IDHELIO accompanies you throughout your projects and your reflections to decarbonize your industrial processes.


Before any project, we carry out a first opportunity study free of charge.

It allows to quantity the usefulness of an IDHELIO installation on your existing system or for a future realization.


It includes an hourly energy balance, a study of the settlements and interfaces with the industrial process, and a comparative analysis of different technical solutions.
It allows an optimization of the dimensioning, and the establishment of the specifications.


Once the profitability of the project has been studied, IDHELIO can advise you and guide you in setting up its financing scheme.
