Highlights of the SGT-750 gas turbine
The SGT-750 has the highest efficiency and power in its class combined with Dry Low Emissions (DLE). As a result, you can expect lowest lifecycle operating costs and the best possible return on investment. Even running on part load, the SGT-750 keeps the highest efficiency and at the same time an increased time between overhauls, with guaranteed emissions of 9 ppm NOₓ.
The combustor and burner designs provide you with a world-class emission performance over a wide load range and are capable of single-digit NOₓ emission levels. The SGT-750 can guarantee 9 ppm NOₓ down to a 20% load. Designed to reduce environmental impact, the SGT-750 gas turbine will help you meet even the strictest emission regulations worldwide.
The SGT-750 is the perfect option for power generation and offers a wide range of solutions, from stand-alone installations to complete power plants, industrial or oil and gas, onshore or offshore.
The fast start-up and cycling capabilities support intermediate to continuous operation. Lightweight and compact design allows for quick installation and easy maintenance.
We offer a full range of extended scope and turnkey solutions for mechanical drive applications. With decades of experience, we are able to design and implement any application, whatever the requirements are:
- Compressor applications (e.g., gas injection, gas processing, LNG, FLNG and pipelines)
- Pump applications (water injection and fluid transmission projects)
The SGT-750 features a specifically service-friendly design:
- Rollout for 24-hours gas generator swap
- Easy on-site or off-site maintenance designed for only 17 maintenance days in 17 years
- All components feature a modular design with best accessibility
- Easy access for borescope inspection
- IR cameras for early detection of possible deviations
The SGT-750 offers broad operational flexibility to satisfy your individual, market-specific requirements. With a twin-shaft design and a generic driver, you can use the SGT-750 in power generation or mechanical drive, onshore or offshore.
For example:
Highest performance at extreme conditions, from arctic to desert conditions, fast start capability, quick load variations like load rejections or instant loading, wide fuel range, roll-and-pitch capability and free power turbine are just some of the operational benefits.

Ingenious design to the core
The SGT-750 gas turbine is designed to meet the highest demands for efficiency, reliability, uptime and environmental compatibility.
The SGT-750 gas generator consists of a 13-stage axial air compressor with an EB-welded rotor for robustness. Two variable guide vanes in the compressor offer optimized performance even in the most extreme conditions.
The combustion system consists of 8 cans and 8 transition ducts. The system is suitable for both liquid and gaseous fuels and the design provides for outstanding ease of maintenance and exchangeability without casing disassembly.
The SGT-750 has a free 2-stage power turbine with a nominal shaft speed of 6,100 rpm. For mechanical drive, it can run at between 50 and 105% of the speed. The turbine can be optimized for all ambient conditions, from cold to hot climates.
Proven design principles thanks to profound experiences
The SGT-750 combines proven technology and state-of-the-art materials.
Compact design meets all customer demands
The SGT-750 gas turbine is designed as a robust and compact indutrial gas turbine combined with aero engine performance.
SGT-750 package
The SGT-750 is delivered as a complete package. The package is a module as carefully designed as the core engine. Supporting systems and customized solutions interact closely to create an entity that delivers secured return on investment.
The modular build-up facilitates swift disassembly and parts replacement, and with a 24-hour engine swap time, downtime can be kept to an absolute minimum.
All SGT-750 package options are available as single lift and share the same driver for mechanical drive and power generation which increases the operational reliability.
SGT-750 for power generation
The SGT-750's fast start-up and cycling capabilities support both intermediate and continuous operation with improved turndown capability.
SGT-750 for mechanical drive
With its twin-shaft configuration, the SGT-750 is driving compressors or pumps either onshore or offshore. Minimized starting power needed.
Offshore: roll and pitch
Small footprint due to compact design and highest availability – these are the best prerequisites for offshore applications as FLNG or FPSO.
The SGT-750 fires up
With maximized uptime, top-class performance, and a low environmental footprint, the SGT-750 industrial gas turbine offers you a high lifetime profitability and is a perfect choice for the oil and gas industry as well as industrial power generation.
Fast start-up and cycling capabilities support both intermediate and continuous operation.
We offer a wide range of solutions for power generation, from stand-alone installations to complete power plants for industrial and onshore or offshore power generation, and the oil and gas industry.

Excellent combined cycle and combined heat and power efficiency
The SGT-750 is your perfect choice for combined cycle power plants for base load, standby power and peak lopping as well as cogeneration applications with heat load and district heating schemes.
17 maintenance days in 17 years
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.
Serviceability and maximized uptime have been a top priority during the development of the SGT-750.
With 68,000 equivalent operating hours (EOH's) to first major overhaul and a service plan with only 17 maintenance days in 17 years, the SGT-750 offers highest operational availability. On-site or off-site maintenance are the two alternatives of executing planned service. There is no need for special workshops. When operating on lower loads, the time between overhauls can be easily increased by thousands of hours.
All models of the SGT-750 are mapped with infrared cameras during scheduled inspections and during the engine delivery test.
Easy on-site maintenance
The enclosure is equipped with a traveling overhead crane allowing for easy offloading or loading on a truck.
Off-site maintenance with 24-hour core swap capability
For maximized availability, the gas generator can be swapped in less than 24 hours. It can be rolled out with standard maintenance tools.
Maximum fuel capability with minimum environmental impact
The fourth-generation DLE burner allows for excellent fuel flexibility. Your SGT-750 will operate on gases with high content of inert gases, hydrogen or heavy hydrocarbons as required, without any impact on maintenance or emission levels. The engine is capable to burn up to 40 vol% of hydrogen (H2).
The SGT-750 offers dual-fuel capability for all applications. It is designed to meet your individual operating criteria, including a reliable start, and changeover between fuels. The automatic changeover from gaseous to liquid fuel, and back again, can be executed at any load.
