E-rational 1000 series

BEP Europe through its Energy & Infrastructure Division – “E-Rational” 
is delivering a cost-effective solution to convert low temperature heat into clean energy power without emissions. Our state-of-the-art Organic Rankine Cycle (ORC) technology combined with the usage of industrial grade components makes E-Rational’s ORCs user-friendly, robust and economically viable.


E-Rational’s ORC machine has been designed for a maximized combined uptime and efficiency with a minimized operational and maintenance cost. This resulted in a skid-mounted modular machine, CE-compliant, with plug-and-play connections for easy installation.

The ORC-1000 machine absorbs up to 1,000 kW (3.4 MMBTU/h) thermal heat in a temperature range between 80°C and 150°C (176 F – 302 F). The ORC units are heat powered by hot water, thermal oil or low pressure steam coming from:

  • Waste heat flows from industrial processes, e.g. cooling cycles from chemical plants,  glass-,  steel-  & food- industry,  power plants,  etc …
  • Unused heat in District Heating networks
  • Biomass furnaces and CHP/COGEN or biogas installations
  • Geothermal wells


Depending on the operating conditions, E-Rational’s ORC-1000 series are offered with different types of expander-generator sets with typical outputs ranging from 55 kWe to 132 kWe.
