Keep Your Business Running When the Grid Goes Down
When power outages strike, your business can't afford to stop. The Cummins C50D6 Diesel Generator delivers reliable backup power to protect your operations, equipment, and profits. This commercial-grade generator is engineered for businesses that demand dependable standby power.
What Makes This Generator Stand Out
Proven Cummins Engine Technology At the heart of this generator is a rugged, industrial-grade Cummins QSB3.3 diesel engine built to last. The liquid-cooled design runs at a quiet 1800 RPM, delivering consistent power while keeping noise levels low. With superior emissions control and rapid response to changing power demands, this engine is designed for the long haul.
The Cummins QSB3.3 is a highly reliable, compact 4-cylinder industrial diesel engine that combines the mechanical durability of the foundational B3.3 platform with modern electronic controls.
Key Performance Strengths
- Durable Build: Features a cast-iron parent-bore block with deep skirts, structural stiffening ribs, and a two-valve crossflow cylinder head designed to resist thermal fatigue.
- High Pressure Common Rail (HPCR): Upgraded with Cummins Quantum System electronics and common-rail fuel delivery for better atomization, faster cold starts, and rapid self-diagnostics.
- Emissions Simplicity: Meets Tier 3/Stage IIIA off-road standards using in-cylinder combustion technology without needing complex external exhaust gas recirculation (EGR) systems.
- Compact Footprint: Delivers 80 to 110 horsepower (up to roughly 306 lb-ft of torque) while weighing about 30% less than standard 4.0- to 4.5-liter displacement alternatives.
Professional-Grade Power Generation The alternator uses advanced 2/3 pitch windings to handle demanding motor starts and maintain clean power even with sensitive electronic equipment. You'll get reliable electricity that won't damage your computers, machinery, or other critical business equipment.
Smart Control System The PowerCommand 1.1 electronic control panel puts you in complete command. It automatically starts the generator when power fails, monitors performance, displays system status, and shuts down safely if any problems are detected. This system meets NFPA 110 Level 1 standards for emergency power systems.
Weather-Protected Design The green Level 1 sound enclosure shields the generator from the elements while significantly reducing operating noise. Whether it's rain, snow, or extreme temperatures, this enclosure keeps your generator running smoothly.
Extended Runtime Capability The built-in 132-gallon dual-wall subbase fuel tank provides 30+ hours of continuous operation at full load or 55-hours of run time at 50% load.
