ORC Turbines


Low RPM of the turbine allowing the direct drive of the electric generator without reduction gear

Product details

More Information on ORC Turbines

ORC Turbines is used for distributed generation in renewable and heat recovery. This technology enables:

  • High turbine efficiency (85%)
  • Low mechanical stress turbine (due to low tip speed, moderate temperature)
  • Directly driven generator (no gearbox)
  • No blade erosion (due to no liquid particles)
  • No oxidation (metal friendly working fluid)

The advantages:

  • Simple start-stop procedures
  • Automatic, unattended operation
  • Quiet running
  • High Availability (>98% proven)
  • Turn-down to 10% of nominal power
  • Good efficiency at partial load
  • Long life
  • High efficiency with low / moderate temperature sources
  • No boiler feed water treatment
  • Minimum O&M: 3-5 hours / week
