Caterpillar is an American manufacturer headquartered in Deerfield, Illinois, and the world's largest producer of industrial diesel engines and generator sets. CAT gensets dominate standby power for data centers, hospitals, and manufacturing, alongside prime power for mining, oil and gas, and remote industrial operations. On the used market, CAT equipment benefits from exceptional parts availability — engines remain serviceable through the global dealer network for decades.

Used Caterpillar generator sets on Exapro span small workshop standby units (20-100 kW), mid-range commercial and industrial gensets (100-500 kW), large industrial and data center backup units (500 kW-2 MW), and multi-megawatt CAT gensets (3.5 MW and above) for major facilities.

Caterpillar Inc. is the world's largest manufacturer of industrial diesel engines and generator sets, headquartered in Deerfield, Illinois, with production facilities and dealer networks spanning every major market.

On the used market, Caterpillar generator sets are accessible workhorses with exceptional parts availability — even 20-30 year old CAT engines remain serviceable through the global dealer network. Exapro listings cover small standby gensets (20-100 kW for commercial standby, telecom, and small industrial applications), mid-range units (100-500 kW for offices, hospitals, manufacturing), large gensets (500 kW-2 MW for major facilities and data center backup), and multi-megawatt machines for major installations. Compare current CAT listings to find the right power class for your application.

Key inspection points before buying include engine hours (gensets with under 5,000 hours are low-time, 10,000-20,000 hour units are still serviceable but need closer inspection), recent service records, oil analysis history, alternator condition, control panel (CAT EMCP or similar) functionality, and any emissions-compliant certification documentation.

Buying a used Caterpillar generator set: what to check

Before purchasing any used generator set, thorough inspection is essential. For Caterpillar gensets specifically, engine hours and maintenance history are the primary value drivers. Low-hour CAT engines (under 5,000 hours) typically warrant premium pricing, while higher-hour units (10,000+ hours) need closer inspection of major components and recent service investment.

Verify the alternator condition affects electrical output quality — test voltage regulation and waveform under load if possible. CAT EMCP control panel functionality should be tested including any remote monitoring features. For emission-compliant gensets, certification documentation must be available. Request oil analysis history and recent service records.

Transport for CAT gensets requires careful planning — small units ship in standard freight, while units above 5,000 kg need dedicated heavy-haul logistics adding €3,000-€15,000 to delivery cost depending on destination. Confirm machine dimensions, weight, and electrical specifications. On Exapro, each CAT listing provides specifications, photos, and seller contact. Compare multiple CAT listings to find the right combination of power rating, hours, condition, and value for your power generation needs.
