Made from strong, durable materials, the fixture set is built to support the heavy upper compressor case while keeping everything properly aligned. Its reliable locking and hinge system holds the case securely in place, helping protect the gas turbine.

Compatible with both OEM and MRO procedures, this fixture supports efficient, repeatable maintenance practices and helps reduce overall engine downtime. Whether used in the field or in a dedicated maintenance facility, the LM2500 Hinge Fixture is a critical tool for safe and effective servicing of the LM2500 engine’s compressor section.

The LM2500+ DLE 50Hz Combined Cycle 2x1 system combines two LM2500+ dry low emissions gas turbines, each coupled with a Heat Recovery Steam Generator (HRSG), to power a single steam turbine. This high-efficiency configuration is engineered to meet larger capacity needs, delivering reliable, low-emission power with rapid startup capability.

At the core of this system is the LM2500+, an uprated version of the LM2500, featuring a 17-stage compressor. The addition of a forward-stage blisk increases airflow by approximately 20% at full power. This enhancement boosts the compressor pressure ratio from 18:1 to 23.1:1, contributing to higher overall efficiency and output.

Downstream of the compressor, the engine incorporates a fully annular combustor with externally mounted fuel nozzles, a two-stage air-cooled high-pressure turbine driving the compressor and gearbox, and a six-stage low-pressure power turbine aerodynamically coupled to extract energy from the high-energy exhaust flow. To accommodate the increased output, key design changes were made to the power turbine, including aerodynamic blade optimizations and rotor strengthening.

The Dry Low Emissions (DLE) system plays a crucial role in minimizing environmental impact. Its triple annular combustor lowers flame temperature, reducing NOx and CO emissions without water or steam injection—improving both thermal efficiency and maintainability.

Together, this 2x1 configuration offers a scalable solution for utility and industrial operators seeking clean, efficient, and dependable power generation at higher capacities.

The LM2500+ gas turbine delivers increased power and improved efficiency by building on the proven LM2500 platform. Designed to meet the demanding needs of industrial and offshore operations, it offers a compact, reliable solution for power generation and mechanical drive applications.

The LM2500+ enhances the original LM2500 design by adding a 17-stage high-pressure axial compressor. This additional compressor stage increases airflow and raises the engine’s pressure ratio, resulting in roughly 20% more power output. The turbine uses a ring combustion chamber with advanced dry low emissions (DLE) technology, producing very low levels of NOx and CO emissions to meet strict environmental standards.

A key feature of the LM2500+ is its low-speed turbine section, which is specifically designed for offshore platforms and other space-restricted environments. This turbine’s compact size and modular design allow for easy maintenance, with split compressor casing and in-place blade replacement that reduce downtime and operational complexity. The turbine is factory-tested and pre-wired for straightforward installation, supporting both 50 Hz and 60 Hz power generation without the need for additional equipment like reducers.

Operators benefit from the LM2500+’s enhanced power and fuel efficiency, which help reduce operational costs and improve performance in applications such as combined heat and power systems, industrial power generation, underground gas storage, and gas pipelines. Its modular, space-saving design fits well in offshore installations where size and weight are critical factors.

the LM2500+ ensures continuous performance and maximizes uptime, making it a trusted solution for critical power needs across various industrial and offshore applications.

The LM2500 Gas Generator is the core component of the LM2500 gas turbine, responsible for producing the high-energy gas flow needed to drive the power turbine. It features a 16-stage axial compressor that efficiently compresses incoming air, a single annular combustor where fuel and air mix for optimal combustion, and a two-stage high-pressure turbine that extracts energy to power the compressor.

Designed for durability and high performance, the LM2500 Gas Generator supports a wide range of fuel types, including natural gas and liquid fuels, enabling flexible operation in various industrial and marine settings. Its modular construction allows for easier maintenance and faster engine removal or replacement, minimizing downtime.

With advanced aerodynamics and robust engineering, the LM2500 Gas Generator delivers reliable, efficient gas flow, helping ensure consistent power output and lower emissions across demanding operating conditions.

The LM2500 SAC Gas Turbine features a Single Annular Combustor (SAC) system—a type of combustion chamber where fuel and air are mixed and burned in a single, annular-shaped chamber. This design allows for efficient combustion with lower emissions and better fuel-air mixing. The turbine also supports dual-fuel capabilities, operating on both gas and diesel, offering greater flexibility in environments where fuel availability may vary.

Its open configuration is designed for accessibility, making maintenance tasks faster and more straightforward. This also allows for quicker engine removal or replacement, helping reduce downtime during service operations.

The LM2500 SAC is widely used across multiple industries, including electrical power generation, mechanical drive systems, and marine propulsion, due to its reliability, fuel flexibility, and proven performance in demanding conditions.
