The LM2500+ DLE gas turbine is a high-performance solution for power generation in industrial, onshore, and offshore environments where emissions control and water availability are key concerns. Delivering over 30 megawatts of power and up to 40% thermal efficiency in simple cycle operation, it offers reliable performance with low environmental impact.

At the core of its design is the advanced Dry Low Emissions (DLE) combustion system, which reduces NOx and unburned hydrocarbon emissions without the need for water or steam injection. The system achieves this by precisely managing combustion conditions and lowering flame temperature. A triple annular combustor configuration enables fuel to burn more evenly at lower temperatures across a larger area, while new electrically actuated fuel metering valves enhance control and reduce complexity compared to older electro-hydraulic systems.

The LM2500+ DLE also features a 17-stage axial compressor for increased airflow and output, along with a modular, open design that enables faster maintenance and engine replacement. Its fast start capability makes it suitable for operations requiring multiple starts and stops per day.

Whether powering industrial facilities, pipeline networks, or combined heat and power (CHP) systems, the LM2500+ DLE offers a dependable and efficient gas turbine solution that balances operational flexibility with emissions performance.

The 3-inch sleeve-style hot air purge valve is designed for aero-derivative industrial gas turbines to control the flow of hot compressor bleed air used in critical purge operations. This valve is normally closed and solenoid-pilot actuated, available in two- or three-inch sizes with elbow sleeve design. It operates on 24 or 125 VDC power and is constructed with ANSI B16.5 Class 600 raised face flanges.

Key specifications include a physical size of approximately 7.5 inches wide and 25 inches high, weighing between 84 to 91 pounds. It can handle line pressures up to 500 psig and actuation pressures between 80 and 125 psig. The valve is rated to operate in fluid temperatures ranging from 32°F to 1100°F (bleed air), and can withstand ambient temperatures between –20°F and 240°F with heat soak up to 400°F for 1 to 2 hours when de-energized.

Performance characteristics include a flow capacity of about 1.2 pounds per second of compressor bleed air with a maximum pressure drop of 0.70 psi across normal operating conditions. Internal leakage is minimal, rated at 0.00025 pounds per minute. The valve features a rapid full stroke response time of 1 second for both opening and closing cycles. It includes a position indicating switch and supports continuous duty operation.

Functionally, this valve plays a crucial role in purging residual fuels, such as diesel, from the combustor fuel lines when switching fuels, preventing deposits that can impair turbine performance or cause damage. The valve is often installed in pairs for dual redundancy to enhance safety and operational reliability. With millions of field operating hours, this design reflects high durability and precise control essential for efficient and safe turbine operation.

The 4″ butterfly bleed air valve plays a crucial role in controlling the flow of compressed air, called bleed air, from the compressor section of a gas turbine. This airflow regulation helps maintain safe and efficient turbine operation by managing pressure and protecting internal components.

This valve is built with a strong bearing shaft and specially designed bearings that handle frequent cycles, ensuring a longer service life and less maintenance. It includes a fail-safe feature that automatically opens the valve if a problem occurs, protecting the turbine from damage. With a quick response time—fully opening or closing in less than 320 milliseconds—it reacts fast to changing engine conditions. The valve’s electric components are also better insulated from heat, improving reliability even in harsh environments.

What makes the 4″ valve stand out is its ideal size and performance. It offers greater airflow than smaller valves, yet remains compact and easier to fit than larger ones, making it perfect for medium-duty applications where space and precise control are important.

Importantly, this valve is designed as a direct, plug-and-play replacement for existing models. It requires no changes to the hydraulic or electrical systems, allowing for quick upgrades without downtime. This seamless fit and reliable operation help ensure your gas turbine runs smoothly and efficiently, reducing costs and increasing uptime.

The LM2500XPRESS gas turbine is a compact and modular power system designed for fast installation and quick delivery of power when speed matters. It comes prepackaged in 10 simplified modules, which makes installation easier and faster, with only 27 electrical interconnects to manage.

This turbine is based on the proven LM2500 aeroderivative gas turbine, known for its reliability and versatility. It can be used in a wide range of power generation setups, including baseload, peaking, simple cycle, combined cycle, and cogeneration (combined heat and power) applications. The system offers dry low emissions (DLE) and can operate on gas or dual fuel.

One important feature of the LM2500XPRESS is its ability to handle daily starts and stops without increasing maintenance frequency or costs. Its free-spinning power turbine design allows it to act as a synchronous condenser without needing a clutch between the turbine and generator, which helps reduce maintenance needs and downtime.

The turbine can ramp from a cold start to full base load in about five minutes, making it ideal for situations where fast power availability is critical. Its plug-and-play design allows industrial users or grid operators to connect and begin generating electricity quickly and efficiently.

In summary, the LM2500XPRESS combines a reliable aeroderivative gas turbine with a smart, modular package designed for rapid deployment and flexible power generation.

The LM2500+G4 SAC 50Hz Combined Cycle 2x1 is a high-performance gas turbine system designed for large-scale, high-efficiency power generation, particularly suited to the needs of oil and gas operations. This configuration links two LM2500+G4 gas turbines with a single steam turbine in a combined cycle layout—capturing waste heat from the gas turbines to produce steam and generate additional power. This approach significantly improves overall thermal efficiency while maintaining operational flexibility.

The Single Annular Combustor (SAC) with optional water injection helps the system meet emissions rules while keeping combustion stable and efficient. The LM2500+G4 improves on the previous +G4 model by increasing airflow, using better materials, and adding improved cooling. This allows it to produce about 10% more power without reducing the lifespan of critical hot parts. It can be equipped with either a two-stage or six-stage power turbine to fit different needs. Even with the higher power output, the +G4 keeps its modular, two-spool design, which makes maintenance easier and ensures reliable performance in many environments.

In the 2x1 configuration, the system delivers approximately 41% more power than a single gas turbine unit. The use of combined cycle technology ensures better fuel utilization, helping to reduce overall emissions and lower lifecycle operating costs.

The LM2500+G4 SAC 50Hz Combined Cycle 2x1 offers higher power, improved efficiency, and a flexible design, making it well-suited for large-scale oil and gas operations that demand reliable and efficient power generation. Its “50Hz” designation means the turbine is specifically optimized to supply electricity to grids operating at 50 cycles per second, ensuring seamless integration with regional power systems.
