Overview#
The Airman EBOSS 220-125 is a diesel-battery hybrid energy system combining a 220 kVA Airman generator with 125 kWh of Lithium Titanate Oxide (LTO) battery storage. A large-frame hybrid for major construction sites, temporary facilities, and data center temporary power where fuel cost and emissions matter. At 176 kW prime / 194 kW standby, the EBOSS 220-125 delivers the same power class as Airman's conventional SDG220S but with dramatically lower fuel consumption and the ability to operate silently on battery during noise-restricted periods. The 125 kWh battery bank can carry significant loads independently, with the John Deere 6068 diesel engine activating only when battery state-of-charge requires it.
Features unlimited parallel capability. LTO battery chemistry for superior cycle life. Built by Hokuetsu Industries in Japan with 110% fluid containment.
EBOSS Hybrid Technology at 220 kVA#
The EBOSS 220-125 pairs a John Deere 6068 diesel engine with a 125 kWh LTO battery bank — the second-largest battery configuration in the EBOSS lineup. At this scale, the hybrid system delivers meaningful fuel savings on large sites where conventional diesel generators run continuously but rarely at full load. The 125 kWh battery capacity allows the system to absorb significant load variations without starting the diesel engine, and when the engine does cycle on, it runs at its most efficient operating point rather than at whatever partial load the site happens to demand. For data center temporary power applications, the EBOSS 220-125 offers a compelling advantage: battery-backed power with seamless diesel supplementation, providing both the reliability of a diesel generator and the instant response of battery storage during load transients.
Our Service Experience#
The EBOSS 220-125 is our large-frame hybrid solution for major construction and data center projects. At 176 kW prime, it handles the same building-scale loads as our conventional SDG220S fleet — full HVAC systems, elevator banks, and multi-floor electrical distribution — but with the fuel and noise advantages unique to the EBOSS platform. We have deployed it on data center commissioning projects in Santa Clara and Fremont where the combination of reliable power delivery and reduced emissions was a project requirement.
Maintenance on the diesel engine follows the standard 250-hour oil change schedule for the John Deere 6068 platform. The 125 kWh LTO battery system requires minimal maintenance — periodic visual inspection of connections, cooling pathways, and battery management system status. The reduced diesel engine operating hours translate directly to lower fuel costs, fewer oil changes per calendar year, and reduced wear on engine components. For long-term deployments, the EBOSS 220-125 delivers a measurably lower total cost of ownership compared to running a conventional diesel generator on the same variable-load application.
