Stewart & Stevenson: A Legacy of Dependable Power
Stewart & Stevenson has been a trusted name in industrial equipment for generations, and there's a good reason why. They've built their reputation by focusing on rugged, dependable solutions that can handle the toughest conditions. Whether it's powering offshore drilling operations in the Gulf of Mexico or keeping critical infrastructure running during natural disasters, Stewart & Stevenson generators have proven themselves time and again.
The company operates as both a manufacturer and distributor, partnering with globally recognized brands while maintaining their own high standards for quality and reliability. With service locations across Houston, Denver, Oklahoma City, Tampa, Fort Lauderdale, and Piscataway, they provide comprehensive support that includes 24/7/365 availability for emergency service calls.
This network of support is crucial because when your generator goes down, you need help fast. Stewart & Stevenson understands this, which is why they've invested heavily in their service infrastructure and parts availability.
Technical Specifications That Matter
The Stewart & Stevenson 250kW diesel generator we have in stock represents excellent value in the used generator market. Here's what makes this unit special:

Power Output: This generator delivers 250kW of reliable power (312.5kVA), making it ideal for medium to large commercial and industrial applications. That's enough juice to power a decent-sized manufacturing facility, a large office building, or serve as reliable backup for critical infrastructure.
Engine: At the heart of this unit is the proven Detroit 6V92TA engine. If you've been around industrial equipment for any length of time, you know Detroit engines have a reputation for durability and relatively straightforward maintenance. The 6V92TA is a two-stroke design that's been battle-tested in everything from heavy trucks to marine applications.
Operating Hours: With just 725 hours on the clock, this generator has plenty of life left. In generator terms, that's barely broken in. Most industrial generators are designed to run for tens of thousands of hours, so you're getting a unit with the vast majority of its service life ahead of it.
Electrical Configuration: The unit operates at 277/480V, three-phase, 60Hz at 1800 RPM. This voltage configuration is perfect for industrial applications and can easily integrate with most commercial electrical systems.
Fuel Capacity: The 200-gallon base tank provides excellent runtime between refueling. Depending on the load, this tank can keep the generator running for 8-12 hours or more, which is crucial during extended power outages.
Why This Model Stands Out
The enclosed design of this Stewart & Stevenson unit offers several advantages over open-frame generators. The weather-resistant enclosure protects the engine and alternator from the elements, which is essential for outdoor installations. The enclosure also provides significant sound attenuation, making it suitable for installations where noise is a concern.

The Detroit 6V92TA engine deserves special mention. While some people might hesitate when they hear "Detroit engine," those in the know understand that these engines have powered everything from city buses to industrial equipment for decades. They're designed for heavy-duty operation and, when properly maintained, can provide reliable service for many years.
The two-stroke design means fewer moving parts compared to four-stroke engines, which can translate to easier maintenance and potentially lower operating costs. Parts availability is generally good for Detroit engines, and there are plenty of qualified technicians who know how to work on them.
Perfect Applications for This Generator
This 250kW capacity makes this generator ideal for a wide range of applications:
Manufacturing Facilities: Small to medium-sized manufacturing operations can benefit from this level of backup power. It's enough to keep essential machinery running during outages while maintaining lighting and HVAC systems.
Healthcare Facilities: Medical facilities, surgical centers, and extended care facilities need reliable backup power for life-safety systems. This generator provides ample capacity for these critical applications.
Data Centers: Smaller data centers or server facilities can rely on this unit to bridge the gap during utility outages while UPS systems handle the immediate transition.
Construction Sites: For remote construction projects or sites where utility power isn't available, this generator can provide reliable primary power for tools, lighting, and temporary facilities.
Event Venues: Outdoor events, festivals, or temporary installations often need substantial power. This unit can handle the electrical loads for stages, lighting, and vendor booths.
The Swift Equipment Advantage
At Swift Equipment Solutions, we understand that finding the right generator is just the beginning. You need a supplier who can deliver quickly and stand behind what they sell. That's where we shine.
This Stewart & Stevenson 250kW unit isn't sitting in some distant warehouse – it's ready to ship. We maintain inventory levels that allow us to respond quickly to your power generation needs because we know that when you need a generator, you usually need it yesterday.

But this particular unit isn't the only option we have available. Our used generator inventory includes similar capacity units from other trusted manufacturers. Whether you're looking for Caterpillar, Kohler, or other premium brands, we likely have options that can meet your specific requirements and timeline.
Making the Right Choice for Your Operation
When evaluating used generators, there are several factors beyond just price that you should consider. The operating hours are important, but so is maintenance history. A well-maintained generator with higher hours might be a better choice than a neglected unit with lower hours.
The availability of service and parts is crucial. Stewart & Stevenson's extensive service network means you're not left stranded if you need maintenance or repairs. This is particularly important for critical applications where downtime has serious consequences.
Installation requirements are another consideration. This enclosed unit simplifies installation compared to open generators that might require separate weather protection. The integrated fuel tank eliminates the need for a separate fuel system, though you'll want to consider whether 200 gallons provides adequate runtime for your specific application.
Fuel Efficiency and Operating Costs
The Detroit 6V92TA engine in this generator is designed for efficiency within its power class. While fuel consumption will vary based on load, you can expect reasonable operating costs compared to other generators in this size range. The two-stroke design can provide good power-to-weight ratios, which was one of the reasons these engines were popular in mobile applications.
Regular maintenance is straightforward with Detroit engines, though you'll want to establish a relationship with a qualified service provider familiar with this engine family. Oil changes, filter replacements, and periodic inspections will keep this unit running reliably for years to come.
