Thermo King SG-4000 Undermount Genset

The Thermo King SG-4000 is an undermount container generator set built to exceed EPA Tier IV and CARB emission requirements, and rated to power any ISO reefer container at 15 kW. It mounts beneath a container chassis and supplies the 440-480 volt, three-phase, 60 Hz power a refrigerated container needs in transit. Listed at $9,500. Thermo King SG-4000 Specifications Output: 15 kW, 460/230 V AC, 3-phase, 60 Hz — full ISO reefer power compatibility Emissions: exceeds EPA Tier IV and CARB requirements Mounting: undermount, standard container chassis Engine: heavy-duty Thermo King diesel with high-capacity cooling Controls: SG+ microprocessor controller with stable voltage control Protection: guarded rotating components, enclosed electrical connections Condition: new and used units available Price: $9,500 “Full ISO Power Requirement” — What That Means A refrigerated ISO container is designed around a defined supply: 460 volts, three phase, 60 Hertz, with enough capacity for compressor starting current on top of running load. Fifteen kilowatts is the figure that satisfies it with margin. A genset that produces 15 kW on paper but sags under motor inrush will not hold a reefer through pull-down, which is why the ISO compatibility claim is worth more than the nameplate rating alone. Emissions Headroom Buying a genset that exceeds current requirements rather than merely meeting them is cheap insurance. Emissions rules for non-road engines have tightened steadily, CARB has repeatedly moved first, and a set that only just satisfies today’s standard is a set you may be arguing about in five years. The SG-4000’s headroom is a large part of what you are paying for. Applications Reefer container drayage, intermodal and port haulage, and fleets running California lanes where CARB compliance is checked.
