How it works

Power from Heat

Diesel gensets convert only 40% of the fuel energy into electricity, the rest is wasted. Triogen’s ORC technology converts the exhaust gas heat into additional power and thereby reduces the fuel consumption of the genset by 5-8%.
Lower your carbon footprint and save fuel:

  • With a capacity of 170kW, a single e-box saves 300,000 liters of fuel per year
  • No interference with genset performance or mining production
  • Machine build on proven components and 700,000 operating hours
  • Made to withstand harshest conditions
  • Runs without supervision – remotely controlled

Our solution for:

Remote/ Off-grid mines

Triogen’s ORC is a perfect fit for industries reliant on diesel-powered generators especially where fuel is most expensive. The device is easy to transport due to the containerized design, runs without supervision and has remote online monitoring. Especially in remote areas the investment in an ORC will provide a payback time in less than 2 years!

1-5 MW Generators

Diesel genset convert only 40% of the energy input to electricity. The rest is wasted. With Triogen’s ORC this otherwise unused exhaust gas can be converted into usable power, which reduces fuel consumption. The exhaust heat produced by the generators (with 1-5 MW) is at the ideal temperature for use of an ORC, maximizing savings on diesel.

Energy efficiency goals

Triogen’s ORC does not need any additional natural resources and enhances energy efficiency. In addition to reducing the energy bill, waste heat recovery lowers the entire operation’s GHG aligning the operation with the UN Sustainable Development Goals regarding energy efficiency.

Our Product

The Triogen e-box is a turnkey, exhaust-gas heat recovery solution for your generator. It is applied to your existing generator without any major interference.
The Triogen ORC technology is based on the widely known and proven Rankine Cycle principle.
This elevates your generator, which produces the same amount of electricity while saving fuel.

The Triogen ORC is CE marked, it complies to:
• Lloyds’ Register
• The Pressure Equipment Directive (PED)
• The Machinery Directive (MD)
• The Low Voltage Directive (LVD)
• The Electromagnetic Compability directive (EMC)

About us

Triogen, a leading Organic Rankine Cycle (ORC) supplier, has over the past 15 years successfully incorporated world class heat recovery technology into a reliable standardized product.
Our dedicated team of passionate engineers has developed best in class solutions for various heat recovery applications for the international market. Recent developments specific to the Mining Industry empower genset operators to save with a single ORC up to 300,000 liters of diesel fuel annually (equivalent to an approximate 5-8% saving on a 1-5MW genset) while at the same time addressing the energy and environmental challenges of our planet and increasing sustainability.
Our vision is to make ORC technology a standard feature for every 1-5 MW generator, just like the turbo chargers success showed over the last 40 years.
Our ORC technology significantly reduces fuel consumption and emissions, and thereby contributes to making the UN Sustainable Development goals a reality.

Contact us


1.What is the lifespan of an e-box?

More than 15 years

2.Will production be interrupted in any way?

No, installation will not interfere with production

3.Is there a loss of electricity production over the lifespan of the e-box?

No loss of capacity observered

4.Do you offer a customer satisfaction/performance guarantee?

Yes, including a buy back guarantee!

5.How is the e-box shipped

In two 20″ shipping container

6.Where is the e-Box set up?

Idealy next to the genset. Exhaust gas is diverted by a new valve in the existing stack into the ORC heat exchanger and then released to the ambience.

7.Does an ORC affect the warranties of the genset?

The Triogen ORC is designed to operate within the back pressure permitted by the genset supplier. Therefore all warranties stay intact.

8.What happens, if there is too much heat for a single ORC?

Multiple ORCs can be operated in parallel smoothly.

9.Can several gensets feed into one or more ORCs?

It is possible to combine several engines to multiple ORCs. This allows to maximize fuel savings, as not all gensets are running all of the time.
