"Our combined experience provides a resume
of over fifty (50) landfill gas projects producing over 150 Megawatts of
power and consuming in the billions of cubic feet of landfill gas
daily."

CAT LFG Gas Engines
Caterpillar 3500 series engines set the standard for landfill
gas. Other prime movers have tried, but when you take a look at the total
cost of ownership, other prime movers do not come close. The total cost of
ownership includes fuel gas boosters, siloxane tolerance, fuel pressure, parts
availability and field support.
CAT engines provide:
- Exhaust emissions available to 0.5
grams/brake horsepower/hour on G3520's
- 1200 RPM operations
- Both jacket water and exhaust heat recovery systems
- Low fuel pressure @ 2 PSIG
- 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
- O&M and replacement parts usually available within
24 hours
- BLACK-START capable.
