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
