Diesel Generators

To choose the right portable generator for your jobsite, you’ll need to consider power requirements (total wattage), fuel options (gas or diesel), decibel rating and any extra features you need. United Rentals offers a complete line of sound muffled diesel generators for remote site power or emergency backup. We have both towable and stand-alone units from 15.2 kW to 2,000 kW.

FAQs

What is the difference between an alternator and a generator?

  • A generator converts mechanical energy into either AC or DC electrical energy and can generate either alternating or direct current. An alternator converts mechanical energy into AC energy.

How many hours will a diesel generator last?

  • Generally, you can run a diesel generator up to 500 hours; however, the run time varies per unit, and you should refer to the product manual. If you have further questions, United Rentals experts are always here to help with any questions you have.

How much diesel does a generator use per hour?

  • Diesel fuel consumption depends on the generator’s size. Running on a full load, for example, a 20 kW generator will use about 1.6 gallons of fuel per hour and a 30 kW will use about 2.9 gallons of fuel per hour.
