75kW Diesel Generator Set

A 75kW diesel generator is priced by engine platform, configuration and alternator choice. At this rating H&C builds the Cummins R-DC91D6/S (4BTA3.9-G11 engine), rated 73 kW / 91.2 kVA prime and 80.3 kW / 100.4 kVA standby at 60Hz (1800 rpm). The price moves with the enclosure (open skid, soundproof canopy or containerized), the alternator (Stamford UCI224F or Leroy-Somer TAL-A44-C for the R-DC91D6/S), the controller and options such as ATS, and with the destination country and freight terms. Send your voltage, frequency and destination country and we will confirm the R-DC91D6/S price within 24 hours.

At 75% load a 75kW diesel generator consumes 13.5 L/h; at 100% load it rises to 18.0 L/h. The 4BTA3.9-G11 engine in the R-DC91D6/S works out at 207 g/kW·h per ISO 3046-1. Actual consumption on the R-DC91D6/S varies about ±5% with ambient conditions, load profile and fuel quality. At a diesel price of $1.0/L, running at 75% load costs roughly $14 per hour.

A 75kW set handles mid-size commercial and light-industrial loads in 60Hz markets: restaurants and supermarkets, small factories, clinics, mid-size construction sites and small pump stations. Standby is 80.3 kW / 100.4 kVA, which leaves starting margin for motor loads on top of the base load. Tell us your connected load and the largest motor you need to start and we will confirm whether 75kW or the next rating up fits better.

H&C supplies the 75kW rating on one engine platform: Cummins (R-DC91D6/S with the 4BTA3.9-G11 engine, 207 g/kW·h). Units ship as open skid, weatherproof silent canopy or 20ft/40ft container; the silent canopy for the R-DC91D6/S holds ≤75 dB(A) at 7m. All R-DC91D6/S units are built to 60Hz (1800 rpm) as standard, with custom controls and ATS available on request.
