2010 to 2012 – Foundation
Enerbie GmbH was founded in 2010 with the aim to developing very small (approx. 10kWe) ORC modules as a ready-to-use container solution. The heat source for these micro-ORC plants should be exclusively waste heat (T<= 180 °C) from industrial processes. In the course of this, a series of design and calculation tools were developed, which to this day serve as the basis for all thermodynamic turbine designs and cycle calculations.
Parallel to the in-house development activities, engineering services were continuously offered on the basis of work contracts. The hermodynamic design programs for ORC turbines developed in house were used for renowned industrial customers and formed the basis for successfully implemented turbine projects.
2013 to 2017 – Further development of the foundation and growth.
Since 2013, Enerbie has also been active as an engineering service provider in sealing technology in addition to thermodynamics, turbomachinery and plant engineering. Here, too, Enerbie has built up a very high level of expertise, so that today it is actively involved in the DIN EN 1591 1 standards committee, among others, and is thus helping to shape how tomorrow’s sealing tasks will be tackled.
Parallel to the continuous development of the internal design and calculation tools, the use of FEM (Finite Element Method) and CFD (Computational Fluid Dynamics) as a daily tool to support analytical calculations was cultivated more and more.
At the beginning of 2014, the one-man company became a team with the addition of Dipl. Ing. (FH) Till van Lück, an expert in turbine construction. Also based on the resulting newpossibilities, a third-party ORC turbine in South Tyrol was successfully upgraded in 2015 together with a partner company. The ORC plant efficiency was increased by almost 20% through the use of the newly designed and constructed components supplied by Enerbie. In addition, the running smoothness and vibration behavior were greatly improved by ensuring a very high manufacturing quality of all components, good balancing and careful assembly.
In 2016, “Madyn 2000” was acquired as a further tool for solving rotordynamic tasks (lateral and also torsion analyses) and integrated into the calculation activities.
In total, Enerbie is now able to process and solve all questions and problems relating to the conception, detailed design, manufacture and operation of turbomachinery in-house.
In 2017, the team was expanded to include Dipl. Ing. (FH) Ralf Diekmann, also an expert in turbine construction, and Heike Rötger (accounting).
2017 to 2020 – Preparation for new
At the end of 2019, a commercial property with just under 1000 m² of usable space was acquired near the old company headquarters. The relocation of the office and the establishment of the manufacturing and assembly area was completed at the beginning of 2020, so that in the future, in addition to engineering services, more component and manufacturing-related services can be offered.
2021 to date – repositioning
After a good 10 years in business, Enerbie is now approaching its original founding objective – the design and manufacture of steam turbine plants. In the field of ORC turbines, a modular system with four sizes has been developed for this purpose, covering a power range from approx. 120 kW to 2500 kW electric. Smaller and larger individual outputs or tandem and twin configurations, as well as the use of special media as working fluids, are possible.
