Combo Trailer Details

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 15 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.

Combo Trailer Applications

Built for industrial efficiency, the Combo Trailer eliminates the need to have a generator trailer, a light tower trailer, and a water trailer by combining them all into one. Built to DOT specifications, the generator water combo trailer is legal for road use and can safely be towed on highways and public roadways. This reliable industrial generator trailer is a preferred choice in providing power, light, and water to construction projects, oilfield work sites, camps, mobile offices, and even RVs.

For freeze protection for your water trailer or skid, our Water Trailer Heater Blankets are exactly what you need . When cold weather affects the viscosity of fuel, fluids, and other materials you can lose production time, adding additional costs. Power blankets keep your tanks and smaller corrugated/steel tanks at constant temperature, preventing fluids from freezing in extreme conditions. We customize thermal blankets to meet your specific needs, no matter the tank size or shape. Call us today to find out more!
