Highlights of the SGT-A05 (Industrial 501-K)

The SGT-A05 is proven to operate in various challenging conditions and locations around the world, including the North Sea, West Africa, Siberia, Brazil, Alaska, Southeast Asia and the desert regions of the Middle East. The SGT-A05 engine has been shock-qualified to Mil-S-901C, which makes it particularly suitable for areas with frequent or severe seismic activity.

The SGT-A05 is known for its high fuel flexibility, which will accommodate a wide variety of possible application scenarios and requirements. Fuels include, but are not limited to natural gas, liquid fuel (or both) and mid to low BTU gas fuels. Fuel system options include dual fuel, steam and water injection. Dry Low Emissions (DLE) technology is also available.

Thanks to advanced engineering, the SGT-A05 gas turbine provides fast start-up capability: You will have full power available within 60 seconds in all conditions. This includes hot restarts, with no need to go into idle condition. The SGT-A05 engine also offers black start capability.

Three popular, proven combustion systems that enhance profitability are available, based on your needs:
- Standard combustion systems operate on liquid or gas fuel
- Wet low emissions combustion systems utilize nozzle steam or water
- Dry low emissions combustion systems for gas-fueled installations achieve emission levels of 25 vppm NOₓ and 50 vppm CO

Complete customer care for the SGT-A05 gas turbine

Our comprehensive portfolio of services provides low life cycle cost and optimum performance throughout the turbine’s life cycle: Long Term Programs (LTP), overhaul service, field service, spare parts, service exchange, remote diagnostic service, and modernization and upgrades.

The modular, compact design of the SGT-A05 facilitates on-site maintenance, since the modules can be quickly replaced.  A direct core engine exchange is possible and can be executed in as little as 12 hours. The proven lightweight industrial design allows an easy and economical transport. 

  • Simple, inexpensive to maintain
  • Rugged, reliable performance with up to seven years baseload duty between full overhaul
  • Over 98% demonstrated availability/reliability
  • Lightweight and aeroderivative design

Reliable, easy installation and maintenance

Easy on-site maintenance due to core engine or module replacement.

Long maintenance intervalls

The SGT-A05 demonstrates reliable performance with up to 7 years of baseload operation between major overhauls.

Fuel flexibility matters

The SGT-A05 engine is designed to operate on a wide variety of fuels.
Fuels include, but are not limited to, natural gas, liquid fuel (typically DF-2 or equivalent) and mid to low BTU gas fuels. Fuel system options also include dual fuel, steam and water injection. Dry Low Emissions (DLE) technology is also available.

  • On-skid fuel system: The on-skid fuel system includes all components needed to control fuel during start up and operation
  • Clean, flexible operation: The SGT-A05 DLE combustor burns a great variety of gaseous fuels and offers clean combustion with low emissions. The engine, equipped with WLE burners, is capable to burn up to 15 vol% of hydrogen (H2).

Low emissions as a gateway to our customers

The well-proven and reliable Dry Low Emissions (DLE) system offers clean combustion for gas-fueled engines with low emissions for power generation applications. It achieves emission levels of 25 vppm NOₓ and 50 vppm CO. The Wet Low Emissions (WLE) system utilizes nozzle steam or water injection for liquid-fuel operation in order to meet the most stringent environmental requirements.

  • Clean combustion at flexible load: The proven standard combustion system can be operated on liquid or gaseous fuel, or with a dual-fuel option providing low emissions at part and base load.
  • Advanced lean-burn combustion technology: The Dry Low Emissions (DLE) engineering solution reduces emissions without the need for water injection.
