ANA AIRMAN 100 kW 125 kVA Mobile Diesel Generator Package with Highway Trailer (SDG125S-8E1)

The ANA AIRMAN SDG125S-8E1 125 kVA Mobile Diesel Generator Package delivers continuous, high-output three-phase and single-phase electrical generation engineered for commercial construction sites, municipal bypass operations, utility infrastructure maintenance, and emergency standby power. Driven by an EPA Tier 4 Final turbocharged 147.9 HP Isuzu BR-4HK1X liquid-cooled diesel engine, this mobile system provides 100 kW continuous prime output (110 kW maximum standby rating) while restricting operational noise down to an ultra-quiet 65 dB(A) at 23 feet.

Equipped with an integrated Smartload automated load bank system to prevent engine wet-stacking during low-demand cycles, color-coded CamLock power connections, and an electronic isochronous governor maintaining 60 Hz line frequency within ±0.25%, the SDG125S-8E1 provides stable, transient-free power across varying load profiles. Featuring a high-capacity 168-gallon onboard fuel cell delivering over 23.3 hours of runtime at full continuous load and mounted directly to a heavy-duty tandem-axle highway trailer (8,352 lbs GVWR), this turnkey mobile station ensures reliable continuous power in demanding field environments.

Recommended Jobsite Applications

  • Commercial Building & Infrastructure Projects: Running high-amperage temporary distribution panels, electric tower hoists, structural welding arrays, and high-volume site compressors.
  • Municipal Bypass & Utility Dewatering: Delivering uninterrupted 3-phase 208V, 240V, or 480V power to municipal sewage lift pumps, high-head trash pumps, and pipeline inspection stations.
  • Facility Emergency Standby: Providing automated 120/240V single-phase or three-phase emergency backup power to commercial refrigeration nodes, municipal yards, and clinics via transfer switch integration.
  • Remote Civil Engineering & Mining: Supplying continuous off-grid prime power for concrete batch plants, crushing operations, and temporary field offices.

Key Performance & Operational Features

  • Tier 4 Final Isuzu BR-4HK1X Engine: 5.2L 4-cylinder turbocharged, intercooled diesel delivers 147.9 HP with cooled EGR, DOC, and SCR aftertreatment to comply with stringent EPA clean air mandates.
  • Automated Smartload Load Bank System: Integrated system applies managed supplemental electrical load when site draw drops below critical thresholds, eliminating unburned fuel accumulation (wet-stacking) in the exhaust stream.
  • Complete Tandem-Axle Highway Trailer Package: DOT-certified transport trailer rated at 8,352 lbs GVWR equipped with highway-rated tires, electric brakes, an industrial front jack, and multi-hitch coupler options.
  • Multi-Voltage Distribution Selector: Lockable selector switch enables rapid manual reconfiguration across 3-phase 208V, 220V, 240V, 416V, 440V, and 480V, as well as single-phase line delivery.
  • Color-Coded CamLock Connection Panel: Dedicated exterior CamLock female receptacles provide fast, secure feeder cable hookups alongside standard terminal mechanical bus bars.
  • High-Capacity 168-Gallon Fuel Reservoir: Internal fuel tank provides extended runtimes of up to 23.3 hours at 100% full continuous prime load and over 43 hours at 50% load.
  • Complete Cold Weather & Remote Package: Factory-installed engine block heater, external 2-way auxiliary fuel tank piping, battery disconnect switch, and onboard automatic battery charger ensure operational readiness.
