When your operation demands reliable, efficient power generation with proven performance, this pre-owned Caterpillar G399 Natural Gas Generator Set delivers exceptional value without compromise. With two units available, you have the rare opportunity to secure battle-tested industrial power equipment that's ready to perform from day one.
These aren't just any used generators—both units were actively in service when removed, demonstrating their continued reliability and operational excellence. With only 15,000 hours on the clock after a comprehensive major overhaul, you're getting equipment that's been reset to deliver thousands more hours of dependable service. This is industrial power generation equipment that's proven itself in real-world applications.
Environmental compliance isn't optional—it's essential. These generator sets are California Air Quality Management District (AQMD) approved, meeting some of the most rigorous emissions standards in North America. This certification gives you peace of mind that your power generation equipment complies with strict environmental regulations, protecting your operation from compliance issues and potential penalties.
Caterpillar's reputation for building rugged, reliable power generation equipment is unmatched in the industry. The G399 engine platform is renowned for its durability, fuel efficiency, and ease of maintenance. With Caterpillar's extensive dealer network and parts availability, you're investing in equipment that's supported for the long haul.
Natural gas generators offer compelling advantages over diesel alternatives: lower fuel costs, reduced emissions, quieter operation, and simplified fuel delivery through pipeline connection. Eliminate the complexity of diesel fuel storage, delivery logistics, and associated environmental concerns while enjoying cleaner, more economical power generation.
With two identical units available, you have strategic flexibility. Purchase both for built-in redundancy that ensures continuous operation during maintenance cycles, or deploy them across multiple facilities for consistent performance standards. Either way, you're securing matched equipment with identical specifications and service histories.
The major overhaul performed before the current 15,000-hour count represents a significant investment in equipment longevity. Critical components have been inspected, replaced, or reconditioned to manufacturer specifications, effectively extending the operational life of these generators. You're getting equipment that's been professionally restored to deliver reliable performance for years to come.
Pre-owned doesn't mean compromised. These Caterpillar G399 generator sets represent smart capital allocation—delivering industrial-grade performance at a fraction of new equipment cost. When you factor in the recent major overhaul and verified operational status, you're making an investment that balances fiscal responsibility with operational reliability.
