Cummins C12D6RE — 12kW Mobile Diesel Generator
12kW standby, 10.8kW prime. Rental fleets and contractors: job-site offices, tool power, light towers and small temporary services.
12 kW standby EPA Tier 4 Final 26 gal tank ~29.5 hr runtime 62 dB(A) at 20 ft, half load
The C12D6RE arrives as a complete, self-contained power plant: engine, alternator, controls, fuel and distribution panel in a sound-attenuated, lockable enclosure on its own trailer. Park it, connect the load and start it. There is no pad to pour and no gas line to run.
It runs a Kubota D1503-M, 1.5 L in-line 4-cylinder, liquid-cooled certified to EPA Tier 4 Final. The onboard 26 gallon tank gives about 29.5 hours at 75% of prime load.

The C12D6RE is sold by UTS ElectricPros, an authorized Cummins dealer in Dallas–Fort Worth. Buying through an authorized dealer is what keeps the manufacturer warranty valid — equipment bought from an unauthorized reseller frequently is not covered, and owners tend to find that out at the worst possible moment.

Connecting it to a building?
A trailer generator feeds a building through a transfer switch or a generator docking station, installed by a licensed electrician. That is not part of the equipment sale. In Dallas-Fort Worth we quote it in writing after a free site survey.

Questions about the C12D6RE
How much is the Cummins C12D6RE?
The C12D6RE is $20,617.50 for the equipment, the same at every voltage it is offered in. Freight is not charged at checkout: it is quoted per shipment, and we confirm it with you by phone before anything is booked. Paid by bank transfer (ACH) at checkout, or by wire on invoice. No card fee. Sales tax is calculated at checkout from the delivery address. No installation is included or required to run it as a stand-alone generator.
Can we buy the C12D6RE for a rental fleet?
Yes. This is a Cummins rental package, built for fleet use: a lockable enclosure, onboard fluid containment and controls designed for rental operators. Rental companies and commercial buyers can order online or by phone. Tax-exempt purchases require a valid Texas resale or exemption certificate. Without one on file, sales tax is charged at checkout. To buy tax-exempt, provide your certificate before ordering by calling (214) 957-4307; online checkout cannot accept a certificate. Orders for several units are also easier to arrange by phone.
Which voltage should I choose?
The C12D6RE is a 120/240 1Ph unit, which covers standard 120 V and 240 V tools, job-site panels and single-phase loads. It is not offered in a three-phase build.
How long will the C12D6RE run on a tank?
The onboard tank holds 26 gallons, which Cummins rates at about 29.5 hours at 75% of prime load. At full standby load it burns 1.28 gallons an hour.
What do I need to tow the C12D6RE?
It weighs 1,801 lb dry and 2,017 lb with a full tank, about 1 tons, on a single-axle trailer. Check your tow vehicle and hitch against the wet weight, not the dry weight.
Can the C12D6RE power a building?
Yes, but not by plugging it in. Connecting a generator to a building's wiring needs a properly rated transfer switch or generator docking station installed by a licensed electrician, so the generator cannot back-feed the utility line. That work is not sold with the equipment. In Dallas-Fort Worth we quote it separately after a site survey.

What it is for
Temporary power at scale, towed to site
A site needs real power before there is a service to connect to, or needs it only for a while: a jobsite, an event, a planned utility shutdown, or a building running on temporary supply during a fit-out. Buying a permanent set for a temporary need is the wrong purchase.
Why it becomes urgent
For a rental company the problem is different and simpler: units on the yard that are not earning.
Who buys it
Equipment rental companies buying fleet units, and contractors powering a site directly.
Before you buy the C12D6RE
The questions that decide whether this is the right machine, answered properly rather than in a sentence on a product page.
- Is 12kW the right size for the load?Size against the connected load and the starting surge, not the floor area.
- Why diesel rather than natural gas?Fuel decides runtime, refueling and what the gas side of the install costs.
- How loud is it, really?Published dB by model, and what that sounds like from a neighbor’s window.
