Equipment Showcase: Diesel and Gas Generators

The need for reliable and resilient power generation, including backup power, means the market for mobile and smaller-scale power generation continues to grow. Commercial and industrial sites are using generators to produce power for their operations, often to ensure a constant flow of electricity in the event of an outage or to provide generation in remote locations. The prevalence of severe weather events in many locations in recent years also has contributed to growth not only in the commercial and industrial market, but also in the residential market. Though solar, wind, and energy storage are powering more facilities, natural gas and diesel are still the most common fuels for generator units. Some of the leading manufacturers and distributors for generators are featured here.

Jenbacher Unveils Fast-Start Gas Generator for Data Centers

Today’s data centers consume about 3% of the total energy generated globally and the challenge is to deliver that electricity in a more reliable and environmentally sound way. Helping to meet these needs, INNIO Jenbacher has announced the launch of its new Jenbacher J620 fast-start natural gas generator (Figure 1) for data centers. The company says the Jenbacher J620 not only delivers advantages for data center backup operations, but it also provides benefits when running parallel to the grid and in island mode. With built-in fuel storage, and with a natural gas connection, data center operators avoid limited run times and generator refueling. Compared to standby diesel-fueled generators, they also offer emissions reductions of up to 90% for nitrous oxide (NO x) and up to 25% for carbon dioxide (CO 2), giving users the flexibility of longer run times. The Jenbacher J620 provides full load in under 45 seconds, along with the additional benefits that come with the ability to run in a variety of operating modes. INNIO Jenbacher, Jenbach, Austria

Atlas Copco Power Technique features the QAS 625 (Figure 4), the newest and largest mobile generator in its lineup. With a power rating of 625 kVA/500 kW prime power, the fuel-efficient unit is compact, lightweight, and ideal for a wide range of applications including construction, mining, disaster recovery, general rental, and more. Equipped with a Volvo Penta 16.1-liter, 6-cylinder Tier 4 Final diesel engine, the QAS 625 runs at 724 horsepower. The highly reliable and durable Volvo engine features a selective catalytic reduction (SCR) exhaust aftertreatment system, simplifying the cost of ownership and maintenance. The unit requires less than two hours of service for every 500-hour service interval. A great solution to the most demanding jobsites, the motor starting capability is outstanding thanks to the AREP alternator excitation system. This provides 300% overcurrent starting capabilities coupled to the engine’s capacity to stand a 100% load step. Standard external fuel tank connections and dual fuel filters provide the ability to run extended periods without interruption in service. The internal 700-gallon fuel tank runs 27 hours. Camlocks and a battery charger also come standard, providing best-in-class performance for any rental application. Atlas Copco, Rock Hill, South Carolina

Cummins’ Line Includes Quiet Diesel Series
