Frequently Asked Questions About Towable Diesel Generators

1. What size towable diesel generator do I need?

Bigger is not always better. Oversizing a generator so it rarely reaches at least 30% load can shorten engine life and increase maintenance costs. Diesel engines are designed to work under load, and running too light for long periods can lead to issues like carbon buildup and wet stacking.

The goal is to size your towable diesel generator so it runs efficiently during normal operation, while still having enough headroom for short periods of higher demand. We help you match the kW rating to your tools, equipment, or facility so you get reliable performance and longer engine life.

2. How long will a towable diesel generator run on a tank of fuel?

These towable diesel generators use large 50-gallon sub-base fuel tanks. In most real-world applications, that provides up to 48 hours of runtime, depending on load. Lighter loads run longer, heavier loads use fuel faster.

A larger onboard tank means fewer refueling interruptions, better productivity on job sites, and longer protection during emergencies or remote work.

3. How loud is a towable diesel generator?

Modern towable diesel generators are often quieter than many standby units. They are engineered for environments where noise matters, using heavy, sound-attenuated enclosures that help reduce vibration and trap noise.

This makes them suitable for construction sites, events, commercial locations, and areas close to homes or businesses, without excessive noise complaints or disruption.

4. Are towable generators road-legal and highway ready?

Yes. These units are mounted on certified equipment trailers that are registered for legal use on North American roads. They are built to meet highway requirements and are safe to tow behind work trucks, service vehicles, and commercial fleets.

Because they are classified as equipment trailers, no license plate is required in either Canada or the United States. You can tow them to job sites, remote locations, or emergency deployments with confidence.

5. What voltage options are available? Can one generator handle different applications?

These towable diesel generators are built with dedicated voltage configurations instead of multi-voltage switching systems. That approach makes them more efficient, more reliable, and easier to use in the field. Most customers choose single-phase units, but dedicated three-phase models are available for commercial and industrial applications that require them.

Selectable voltage generators may sound convenient, but they introduce more complexity, reduce efficiency, and can increase maintenance over time. With a purpose-built configuration, you get stable, dependable power for the specific application you care about.

6. What engine and alternator brands are used, and are parts easy to get?

Towable diesel generators in this range use premium industrial components from brands that are well supported worldwide. They are powered by Perkins or Hatz diesel engines, both known for reliability, long service life, and strong parts availability.

For power generation, they use Mecc Alte alternators, one of the most respected names in the industry. These systems are engineered for professional use and meet CSA and UL standards, so you get proven performance and long-term serviceability across Canada, the USA, and beyond.

7. How reliable are towable diesel generators, and can they handle demanding environments?

These towable diesel generators are designed for serious work. Instead of trying to build one “fits everything” machine, each configuration is designed around a specific application so it performs better, runs cleaner, and lasts longer.

They are built for professional use, harsh job sites, long runtime needs, and demanding environments where downtime is not an option.

8. What maintenance is required, and who can service a towable diesel generator?

Routine maintenance is straightforward. Follow the recommended service schedule and most owners can handle basic maintenance like oil and filter changes themselves. These generators include convenient features such as 1/4-turn ball valves for easy oil draining and spin-on filters to speed up service work.

Because they use well-known Perkins and Hatz diesel engines along with globally supported components, service and parts are widely available. You are not locked into a proprietary dealer network; any qualified diesel technician, fleet service shop, or equipment service center can work on the unit if needed.

9. What protection and monitoring features are included?

These towable diesel generators use DynaGen digital controllers to manage, protect, and monitor the entire system. You get full instrumentation along with automatic safety shutdowns for conditions like low oil pressure, high coolant temperature, overspeed, and other critical events.

The controller also makes operation simple, with clear status information and fault history that help operators keep the generator running safely and reliably in the field.

10. Is it better to rent or own a towable diesel generator?

Owning a towable diesel generator often makes far more financial sense than renting. Rental companies keep their generators in service for many years because they are profitable assets that pay for themselves many times over. The same economics work in your favor when you own instead of rent.

By investing in your own generator, you avoid ongoing rental fees, availability issues, and scheduling hassles. You control your equipment, reduce operating costs over time, and gain a dependable power source you can use whenever you need it. For businesses that use generators more than occasionally, ownership almost always delivers better long-term value.
