Optional ESS Energy Saving System (Energy Saving Systems)

The machine can be equipped with a state-of-the-art ESS servo drive system, which significantly improves the energy efficiency of hydraulic plastic injection moulding machines.

The system controls the operation of the hydraulic pump motor via a frequency converter, adjusting the motor speed to match the machine’s actual demand during the production cycle. As a result, electricity is consumed only when it is actually needed.

Key Benefits of the ESS System
- Reduction of electrical energy consumption by up to 30%
- Hydraulic pump servo drive technology
- World-class, proven technology used in the plastics processing industry
- Reduced energy consumption during idle operation
- Lower hydraulic system heat generation
- Extended service life of the motor and hydraulic components
- Can be retrofitted to existing hydraulic injection moulding machines without modifications to the machine’s structure

The ESS system offers a modern solution to considerably reduce the operating costs of the injection moulding machine while maintaining full production capacity.
