History

1927 is the year in which Zenessis designs and produces the first generator set with a heat engine. Thus, with over 100 years of experience, Zenessis is one of the leading suppliers of generator sets.

With the passage of time, out of the need to provide clean energy solutions, Zenessis has developed a number of projects and products in the following areas:

  • Co-generation
  • Wind energy
  • Biogaz
  • Micro-hydropower plant
  • Solar panels
  • Uninterruptible Power Supplies (UPS)

Currently, for all its projects and products, Zenessis can provide:

  • Design
  • Research and development
  • Production and installation
  • Service and spare parts
  • Remote monitoring and efficiency
  • Funding projects.


For Zenessis to know how to provide viable alternative energy solutions is to succeed:

* assess the user’s consumption needs, production activities, taking into account the processes used, their size, as well as plans for further development
* identify natural or alternative energy supply resources, including resources generated by the user’s own activity
* identify and optimise possible energy exchanges with the distribution grid
* to optimise the user’s technical and human resources, as well as raw materials, in order to achieve the lowest possible production and maintenance costs.
Zenessis has managed to implement all the listed criteria in its development policy and therefore offers its customers professional solutions in energy production and management.
