Grafotronic Choose Green

Hi³ is the first Grafotronic machine under our new Choose Green program

Grafotronic Choose green manifesto: Sustainability must be worthwhile, because the profitability of our customers must remain – while increasing sustainability and reducing the environmental footprint.

Grafotronic Choose Green combines sustainability and efficiency. With the new regenerating brake system, the Hi³ captures the braking energy and converts it into power – this way the HI³ is now approximately 30% more energy efficient.
