ANA AIRMAN 320 kW 400 kVA Mobile Diesel Generator Package with Highway Trailer (SDG400S-8E1)
The ANA AIRMAN SDG400S-8E1 400 kVA Mobile Diesel Generator Package delivers continuous, high-capacity three-phase and single-phase electrical output engineered for municipal infrastructure bypass, utility substation emergencies, large-scale commercial civil projects, and critical industrial operations. Driven by an EPA Tier 4 Final turbocharged 457.7 HP Isuzu 6WG1X liquid-cooled diesel engine, this mobile system provides 320 kW continuous prime output (336 kW maximum standby rating) while restricting operational noise down to an ultra-quiet 68 dB(A) at 23 feet.
Equipped with proprietary Delta Demand Excitation for high inductive motor-starting capacity and an electronic isochronous governor maintaining 60 Hz frequency regulation within ±0.25%, the SDG400S-8E1 automatically balances magnetic excitation across severe cyclic tool demands without line voltage drop. Featuring a high-capacity 491-gallon onboard fuel cell delivering over 21.3 hours of runtime at full continuous load and mounted directly to a heavy-duty highway trailer (19,602 lbs GVWR), this mobile system provides utility contractors, plant managers, and civil crews with turnkey power generation for demanding applications.
Recommended Jobsite Applications
- Utility Substation & Grid Bypass: Supplying continuous high-amperage 480V or 208V power to maintain grid operations during scheduled utility maintenance and emergency outages.
- Municipal Water & Wastewater Treatment: Powering large multi-hundred-horsepower high-head raw water pumps, centrifuges, and aeration blowers during municipal repairs.
- Large-Scale Civil & Infrastructure Projects: Running high-capacity electric tower cranes, central batching plants, multi-operator structural welding banks, and underground tunnel ventilation fans.
- Industrial Facility Emergency Standby: Providing automated prime power for cold storage logistics hubs, manufacturing processing plants, and telecommunication data centers via automatic transfer switch (ATS) integration.
Key Performance & Operational Features
- Tier 4 Final Isuzu 6WG1X Engine: 15.7L 6-cylinder turbocharged, charge-air cooled diesel delivers 457.7 HP with cooled EGR, DOC, and SCR aftertreatment to comply with stringent EPA clean air mandates.
- Delta Demand Excitation Technology: Automatically manages magnetic excitation levels to handle high motor-starting inrush spikes, preventing terminal voltage drops during heavy inductive tool starts.

💡 MOTOR STARTING & RUNTIME SIZING TIP: Sizing large 480V inductive motor loads through the SDG400S-8E1 takes full advantage of the Delta Demand Excitation system. When staging primary distribution for high-horsepower municipal bypass pumps, establish a steady-state baseload of at least 30% to maintain clean exhaust temperatures in the Tier 4 Final SCR catalyst and ensure the 21.3-hour runtime profile of the 491-gallon fuel reservoir.
