Aurora Commercial Diesel Generators: Built for the Long Haul

When uptime matters, Aurora delivers. Our commercial diesel generators are engineered for harsh-climate reliability, clean electrical performance, and easy service, so your operation keeps moving when the grid doesn’t.

  • Industrial-grade power: 1800 RPM diesel platforms deliver low noise, excellent fuel economy, and long engine life.
  • Clean, stable electricity: Brushless, AVR-regulated 4-pole alternators protect sensitive electronics and start motors with confidence.
  • Your voltage, your way: Single-phase 120/240 V, or three-phase 120/208, 277/480, and 600 V options to match your building’s distribution.
  • Serious runtime: Built-in day tank standard, with optional sub-base tanks or separate 100/200-gal fuel tanks for extended operation.
  • Integration-ready: Two-wire auto-start and ATS compatibility streamline installation with any two-wire compatible transfer switch.
  • Service made simple: Thoughtful “cold-side” access, long service intervals, and widely available parts reduce downtime and cost.
  • Weather-tough enclosures: Open skid or sound-attenuated canopies designed for Canadian winters and year-round outdoor duty.
  • Compliance-minded: Built with UL/CSA-recognized components, ready for code-compliant installation by licensed electricians.

Why Aurora? Because we focus on the total cost of ownership, not just the first price. From premium components to expert support, our generators deliver dependable power, year after year.

Let’s power your facility. Tell us your load profile, preferred voltage, and runtime goals, and an Aurora power specialist will configure the right commercial generator for your site.

Construction

Aurora Generators are built to withstand the toughest conditions. Featuring heavy-gauge steel frames and fuel tanks, each unit is powder-coated for superior corrosion resistance. To ensure long-term durability, only stainless steel fasteners are used in assembly, preventing rust and wear over time.

Protection, Monitoring and Control

This 40 kW Perkins Diesel Generator is equipped with a DynaGen TG350 controller. The controller is designed to meet military specifications and is renowned for its ruggedness and ability to operate reliably in demanding environments.

Service Kits

Low Maintenance

Diesel generators have lower maintenance requirements compared to other types of generators. Specifically, the oil and filter only need to be changed every 500 hours of operation instead of every 100 hours for non-diesel generators. Aurora also carries a wide selection of parts and accessories for your generator.

5 Year Warranty on Aurora Generators

Flexible Warranty

The Aurora 15 kW Perkins Diesel Generator comes with a 5-year comprehensive factory warranty. Extended warranties are also available.

Fuel Nozzle

Cost Effective

A diesel-powered generator can save over $100.00 in fuel per day when used to power a home, compared to natural gas, propane, or gasoline. This is because diesel fuel has a higher energy density than other fuels, meaning less fuel is required to generate the same amount of power. For example, a typical home would use 0.5 gallons of diesel an hour, while it would need 4-6 gallons of propane to generate the same amount of power.

Diesel Fuel Tanks

Fuel Tank Options

This generator comes with a standard 50-gallon fuel tank. However, for those needing extended runtimes, larger fuel tanks are available, including both sub-base and standalone options.
