Mainspring systems can operate directly on field gas, biogas, or other non-standard fuels with minimal conditioning. This converts waste or flare gas into productive power while maintaining low emissions and high efficiency.
Yes. The linear generator’s modular, standalone design supports microgrids or fully islanded operation for oil and gas, wastewater, agriculture, landfill, or other industrial sites, delivering reliable power without dependence on grid infrastructure.
With no combustion, lubricating oil, or complex moving parts, Mainspring systems require minimal maintenance. Routine service is predictable and modular, allowing most of the plant to remain powered during maintenance.
Yes. The low-temperature process produces near-zero NOx and no detectable particulate matter, allowing deployment in the strictest air districts without after-treatment.
Factory-built, pre-tested units ship ready to install and integrate easily with existing electrical and fuel infrastructure. This minimizes onsite construction and shortens time-to-power for critical industrial applications.
