MAN Generators

Much of the landfill gas industry effort has focused producing electricity for export to the grid with the large Caterpillar 3500 and 3600 series generator packages. However, as more and more landfills are looking for ways to cut cost to stay competitive, one overlooked area is using smaller LFG IC engines to provide on-site power needs. The industry buzz words are “co” or “tri” generation, distributed generation and net-metering. Our focus is “Economic Energy” and the MAN engine meets that need.

MAN engines provide:

  • Exhaust emissions available to 0.6 grams/brake horsepower/hour on turbocharged units.
  • Both jacket water and exhaust heat recovery systems
  • Proven zero pressure fuel gas regulator
  • Can reach full load off a flare blower
  • Generator or compressor direct drive application
  • Proven history on landfill and digester gas
  • LFG Tech can provide a turn-key application with guaranteed pricing before installation. You won’t have to figure it out for yourself
  • LFG Tech will handle warranties
  • O&M and replacement parts stocked in US
  • Lowest IC capital and operating cost
  • E-08 units have one head per two cylinders. E-28 units have one head per cylinder for ease of maintenance.
  • Beats Micro Turbine on capital and operating cost
  • BLACK-START capable
