Our gaseous generators provide cost effective power by using well gas byproduct as fuel. One gaseous generator can save an oil and gas site as much as $200K per year in diesel costs.

Our gaseous generators operate on well gas, natural gas or propane and are ready to be deployed for use as prime power for a number of oil field operations. If you have off the grid power needs we have a product to fit your needs.
