Rank® Technology

Learn more about our Rank® equipment for Organic Rankine Cycles (ORC) and High-Temperature Heat Pumps (HTHP).

The high-quality, robust and efficient components provide our customers with various benefits that are maintained throughout the operating period of the machines, even operating at high temperatures.

Rank® low-rpm

Operation at low revolutions reduces the noise level, lengthens the service life, and improves reliability.

Rank® direct drive

Direct drive avoids the use of gears or pulleys, minimising the maintenance and increasing electrical efficiency.

Zero leaks

Our hermetic components eliminate the leakage of the working fluid, reducing maintenance costs and downtime and being more environmentally friendly.

Magnetic transmission

Magnetic transmission to ensure tightness and to reduce the possibility of leakage.

Rank® easy-connect

Electronics-free connection to the electricity grid at the required electrical quality conditions.

Flexible operation

Modular machines that can operate under a wide range of temperature and flow inlet and outlet conditions.


Our machines operate without the need for the human interface through an automatic, efficient managing system.


It complies with all safety regulations and minimises the risk of accidents.
