About us

DB Energy is a leading company in the energy efficiency improvement sector which provides complex consulting and manages investment projects for large- and medium-scale industrial plants. For 11 years we have implemented more than 1200 energy efficiency projects which has generated the investments of more than PLN 4.8 billion. It has also contributed to the reduced energy consumption by 8,3 TWh and accounted for our clients’ savings which have reached approximately PLN 1,7 billion annually.

Within the INDUSTRY 4.0 program we have been implementing an R&D project for an innovative system called DiagSys whose aim is to detect incipient malfunctions in electronic motors. The system allows energy consumption of the machinery to be reduced by up to 7.5%. Since the system is compatible with IT solutions of BIG DATA, it is able to monitor industrial processes which, in consequence, is crucial for intelligent production plant management. It also makes it possible to assess the correct workflow of such components as electric drives, i.e. pumps and fans.
