Fuel Gas Boosters

LFG Tech provides custom built fuel gas boosters for Caterpillar, Jenbacher and Waukesha landfill gas engines. Both Jenbacher and Waukesha typically require dehydration to meet the OEM humidity requirements and max gas tempuratures. All LFG engine fuel gas boosters need moisture control as part of the operations; however, Caterpillar operating requirements can be met with ambient temperature control and filtering. This substantially reduces operating cost.

The following pictures and simple diagrams provide the typical operational logic for a Caterpillar 3500 series engine and a Waukesha or Jenbacher engine:
