Revolutionary Turbo-alternators:
- High speed, 45,000rpm; minimises the size
- Gas foil bearing technology; long life with high reliability and oilless system. No bearing ancillary equipment
- Integrated hermetically sealed turbine and alternator; eliminates potential for rotating shaft seal leaks and improved efficiency
- Stator and bearing cooling using the working fluid; no ancillary cooling.
- High Frequency AC alternator; single shaft with turbines eliminates coupling inefficiencies
- Unique twin turbine minimises thrust bearing loads
- High temp (170kW) & Low Temp (60kW) available
High Speed Electronic Drive (AS4777 & IEC62109 certified) :
- Customised to gTET’s HFAC Turbo-Alternator, 750Hz.
- Turbine control non-synchronous and independent to grid.
- Manages regulatory requirements for grid connection
- Provides variable speed drive for ORC pump and cooling tower pump and fan
- Electrical load is customised in software to match the turbo-alternator performance for maximum efficiency while protecting the turbine.
- System turn-down by 90% to match fluctuating heat source
