyor belt and / or stacker of the modern thermoforming machines. Its maximum height is 890 mm, compared to 1085 mm of the standard version, mantaining the same productivity and meeting once again the most strict ergonomic requirements. The soundproof box is fixed to the ground and it is made with reinforced thickness (80 mm); the granulator is extracted from the box using a useful trolley that allows then the handling between different departments. The electrical panel and the control keypad can be positioned as needed depending on the necessity of each customer. Furthermore, this machine maintains the ease of maintenance (screen-holder and traction unit access) of the range to which it belongs.
