LM2500 Fixture, Hinge – Upper Compressor Case is a specialized tool set designed to safely raise and hinge open the upper compressor case of the LM2500 gas turbine engine. This fixture is essential during major maintenance, inspection, or overhaul activities where access to the engine’s internal compressor components is required.

The fixture allows maintenance teams to lift and securely hold the heavy upper compressor case in a hinged, open position. This provides stable and safe access to the compressor rotor and other internal parts, ensuring technicians can carry out detailed inspections or repairs without risking damage to sensitive components.

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 Single Annular Combustor (SAC) version of the LM2500+G4 is designed for oil and gas applications that prioritize consistent performance, fuel flexibility, and emissions control—such as LNG facilities, gas processing plants, and pipeline compression, both onshore and offshore.

What makes the SAC version different is its simpler combustor design compared to dual annular or premix types. The SAC uses a through-flow, venturi swirler to ensure an even temperature profile at the turbine inlet, helping extend hot section life. It features individually replaceable fuel nozzles, a durable machined-ring liner, and a thermal barrier coating for better resistance to high temperatures and corrosion. This design supports both dry operation (with higher emissions) and water or steam injection to reduce NOx when needed—making it adaptable to site-specific emission regulations.

The LM2500+G4 SAC builds on the proven LM2500+ design, with approximately 10% more power. This gain comes from increased airflow, improved internal cooling, and material upgrades—while keeping the same number of compressor and turbine stages. The 17-stage high-pressure axial compressor and the basic engine layout remain unchanged, making it easy to maintain and service.

The engine can run on a wide range of liquid and gas fuels, allowing flexibility in remote or supply-constrained locations. It achieves up to 40% thermal efficiency in simple cycle mode. Water-injected operation enables NOx emissions as low as 25 ppm (gas) and 42 ppm (liquid).

In short, the LM2500+G4 SAC is well-suited for high-power mechanical drive and power generation in harsh or remote oil and gas environments, offering a balance of power output, fuel versatility, and emissions control.

The LM2500+ DLE gas turbine is designed to provide reliable, efficient while meeting strict environmental rules. Ideal for power plants where emissions limits and water availability are critical concerns, the LM2500+ DLE provides clean, flexible, and high-performance power generation.

Using advanced Dry Low Emissions (DLE) technology, it reduces nitrogen oxide (NOx) and carbon monoxide (CO) emissions without requiring water or steam injection. This makes it especially valuable for facilities aiming to minimize environmental impact and avoid the operational complexity and maintenance costs associated with water-based emissions control systems.

The turbine’s ability to maintain NOx emissions below 25 ppm on natural gas—and as low as 15 ppm under certain conditions—ensures compliance with tough air quality standards.

With a power output exceeding 31 megawatts and thermal efficiency above 40%, the LM2500+ DLE suits a broad range of applications, from utility-scale electricity generation to industrial cogeneration and offshore power. Its fast start capability and robust cycling performance enable it to respond quickly to fluctuating grid demands, making it an excellent partner for integrating renewable energy sources.

Fuel flexibility extends the LM2500+ DLE’s usability across different operational contexts. It runs smoothly on natural gas, diesel, aviation fuels, and even hydrogen blends—offering operators confidence and versatility regardless of fuel availability or market conditions.

Maintenance is simplified thanks to the turbine’s modular design, allowing rapid access and part replacement. This reduces downtime and keeps plants running efficiently, enhancing overall productivity.

Combining power, efficiency, emissions control, and fuel flexibility, the LM2500+ DLE supports effective and compliant power generation in a variety of operational settings.

The E3/E17 off-engine electrical cables are designed for resilience in the toughest of applications. To protect the critical wiring components from exposure to harsh environmental conditions, these cables incorporate rugged materials and advanced protective features.

Used with LM2500 gas turbines, these cables are located outside the engine and serve as essential links between the turbine’s internal control systems and external instrumentation, control panels, and auxiliary equipment.

Built to withstand vibration, moisture, extreme temperatures, and chemical exposure, E3/E17 cable harnesses include stainless steel connectors, rubber or fluoropolymer over-molding, and electromagnetic interference (EMI) shielding to maintain signal integrity and durability.

The E3/E17 classifications indicate different cable configurations and connector types tailored for specific LM turbine system requirements. Both ensure reliable transmission of electrical power and control signals critical to turbine operation, safety, and performance monitoring.

Manufactured with custom materials and protective coatings, these cables comply with hazardous location standards such as ATEX and UL/CSA certifications. Their robust design provides long service life with minimal maintenance, supporting high fleet availability and operational reliability.

In oil and gas applications, where equipment is exposed to extreme environments and strict safety regulations, the E3/E17 off-engine cables offer dependable, durable connectivity. Their rugged construction and certification for hazardous locations make them ideal for maintaining safe, continuous turbine operation in demanding field conditions.

The Packing O-Ring is a sealing made from durable fluorocarbon rubber, designed for use in high-temperature and chemically harsh environments. Commonly used in gas turbines such as the LM2500 series, it provides a tight seal between components to prevent the leakage of fluids or gases.

This O-ring has an inside diameter of 27/64 inches, a thickness of 5/64 inches, and a hardness of 75 Shore A. It is built to handle operating temperatures from -20°F to 400°F, making it suitable for sealing joints in systems exposed to fuels, oils, and high pressures.

Its compact size and resistance to compression set and fluid exposure make it ideal for use in shafts, housings, and valve assemblies where reliable sealing is critical to turbine performance and safety.

The LM2500+ DLE in a 1x1 combined cycle configuration—one gas turbine, one heat recovery steam generator (HRSG), and one steam turbine—delivers significantly higher efficiency, exceeding 50% in combined cycle mode.

Designed for high thermal efficiency, fast start capability, and reduced emissions, the LM2500 family is widely used across onshore and offshore environments, including industrial plants, pipeline stations, CHP systems, and utility-scale power production.

The DLE combustion system enables the LM2500+ to maintain low NOx and CO emissions without the need for water or steam injection—simplifying operations and reducing water-related maintenance.

Key features include:

• Triple annular combustor design for even temperature distribution and lower emissions across the power range
• Electrically actuated DLE fuel valves replacing traditional electro-hydraulic SAC valves for better control
• 75 pre-mixers in 30 external modules, creating a consistent lean fuel/air mixture
• NOx emissions ≤15–25 ppm and CO emissions ≤25 ppm (on natural gas, full load)

With fast ramp-up—achieving base load from cold start in under five minutes—the LM2500 is an ideal choice for fast-start and cycling applications. This performance makes it well suited to dynamic grid environments and industrial use cases requiring quick responsiveness.
