It delivers 12500 peak watts or 9500 running watts when using gasoline and scales down for propane and natural gas. Key attributes include remote start via a key fob, a transfer switch-ready configuration, and automatic safety features such as low-oil and carbon monoxide shutdown. Its design accommodates two GFCI 120V outlets, plus an L14-30R transfer switch receptacle and a 14-50R RV outlet, with rubber outlet covers for outdoor use. The unit emphasizes long service life through a cast-iron engine sleeve and a digital hour meter for maintenance planning. Runtime depends on selected fuel and tank size, making it suitable for mid-size facilities needing dependable standby power or on-site temporary support during outages.
Westinghouse 14500 Peak Watt Tri-Fuel Generator
The Westinghouse 14500 Peak Watt Tri-Fuel unit targets larger-load scenarios with up to 14500 peak watts and 11500 running watts on gasoline, plus proportionally strong figures for propane and natural gas. It is built around a heavy-duty 550cc OHV engine with a cast-iron sleeve, designed for extended runtimes on a sizable 9.5-gallon tank and weather-resistant outlets. With a 19-hour potential runtime on gas and propane durations of similar length, operators gain substantial flexibility for emergency power, job-site needs, or remote operations. The model features remote electric start, a durable enclosure, and a full complement of transfer switch outlets, including an RV-ready option, all with safety-minded rubber covers and a digital hour meter for maintenance scheduling.
Westinghouse 13500 Peak Watt Tri-Fuel Generator
This Westinghouse model sits between the 12500 and 14500 offerings, delivering 13500 peak watts and 10500 running watts on gasoline, with solid performance for natural gas at 10000 peak / 8500 running watts. It includes remote start, a robust 500cc Westinghouse engine, and a long runtime profile with a 9.5-gallon fuel tank and gauge. The unit emphasizes safety and user protection with automatic low-oil shutdown, CO shutdown, and sealed outlets that stay clean in varied conditions. It targets industrial users who need reliable tri-fuel capability and a broad set of outlets, including L14-30R and 14-50R configurations for transfer switches and heavy loads.
WEN 14,500-Watt Tri-Fuel Generator
The WEN TF1450X stands out for seamless fuel-switching among gasoline, propane, and natural gas. It operates at both 120V and 240V, making it well-suited for transfer switches and emergency back-up across industrial settings. Its CO watchdog sensor adds a safety layer by automatically shutting down during unsafe carbon monoxide conditions. The unit is positioned as a practical solution for job sites or facilities needing a larger tri-fuel generator with a straightforward fuel selection process and a strong set of protective features. The included transfer-switch readiness enhances its appeal to more complex electrical setups.
DuroMax XP13000HXT Tri Fuel Generator

This model is suitable for facilities needing strong peak power and reliable operation on either gasoline or propane, with a focus on simplicity in startup and integration into larger electrical systems.
Buying Guide
- Fuel flexibility: Tri-fuel units offer the most versatility for industrial sites facing fuel supply variability. Assess the availability and cost of natural gas, propane, and gasoline in your area.
- Power profile: Compare peak watts for startup surges and running watts for continuous loads. Industrial workloads often require higher peak capacity and sustained power for critical equipment.
- Runtime and fuel capacity: Larger tanks and efficient engines extend runtimes between refueling. Look for units with fuel gauges and clear maintenance indicators.
- Safety features: CO detectors or CO shutdown, low-oil shutoffs, and protected outlets improve operator safety. Remote start and battery-based electric start reduce manual handling time during outages.
- Transfer switch compatibility: Ensure the generator supports standard transfer-switch configurations (L14-30R, 14-50R) and is interlock-ready if you plan to run it with utility-grade panels.
- Noise and emissions: Inverter-based tri-fuel generators tend to run cleaner and quieter, which matters for installations near workplaces or residential-adjacent facilities.
- Maintenance and warranty: Look for models with durable engine components (cast-iron sleeves) and clear maintenance schedules, as well as solid warranty coverage for industrial use.
- Portability vs. stationary needs: Some units are designed for frequent relocation, while others are intended for fixed installations with durable frames and wheels for site mobility.
- System integration: For industrial use, prioritize models with clear electrical diagrams, remote-start options, and compatible accessories to simplify integration with existing electrical systems.
