| All models: L2SA enclosure, Diesel, 60 Hz. Wt = unit weight w/o fuel. Runtime at 100% / 75% / 50% load. | ||||||||||
Reduces radiated noise to approximately 65–75 dBA at 23 ft. Standard for commercial and institutional standby applications where noise ordinances apply.
Designed for severe weather environments. Higher ingress protection than Level 1. Adds dimension and weight relative to the open genset.
Suitable for most outdoor installations in moderate climates. The most common enclosure type for standby applications.
No enclosure. For indoor installations or where a custom enclosure is provided by others. Dimensions reflect the naked genset only.
Runtime figures are provided at 100%, 75%, and 50% load. Most models are available with a standard internal tank or an extended-length tank — the Long configuration adds to the overall unit footprint, which affects pad planning and clearances. Confirm tank selection before finalizing site dimensions.
For extended runtime beyond standard tank options, day tank and remote tank configurations are available on most models. Contact your application engineer.
Door swing figures reflect standard configuration. Lift-off doors are available on most models — contact your application engineer.
