SGT-A05 aeroderivative gas turbine

The SGT-A05 gas turbine is based on a proven aeroderivative design. It is flexible, compact and lightweight, making it ideal for decentralised power generation. It offers high efficiency and can start up in just 60 seconds.

SGT-A05 gas turbine variants generate electrical power outputs of between 4 and 6 MW for applications such as base load, cogeneration, combined heat and power, mobile power and emergency power. Since its introduction in 1963, over 1,720 SGT-A05 gas turbines have been sold to more than 500 industrial customers in 55 countries, accumulating an impressive 133 million operating hours.

Ingenious design to the core

The SGT-A05 (Industrial 501-K) gas turbine engine is an aero-derived engine based on the T-56 turboprop, which is recognized for its reliability and durability in the Lockheed Martin C-130 Hercules transport, E2C Hawkeye, P-3 Orion and other widely used aircraft. The aeroderivative design of the SGT-A05 series engine provides a lightweight, modular product that helps lower operating costs through improved fuel consumption, extended hot section life and ease of maintenance.
Designed for power generation, and oil and gas applications, features of the SGT-A05 gas turbine include:

Lightweight modular construction
Ease of field repair
Virtually limitless starts and stops
Wide range of fuels in all ambient conditions
High electrical and cycle efficiency

Packaged for success – Packages for industrial power generation, O&G power generation and mobile power unit solution

The SGT-A05 (Industrial 501-K) packages are designed with noise suppression, access doorways, as well as safety interlocks supporting the health and safety of the operation and maintenance staff. The packages are compact and easily transported, installed and maintained.

For power generation applications like cogeneration and emergency power applications, the package features include:

Lubricating oil system
On-skid fuel system
Several types of start systems are available depending on your requirements

Complete customer care for the SGT-A05 gas turbine

The 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

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.
