Combo Trailer Details

This trailer is also a great solution for disaster response and emergency situations, where clean water, electricity, and lighting may be hard to find. It’s recommended for towing with a 1-ton truck or larger.

This generator water combo trailer provides portable power, water and light for just about any jobsite that is accessible by road. No need for several industrial trailers on the job site when one will do. The 500 gallon water tank transports potable water to the project location, while the industrial trailer's mounted diesel generator supplies the electricity. The water supply system utilizes a pressure tank to reduce pump cycling and provide a steady flow of water. For cooler climates, the (optional) Freeze Protection Package protects the water components, allowing longer seasonal use in the field.

The 20 kW Allmand generator is supplied with fuel from the attached 240 gallon diesel tank. When full, this generator trailer with fuel tank can run up to 300 hours. The attached 25' LED light tower illuminates the job site, extending the workday for evening or early morning crews.

The light tower trailer is also equipped with a step, handholds, and slip-resistant treads for easy access to the light tower mast and outlets. The industrial trailer uses a drop leg jack and outrigger jacks for stabilization. Additionally, there is a freeze protection module available that protects the combo trailer's water components in cold weather, further extending the season that the unit can be deployed in the field.

Frequently Asked Questions

Can this industrial trailer be towed on public roads?

Yes, this generator trailer is DOT compliant for highway use. It has surge brakes, lights, breakaway chain, and other safety features included in the package. Please see the trailer specifications above for a complete list.

Why is the 500 gallon water tank black?

The black tank on this generator water combo trailer makes it algae resistant. The color of the tank helps create a climate inside the tank itself that is less favorable for algae to grow.

Is this tank safe for drinking water transportation?

Yes, this water tank uses only components that are rated as safe for use with potable water. Please note, the water tank is only for use in water storage and transportation. It is not rated for use with other liquids. The diesel tank for the generator is located separately, beneath the water tank.
