The LM2500 DLE Gas Turbine is an advanced power generation unit designed to deliver high efficiency while significantly reducing emissions. Utilizing cutting-edge Dry Low Emissions (DLE) technology, it precisely controls fuel and air mixing to minimize nitrogen oxide (NOx) emissions.

The LM2500 DLE utilizes a single-rotor gas generator with a 16-stage compressor and a two-stage high-pressure turbine, coupled with cutting-edge DLE combustion technology to reduce nitrogen oxide emissions. It supports dual-fuel operation on a wide variety of fuels, including natural gas, diesel, aviation fuel, LPG, and even hydrogen blends with concentrations ranging from 5% to 95%. The turbine’s open configuration allows for faster maintenance and quicker engine replacement, minimizing downtime.

Its key benefit is utilizing advanced aeroderivative gas turbine technology with dual-fuel Dry Low Emissions (DLE) capability, achieving ultra-low emissions of just 15 ppm NOx on gas fuel, combined with broad fuel flexibility—making it ideal for meeting strict environmental regulations while providing fast, reliable power for dynamic grid demands.

The 2.5″ Butterfly Bleed Air Valve is a critical component in the LM2500 gas turbine, responsible for regulating the flow of bleed air—compressed air extracted from the turbine’s compressor stage. This valve helps control internal pressures and temperatures, which is essential to maintain safe and efficient turbine operation.

The valve has an effective flow area of 2.5 square inches, allowing it to manage airflow precisely in smaller turbine setups or space-restricted environments. Its butterfly-shaped disc is permanently attached to the shaft, which ensures consistent movement and reliable control of air flow with minimal play or slippage.

One important feature is its fast response time—less than 320 milliseconds to complete a full open or close stroke. This quick action enables the turbine control system to rapidly adjust pressure levels, preventing overheating and reducing mechanical stress on turbine components.

The valve’s bearing shaft is robustly designed to handle frequent small movements, known as dither cycles, without premature wear. The bearings themselves are specifically engineered to support these high-cycle conditions, improving the valve’s durability and lifespan.

By efficiently managing bleed air, this valve helps protect the turbine from excessive pressure build-up and thermal stress, which can otherwise lead to damage or reduced efficiency. Its design also allows installation without requiring changes to the turbine’s hydraulic or electrical systems, making it suitable for retrofits or upgrades on existing LM2500 turbines.

In summary, the 2.5″ Butterfly Bleed Air Valve plays a vital role in controlling compressor bleed air in LM2500 turbines, balancing safety, performance, and durability within compact or smaller turbine applications.

The LM2500XPRESS+G5 DLE UPT is a modular aeroderivative gas turbine system built for fast, flexible, and efficient power generation in both onshore and offshore environments. It is particularly well-suited for applications across LNG facilities, gas pipelines, gas processing plants, and general power generation, including electricity production at both 50 and 60 Hz, without the need for a speed reducer.

The "+G5" designation refers to its fifth-generation power turbine, offering the highest output and efficiency in the 20–40 MW class. It supports both high-speed and low-speed power turbine configurations, allowing integration into a variety of grid or mechanical drive systems.

At its core, the G5 includes a high-pressure compressor derived from the LM2500+G4, now redesigned for longer service life. In a simple cycle, it achieves up to 41% efficiency, which is notable for a turbine of this size class. The system can start from cold and reach load in about five minutes, making it ideal for rapid-response applications.

The unit is built for speed and simplicity. It’s shipped in preassembled modules, with a compact footprint that helps reduce installation time.

The Dry Low Emissions (DLE) system supports environmental compliance without requiring water or steam injection, simplifying operations and reducing resource demands.

Altogether, the LM2500XPRESS+G5 DLE UPT provides a practical solution for projects that need reliable, fast, and efficient power without a complex setup.

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.

The LM2500 is a multi-shaft gas turbine featuring a free-spinning power turbine, making it well-suited for dynamic and high-demand environments such as those found in oil and gas operations. In this design, the high-pressure turbine and compressor are mechanically independent from the low-pressure power turbine. This separation allows the power turbine, which drives the electric generator or mechanical load, to respond rapidly to changes in load demand. Its ability to accelerate quickly makes it ideal for applications where maintaining grid stability or mechanical output is critical. In scenarios where frequency fluctuations occur, the free power turbine can quickly compensate, helping to stabilize the grid and ensure smoother operation of all connected systems.

In its standard configuration, the LM2500 is equipped with a six-stage, low-speed power turbine. This turbine operates at a nominal speed of 3600 rpm and is designed to deliver reliable shaft power in steady-state conditions, making it particularly effective for electric power generation or mechanical drive in pipeline and process operations.

For applications requiring greater flexibility or higher continuous output speeds, the LM2500+G4 variant offers enhanced capabilities. It is available with either the standard six-stage, low-speed power turbine or an alternative two-stage high-speed power turbine. The high-speed variant is engineered for mechanical drive and other demanding industrial uses, with a design speed of 6100 rpm and an operating range from 3050 to 6400 rpm. This configuration supports continuous high-speed shaft output where needed and is particularly beneficial for compressors and other rotating equipment in oil and gas facilities.

Both the six-stage and two-stage power turbines can be operated over a cubic load curve, providing the adaptability required for variable load profiles commonly encountered in oil and gas operations. This flexibility, combined with the LM2500’s rapid response characteristics and modular design, makes it a dependable choice for critical infrastructure in upstream, midstream, and downstream sectors.

The LM2500 Wrench – Horizontal/Vertical HPT Coupling Nut is a specialized maintenance tool designed for the LM2500 gas turbine engine. This wrench is used to install and remove the High Pressure Turbine (HPT) coupling nut, a critical component that secures the HPT rotor to the turbine shaft.

Removing and installing the coupling nut is necessary during major maintenance activities like rotor inspections, repairs, or when replacing key turbine components. Proper removal allows technicians to safely separate the rotor from the shaft, while correct installation ensures the rotor is securely fastened for reliable engine operation.

What makes this wrench stand out is its ability to work with both horizontal and vertical engine positions. This means technicians can use it easily no matter how the engine is set up, making maintenance simpler and more flexible.

Built to precise standards and made from tough materials, the wrench ensures the right amount of force is applied when tightening or loosening the coupling nut. This careful control helps protect the engine’s important parts from damage.

By using this wrench, maintenance teams can complete their work faster and with confidence, reducing downtime and keeping the turbine reliable. It’s an essential tool that supports the smooth operation of the LM2500 engine.
