FAQ

Gas Generator FAQ

Have questions about Gas Generators or our services? Learn more about our products and why customers choose IPP.

What’s the difference between standby and continuous-duty gas generators?

Standby generators provide backup power during outages, while continuous-duty models are designed to run for extended periods, supporting base-load energy needs.

Are CHP (combined heat and power) systems available used?

Yes – many used gas generators at IPP include or support integration with heat recovery systems for combined thermal and electrical output.

Can I use biogas or alternative fuels with these generators?

Absolutely – several generator models are dual-fuel capable or optimized for biogas, landfill gas or syngas applications.

What are the benefits of buying used or secondhand process equipment from IPP?

You get faster turnaround, significant savings, and expert support from a team with more than 47 years of industrial project experience.
