Powered by decades of engineering excellence, Guascor Energy remains a global leader in gas and diesel engines for power generation, cogeneration (CHP), waste-to-energy, marine, and industrial applications.  Whether you run legacy Dresser Rand / Siemens-era engines or modern Guascor fleets, having access to OEM-grade spare parts is crucial for reliability, performance and regulatory compliance.

At GBS Power, we provide high-quality spare parts for all major Guascor Energy / Siemens Energy / Guascor Power / Dresser Rand engine models — ensuring plant uptime, operational efficiency, and long-term value.

🎯 Why Genuine Guascor Energy & Siemens Energy Engine Spare Parts Matter

• Guascor engines are engineered for fuel flexibility — natural gas, biogas, LPG, flare-gas, even hydrogen blends — requiring precision components for optimal combustion and longevity.  
• Using OEM-standard parts helps maintain low life-cycle cost, high efficiency and low emissions — core design principles of Guascor Energy engines.  
• Upgrades, overhauls or retrofits (especially for older Dresser Rand / Siemens-era engines) benefit significantly from components manufactured to original specifications.

🛠️ Full Model Coverage — All Guascor / Siemens / Dresser Rand Engines

We supply spare parts for the complete family of Guascor (and legacy) engines, including:

S-Series Gas Engines

• Models: G-18SL, G-24SL, G-36SL, G-48SL, G-56SL — covering 209 kW to ~1,150 kW mechanical power output depending on configuration.  
• Also variants: SM, SR — for different fuel types and application needs.  

H-Series Gas Engines (HM / HM engines)

• Engines: G-24HM, G-42HM, G-56HM — robust gas engines with high fuel flexibility, designed for natural gas, landfill/sewage gas, LPG/propane, and mixed fuels.  
• These are suited for power generation, cogeneration, waste-to-energy and industrial gas-power tasks, with options for single- or double-stage charge-air cooling, turbocharging, and advanced engine control systems.  

E-Series / EM Gas Engines

• High-performance engines: 86EM, 100EM — delivering up to 2,065 kWb mechanical output @ 50 Hz or 60 Hz, with high efficiency, compact footprint and lean-burn design.  
• Ideal for industrial power generation, CHP, distributed generation where space, emissions and efficiency matter.  

Legacy / Naturally-Aspirated Engines (FG / FG-Series / Dresser Rand Guascor)

• Series like FG — historically used for flare-gas, biogas and lower-quality gas applications; output ranges ~150–238 kWb.  
• Also possibly older diesel engine series under legacy “Guascor Power / Dresser Rand” naming — useful for operators with older gensets.

Marine & Auxiliary Gas/Diesel Engines

• Guascor Energy also offers gas and diesel engines for marine propulsion, auxiliary power on vessels, tugs, workboats, etc.  
• Their gas-marine engine series includes models like G-18SL, G-24SL, G-56SL with outputs from ~256 kWe to ~888 kWe for auxiliary power sets.  

🔧 Spare Parts & Services We Provide (for All Models)

For all above engines — whether modern Guascor Energy, Siemens-era, or legacy Dresser Rand — we offer:

• Cylinder head kits, valves, liners, piston kits
• Gasket & sealing sets (top-end, bottom-end)
• Turbocharger & air-system components
• Fuel/ignition system parts (injectors, ignition, spark-plugs etc.)
• Cooling & lubrication parts (water-pump, oil-pump, hoses, thermostats)
• Marine-specific spares (for auxiliary and propulsion engines)
• Full overhaul kits, maintenance spares, and upgrade support

🔄 Fuel Flexibility, Emission Compliance & Future-Ready (H₂ & Blended Gas capable)

One of the strongest advantages of modern Guascor Energy (and by extension, Siemens / legacy fleet) engines is fuel flexibility: natural gas, biogas, landfill/sewage gas, LPG/propane, flare-gas, syngas — and increasingly hydrogen blends (H₂-ready). 

This makes them ideal for evolving regulatory standards and sustainability-driven operations — especially useful in industrial, waste-to-energy, or biomass-based projects.

🏭 Who Benefits: Applications & Industries

• Industrial power generation plants (gas / biogas / hybrid fuel)
• Waste-to-energy & sewage/landfill gas plants (CHP / gensets)
• Distributed generation and remote/off-grid installations
• Marine vessels: auxiliary and propulsion engines (commercial ships, bunkering vessels, tugs, workboats)
• Industrial CHP, cogeneration facilities, combined heat + power systems

All these benefit from robust performance, fuel flexibility, emission compliance, and long-term reliability when using OEM-grade spare parts.
