Industrial waste heat
Boiler exhaust, furnace flue gas, kiln and dryer exhaust, engine jackets, and process hot streams.
ORC Technology
Organic Rankine Cycle systems for low and medium-grade industrial heat.
Datre's ORC technology converts residual heat into electricity using a closed-loop organic working fluid cycle suited to heat sources that conventional steam systems may ignore.
What Is ORC?
A familiar power cycle redesigned for lower temperature heat.
A steam Rankine cycle uses water. ORC uses a selected organic fluid with a lower boiling point, allowing power generation from lower temperature heat streams found in industrial exhaust and process systems.
This makes ORC useful for distributed generation close to the point of energy use, where factories can recover power without changing their main production process.
Research from the U.S. Department of Energy describes industrial waste heat as a major energy-loss opportunity, while ORC suppliers such as Turboden position ORC for waste heat, biomass, geothermal, solar thermal, and engine or turbine exhaust applications.
Where ORC Fits
ORC is strongest where the heat is continuous, recoverable, and too low for steam.
Biomass and geothermal
Distributed power generation where steady renewable heat is available near the point of use.
Engines and gas turbines
Bottoming-cycle recovery from exhaust streams that still carry usable thermal energy.
Closed-loop operation
The working fluid loop is separate from the plant process, making integration easier to plan.

How The Cycle Works
Five steps, continuously repeated.
- Heat InputWaste heat from exhaust gases or process streams enters the evaporator.
- EvaporationThe organic working fluid vaporizes under controlled pressure.
- Expansion & PowerHigh-pressure vapor expands through the turbine and drives a generator.
- Heat RecoveryA recuperator can recover remaining heat inside the loop when the project design calls for it.
- CondensationThe expanded vapor cools and returns to liquid state through air or water cooling.
- Pumping & RepeatThe liquid fluid is pumped back to pressure and the cycle repeats continuously.
Datre Advantages
What should separate Datre from global ORC players.
Indigenous Turbine Design
The turbine and expander are the core of ORC economics. Datre positions domestic turbine development as the heart of its engineering advantage.
Low-Temperature Focus
Prioritize the 90°C-200°C industrial range where many boiler, dryer, and process exhaust streams sit.
Working Fluid Selection
Match the fluid to each heat source to improve practical energy recovery and operating stability.
Lower Parasitic Load
Design pumps, fans, controls, and heat exchangers so the system keeps more generated power available for the plant.
Patented Circuit Wording
Publish the exact patent claim only after status is confirmed: filed, pending, granted, or licensed.
Scalable Architecture
Use the same engineering base from 10 kW trials through 50 kW pilots, 500 kW modules, and larger custom projects.
