100kW 125KVA Cummins Industrial Generator Set QSB5.9-G3 is suitable for factories, workshops, farms, construction sites, commercial buildings, cold storage facilities, and emergency backup power systems that need reliable 50Hz diesel generator set output.
The TPD140C5 configuration provides 125 kVA / 100 kW prime power and 140 kVA / 112 kW standby power, giving about 12% standby kW reserve for motor starting, pump loads, compressor loads, HVAC equipment, and emergency backup demand.
The Cummins QSB5.9-G3 engine uses a 6-cylinder inline 5.9L platform, giving this 100kW generator set dependable displacement and load response for industrial power applications.
Fuel consumption is 31 L/h at rated output, equal to about 0.310 L/kWh at 100kW load; for an 8-hour working shift, diesel planning is about 248 L, helping customers estimate daily operating cost before purchase.
The open type generator set footprint is about 1.98 m2 with 1150 kg weight, making it practical for generator rooms, equipment shelters, trailers, and industrial power systems.
The silent type generator set footprint is about 3.66 m2 with 1750 kg weight, giving customers a lower-noise Cummins generator set option for commercial backup power, outdoor standby power, farms, and construction sites.
Compared with choosing an oversized 160KVA generator set for a 70kW to 90kW working load, this 125KVA generator set can reduce equipment size, installation space, and fuel storage pressure while keeping standby reserve.
The recommended DSE7320 MKII DeepSea controller supports AMF auto-start, generator monitoring, shutdown protection, alarm display, and easier daily operation for customers who need automatic backup power during grid failure.
The 125kVA brushless alternator configuration with 400/230V, 3 phase 4 wire, 0.8 power factor, AVR voltage regulation, Class H insulation, and IP23 protection supports pumps, fans, compressors, lighting, HVAC, and general industrial loads.
