Energy efficiency services

Energy-efficient processes not only protect the environment, but also your wallet!

Due to the everyday stress in production, you often lose focus on energy efficiency within the processes. Here, competent advice can often reduce up to 30% of the energy costs in a company, most of it with little or no investment.


In a free preliminary talk we can get a rough overview of your processes and show how much potential we see.


Does everything suit you here? Then we come by again personally to take a close look at all the processes and record the corresponding values. We work out the strengths and weaknesses of your processes, look for potential and activation options for this potential and present our results.


If you wish, we can continue to support these projects with you.


Other services in this area are:


  • Seminars for energy-efficient production
  • Advice on the implementation of renewable energies
  • Calculation and simulation of processes

Didn’t find anything suitable?


We are also happy to help you with other engineering questions, be it calculation and simulation for non-energy processes or dashboard creation for other areas. Thanks to our competence with programs such as Matlab/Simulink, Microsoft Excel or Power BI, together we will find the optimal solution for your requirements!
