No more sky-high electricity bills, thanks to the technology developed by Dopak
ESS – Energy Saving Systems
After several years of research and refinement, Dopak has launched ESS – Energy Saving Systems for hydraulic injection moulding machines. It’s an add-on controller for the hydraulic drive motor that functions as a servo drive.
ESS is available in two variants:
- ESS COMPACT – for small and medium injection moulding machines up to 300 t clamping force,
- ESS SMART and ESS ONE – for machines above 300 t clamping force.
The system can be installed on machines from different manufacturers, regardless of brand. Installation is quick – setup takes up to 2 hours – and if needed, ESS can be moved to another injection moulding machine with the same or lower motor power. The units are built on Siemens or Mitsubishi components, ensuring high reliability.
Measurable benefits
With ESS, companies can reduce electricity consumption by up to 40% and cut spending on hydraulic oil cooling, translating into tangible operational savings. Measurements are taken for each machine before and after installation to precisely verify the actual savings.
The financial benefits are complemented by an environmental gain – a lower CO₂ footprint – which helps many companies advance their sustainability strategies.
Success story – savings in practice
A plastics packaging producer implemented Dopak’s ESS on a hydraulic injection moulding machine with 2 × 250 kW drive motors. The results were visible almost immediately: ~PLN 125,000 in annual savings, two-year ROI, and a ~85-ton reduction in CO₂ emissions per year.
An additional benefit was an improved Power Factor (PF), enabling more efficient use of active power and reduced reactive power in the power supply system. The entire implementation went smoothly and did not require any interference with the factory automation systems, allowing production to continue without interruption.
Financing? No problem.
In cooperation with Siemens Leasing, Dopak offers flexible financing options, making the investment easier without straining your budget. In practice, the device starts working and saving from day one, and part of the generated savings can cover the leasing instalment. The rest stays in your company.
ESS is a proven solution that delivers measurable financial and environmental results. It’s a technology for enterprises that want to genuinely lower energy costs, increase machine efficiency, and meet sustainability goals.
Take the first step toward real savings now!
With ESS, you can reduce energy costs by up to 40%, and pay your leasing instalments from a portion of the savings – without adding pressure to your budget.
