Questions
Why choose diesel for a business?
Diesel is stored on site, so the generator does not depend on the gas utility during the event that took the power out. It offers high power density, and the C-series runs at 1800 rpm, half the engine speed of a residential air-cooled unit, which suits long runs.
What is the difference between the enclosed and open C-series?
Enclosed models come in a Sound Level 1 enclosure, with or without a 24-hour base tank, and sit outdoors on a pad. Open-frame models have no enclosure and go in a generator room, a farm building, or a yard where you provide the housing. Cummins also sells the open-frame range as its agricultural standby line.
Can I buy a light commercial generator online?
Yes, for the enclosed models with a published price. Add the configuration to the cart and check out. Freight on the C-series is quoted per shipment and confirmed by phone before it is booked. Open-frame models and anything above 100kW are quoted per project on (214) 957-4307.
Do you install commercial generators?
In Dallas-Fort Worth, yes, under Texas electrical contractor license TECL #40628. Installation is quoted separately after a site survey covering the pad, fuel arrangement, transfer switch and permits. The equipment can be shipped anywhere in the United States.
