Buying Used Natural Gas Generators from Gas Engine Exchange

Whether you are powering an industrial site, a landfill project, or a standby power application, buying used natural gas generators is one of the most cost-effective ways to secure reliable power generation equipment without the lead times and price tag of new units. At Gas Engine Exchange, our stock of used natural gas generators for sale spans trusted brands including Caterpillar, Jenbacher, and MAN, covering a wide range of power outputs from smaller 250kW units up to multi-megawatt generating sets suited to larger commercial and industrial demands.

When selecting a used generator, it is worth considering the fuel type your site requires (natural gas, biogas, or landfill gas), the available running hours remaining on the engine, and how the unit has been stored and maintained since it was decommissioned. That is why every engine we sell goes through a professional appraisal, including mechanical inspection, boroscope examination of the cylinders, and a full review of service history, so you can buy with confidence.

If you are not sure which generator fits your project, get in touch with our team - we are happy to talk through your power requirements and help you find the right match from our current inventory.
