For rental fleets and commercial buyers

Cummins mobile trailer generators

5 towable diesel generators from 12kW to 200kW, from $20,617.50. Each is a complete power plant on its own DOT trailer: engine, alternator, controls, fuel and distribution panel in a lockable, sound-attenuated enclosure. These are Cummins rental packages, sold to rental companies adding fleet units and to businesses buying power for a specific commercial job: construction, events, disaster response, or a facility whose service is down or being replaced.

Before you order

Fleet orders and tax-exempt purchases

Tax-exempt purchases require a valid Texas resale or exemption certificate. Without one on file, sales tax is charged at checkout. Online checkout cannot accept a certificate, so to buy tax-exempt, or to order several units, call (214) 957-4307 and provide the certificate before you order.

Choose the voltage at the order

The larger units are built to the voltage you select, from 120/240 V single phase to 277/480 V three phase, and Cummins configures them before they ship. Match the selection to what you will power. If you are not certain, ask your electrician or call us first.

Check the tow weight wet, not dry

A full tank adds hundreds of pounds, and on the 150kW and 200kW units the trailer weighs about five tons fueled. Rate your truck and hitch against the weight with fuel. On the 70kW through 200kW trailers you choose electric or hydraulic brakes and a ball or pintle hitch when you order.

Tier 4 Final means DEF

The 70kW through 200kW sets meet Tier 4 Final without a diesel particulate filter, so there is no DPF to regenerate, but they do use diesel exhaust fluid. Keep DEF on hand alongside the fuel.

Powering a building needs an electrician

A trailer generator connects to a building through a transfer switch or a generator docking station, never by back-feeding a panel. That installation is a separate job. In Dallas-Fort Worth we quote it after a free 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.
