Optional Energy Saving System ESS (Energy Saving Systems)

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

The system controls the operation of the hydraulic pump motor via a frequency inverter, adjusting the motor’s rotational speed to the current demand during the production cycle. As a result, electrical energy is consumed only during the actual machine demand.

Key Advantages

- Up to 30% reduction in electricity consumption
- Servo drive technology for the hydraulic pump
- World-class and proven technology used in the plastics processing industry

- Reduction of energy losses during idle operation
- Lower heating of the hydraulic system
- Longer service life of hydraulic components
- Possibility of installation on existing hydraulic injection moulding machines

The ESS system enables a significant reduction in machine operating costs while maintaining full production parameters.
