Optional Energy Saving System ESS (Energy Saving Systems)

The machine can be equipped with the ESS servo drive system, which increases the energy efficiency of hydraulic injection moulding machines.

The system controls the hydraulic pump motor via a frequency converter, adjusting the motor speed to actual requirements during the production cycle.

Key benefits:
- Reduction of electric energy consumption by up to 30%
- Servo drive technology for the hydraulic pump
- World-class quality and proven industrial technology
- Reduced energy loss during idle operation
- Lower heating of the hydraulic system
- Increased lifetime of hydraulic components
