Optional ESS Energy Saving System (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 operation of the hydraulic pump motor using a frequency inverter, which adjusts the motor speed according to the current demand during the production cycle.

Key Benefits

- Reduction of electricity consumption by up to 30%
- Servo drive technology for hydraulic pump
- World-class quality and proven industrial technology
- Reduced energy losses during idle operation
- Lower heating of the hydraulic system
- Extended lifespan of hydraulic components
- Can be installed on existing hydraulic injection moulding machines
