Engineered for industry-leading power output and fuel savings

The SGT-A65 (Industrial Trent 60) has established a new benchmark for power output as well as fuel and cost savings. With this highly flexible gas turbine you will benefit from high power and efficiency ratings with only a minimal drop-off at part-load and reduced-speed conditions. It is available with Wet Low Emission (WLE) and Dry Low Emission (DLE) combustion systems.

SGT-A65 (Industrial Trent 60) gas turbine highlights

Due to its independent 3-shaft design, this gas turbine is highly flexible, offering high power output and fuel effiency with minimal drop-off at part-load and reduced-speed conditions.

For a simple cycle SGT-A65 package, the start-up sequence time is designed to be less than 7 minutes – from pressing the start button to reaching full base load. This includes an allowance for a simple cycle exhaust system purge. A 5 min cold start option is available upon request under consideration of project  specifications. 

The SGT-A65 boasts the most extensive mechanical drive experience in its class. It is ideally suited to meet the higher power, variable speed demands required, for instance, for natural gas liquefaction, gas transportation, or gas induction for oil recovery.

One of the most efficient gas turbines on the market, the SGT-A65 provides up to 71 MW in simple cycle service at 43.8% efficiency. With its fast cold start capability and high cyclic life, this engine can rapidly add power to the grid to compensate for fluctuating and variable renewable and other energy sources – making it your ideal solution for peaking markets.

The SGT-A65 consists of 8 engine modules for easy maintenance. Each module is pre-balanced to make it completely interchangeable.

The inlet spray intercooling (ISI) system improves the gas turbine's performance at ambient temperatures above 7 °C (45 °F) better than comparable inlet cooling technologies with similiar peformance enhancement – while minimizing additional water consumption and auxiliary load.

Ingenious design to the core

The SGT-A65 is designed for flexibility so that you can use the same engine for power generation as well as mechanical drive service, without any changes. The mechanical arrangement uses three coaxial independently rotating shafts contained within a carcass of axially joined circular cases.

Dry Low Emissions (DLE) combustion system for clean combustion

A Wet Low Emissions (WLE) combustion system is used to reduce emissions and boost performance with the injection of water.

SGT-A65 packages

The package is designed for quick installation and easy maintenance in the field. The package contains all components and subsystems that we have carefully selected and optimized to support the SGT-A65 gas turbine:
Core engine, enclosure, base frame, air intake, exhaust collector, engine control system, fuel metering skid, lubricating systems, starter system, vibration monitoring system, firefighting system, package ventilation system, instrumentation, gearbox (if needed).

Power generation package

The AC generator is self-contained and has an air-cooled brushless exciter design using shaft-mounted axial blowers for circulating cooled air. It also encompasses line and neutral cubicles and has an off-skid mineral lube oil system.

Mechanical drive package

A 60 Hz machine running at 3,400 rpm, which allows for 70–105% speed operation per API requirements, is used for mechanical drive applications. For this purpose, the engine is required to start a full train without the use of helper motors, whether the train is unloaded or fully pressurized. We have shown through both experience in mechanical drive applications as well as tested that the SGT-A65 can manage these torque loads with margin.

The SGT-A65 fires up

The SGT-A65 exhaust hood can be rotated in 3 directions, which allows customized configuration depending upon the available space. The power density of high aeroderivative power in a small and lightweight package is well suited for land use with more green open space.

Comprehensive services to support you

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.

 Whether for scheduled service or short-term support, our specialists are there for you, on-site all over the world.

Maintenance of the SGT-A65 engine can be accomplished quickly and easily due to the aero engine design.

Quick exchange of components

The modular design of the SGT-A65 engine enables a rapid exchange of components, while detailed work is carried out at a major overhaul facility. Your benefit? Greatly reduced downtime for engine maintenance.

Quick engine replacement

The package facilitates engine replacement in under 24 hours of working time.

Fuel flexibility matters

DLE – 34 to 48 WI / WLE – 34 to 52 WI

Liquid fuel operation

Due to the aeroderivative heritage, the SGT-A65 can operate on liquid fuels without an EOH (equivalent operating hour) penalty. In fact, the SGT-A65 has shown complete liquid operation without performance or component life degradation.

Equipped with WLE burners, the engine is capable to burn up to 100 vol% of hydrogen (H2).
With DLE burners, the hydrogen capability is up to 15 vol%.

Designed to meet stringent environmental requirements

The SGT-A65 Dry Low Emissions (DLE) engine uses eight radial staged combustors to successfully run in part-load operation while still complying with NOₓ and CO regulations.

NOₓ emissions:  ≤ 25 ppmvd on fuel gas (with WLE and DLE, at 15% O₂)
