TechSim ORC Unit: Innovation for Efficient Waste Heat Utilization

13/11/2025

Introduction: Why ORC Technology is a Game-Changer

Energy efficiency and sustainability are key topics today. TechSim Engineering offers a solution that combines cutting-edge technology with an eco-friendly approach – a micro ORC unit based on the Organic Rankine Cycle (ORC). This turbine converts low-grade heat into electricity, paving the way for cost savings and emission reduction.


How Does the TechSim ORC Unit Work?

ORC technology uses an organic working fluid that evaporates at a lower temperature than water. This vapor drives an expander or microturbine, generating electricity. The remaining heat can be used for heating purposes, creating a combined heat and power (CHP) effect with an overall efficiency of up to 85–95%.

Key Benefits of the TechSim ORC Unit

  • High efficiency – combined heat and power generation.
  • Eco-friendly solution – utilizes waste heat with zero emissions.
  • Flexibility – compatible with various heat sources (biomass, solar, geothermal, industrial processes).
  • Low operating costs – compact and reliable system.

Technical Specifications

  • Electrical output: 1.5 kWe (up to 8 kWe)
  • Heat source capacity: 21 kWt
  • Inlet temperature: 100 °C
  • Overall efficiency: 85%
  • Recoverable heat: 18 kWt

These figures prove that even small-scale ORC units can significantly improve energy efficiency.


Innovation in Development: 3D Printing and Digital Simulation

TechSim leverages metal 3D printing for rapid prototyping and turbine shape optimization. This approach:

  • shortens development time,
  • reduces costs,
  • improves performance.

Additionally, Siemens Simcenter tools are used for CFD analysis, structural calculations, and rotor dynamics optimization.


Applications of ORC Units

  • Industrial facilities – recovery of condensation heat.
  • Community energy systems – electricity and heat for residential buildings.
  • Biomass and CHP – integration with biomass boilers.

Why Choose TechSim ORC Unit?

  • Energy savings and reduced CO₂ emissions.
  • Advanced technology using additive manufacturing.
  • Flexible solution for small and medium heat sources.

Conclusion

The TechSim ORC unit is the perfect choice for businesses and communities seeking to efficiently utilize waste heat and generate their own electricity. It combines ecology, economy, and innovation in one compact solution.
