When you need reliable, industrial-grade power that won't let you down, few names carry the weight that Cummins does. For over a century, Cummins has been the go-to choice for mission-critical power applications worldwide, and their DFGB VTA28-G5 diesel generator is a perfect example of why that reputation is so well-deserved.

At Central States Diesel Generators, we're proud to have several used Cummins DFGB VTA28-G5 units in stock and ready for immediate shipment. Let's dive into what makes this generator such a standout choice and why it might be exactly what your operation needs.

Why Cummins Leads the Industry

Cummins didn't become a household name in power generation by accident. They've built their reputation on three core principles: reliability, performance, and innovation. When you see that familiar red logo, you know you're getting equipment that's been tested in the most demanding conditions imaginable.

The company has been powering everything from backup systems for hospitals to continuous-duty operations at mining sites. That kind of track record doesn't happen overnight – it's the result of decades of engineering excellence and real-world performance validation.

What sets Cummins apart is their commitment to building generators that keep running when everything else stops. Whether you're dealing with extreme temperatures, high altitudes, or round-the-clock operation, Cummins engines are designed to handle it all without missing a beat.

Technical Specifications That Matter

The DFGB VTA28-G5 isn't just another diesel generator – it's a powerhouse engineered for serious applications. At its heart is a 12-cylinder, 4-cycle diesel engine that delivers impressive performance across the board.

Power Output and Performance:

  • 900 horsepower at 1800 RPM (60Hz configuration)
  • 750 horsepower at 1500 RPM (50Hz configuration)
  • 600 kW standby output with 545 kW prime power rating
  • Engine displacement: 28 liters (1,710 cubic inches)

Engine Configuration:

  • 40° V-12 cylinder design
  • Bore and stroke: 5.5 x 6.0 inches (140 x 152 mm)
  • Compression ratio: 13.1:1
  • Turbocharged and aftercooled for maximum efficiency

The VTA28-G5 features dual large-capacity aftercoolers that significantly improve combustion efficiency, while dual camshafts provide precise control over valve and injector timing. This isn't just technical jargon – these features translate directly into better fuel economy, lower emissions, and more reliable operation.

Smart Engineering Features

One of the things we love about the VTA28-G5 is how Cummins engineered it with real-world operation in mind. The PT (Pressure-Time) fuel system is self-adjusting, which means less maintenance headaches for you. The integral dual flyweight governor provides overspeed protection – a critical safety feature that gives you peace of mind during operation.

The cooling system is another standout feature. Cummins designed it with improved coolant flow around cylinder liners, valves, and injectors, plus a large-capacity gear pump that provides pressure lubrication to all bearings. This might sound like inside-baseball technical stuff, but it's actually the foundation of the engine's legendary reliability.

Generator Set Configuration and Options

The DFGB package comes loaded with features that make installation and operation straightforward:

Electrical Specifications:

  • 277/480V, 3-phase, 60Hz output
  • 12-lead reconnectable configuration for flexibility
  • PMG (permanent magnet generator) alternator for consistent power quality
  • PowerCommand digital control panel for easy monitoring and control

Standard Features:

  • Weather-resistant enclosure for outdoor deployment
  • 1000-1200 Amp main-line circuit breaker (varies by specific unit)
  • 24V electric starter system
  • Engine coolant heater for cold-weather starting
  • Sub-base fuel tank with secondary containment (250 to 1,600 gallons depending on unit)

The PowerCommand control system deserves special mention – it's intuitive enough that your operators won't need a degree in electrical engineering to use it, but sophisticated enough to provide all the monitoring and protection features you need for professional operation.

Versatile Power Ratings for Any Application

One of the biggest advantages of the VTA28-G5 is its flexibility. This engine can operate under Prime (PRP), Standby (ESP), and Continuous (COP) power ratings, making it suitable for virtually any industrial application you can think of.

Prime Power Applications:
Perfect for situations where the generator will be your primary power source for extended periods. Think remote construction sites, temporary facilities, or locations where grid power isn't reliable.

Standby Power Applications:
Ideal for backup power systems at hospitals, data centers, manufacturing facilities, or any critical operation that can't afford downtime during grid outages.

Continuous Power Applications:
Built to handle 24/7 operation in applications like mining operations, oil and gas facilities, or industrial processes that never stop.

Performance You Can Count On

The VTA28-G5 operates reliably up to 4,000 feet elevation and 104°F (40°C) ambient temperature without any power derating. That's the kind of performance specification that matters when you're dealing with challenging installation environments.

Cummins has a saying: "Recognized globally for its performance under even the most severe climatic conditions." That's not marketing fluff – it's a statement backed up by thousands of installations worldwide operating in everything from Arctic conditions to desert heat.
