The naturally aspirated, Siemens SGE-FR Gas Engines range from 150 to 238 kWb (201 to 319 hp). These gas engines have been designed to operate with lower quality gases, especially in oil and gas applications.

This engine series is commonly used with flare gas to provide electricity to oil and gas auxiliary equipment. It can also be used with biogas in small Waste Water Treatment Plants (WWTP) due to its efficiency in cogeneration and complete heat recovery from the engine cooled by only one circuit at 194°F (90°C).

  • Output range from 150 to 238 kWb (1500 – 1800 rpm)
  • Powered by natural gas, biogas, landfill gas, sewage gas, and flare gas
  • Supplied as a stand-alone engine, genset, or in a fully assembled containerized unit (noise insulated if required)
  • Can be used for applications without emissions restrictions

Features include —

  • Inspection doors for easy access for maintenance, operations, etc.
  • Suspended crankshaft
  • Diagonally split connecting rods
  • Bimetallic bearings for connecting rods and crankshaft
  • Aluminum alloy pistons with three rings and reduced lube oil consumption
  • Cast individual cylinder heads with four valves
  • Electric or pneumatic starter
  • All services driven by gears
