Dual Fuel Model Features:
- Natural gas is the primary fuel. Automatically transfers back to primary fuel when LPG fuel becomes low or generator stops and restarts.
- The patent pending reset box on the generator provides the ability to manually transfer back to natural gas.
- The natural gas rating is available when running on natural gas.
- APM603 controller provides load shed for automatic derate to LPG ratings to prevent an overload condition.
Generator Set Ratings
Note: All three-phase units are rated at 0.8 power factor. All single-phase units are rated at 1.0 power factor. Standby Ratings are applicable to varying loads for the duration of a power outage with no overload capability. Ratings are in accordance with ISO-8528-1 and ISO-3046-1. Consult technical information bulletin (TIB-101) for ratings guidelines, definitions, and site condition derates. Manufacturer reserves the right to change design or specifications without notice.
