Natural gas generator set for mobile applications

Caterpillar introduces XQ1250G natural gas mobile generator set.

Peoria, Ill., April 20, 2010—Caterpillar announces the availability of the XQ1250G natural gas mobile generator set. Sold and rented exclusively through Cat dealers, it is rated for continuous operation at 1,250 kW 480/277 V 60 Hz. The versatile Cat XQ1250G is an easily transportable, self-contained, natural gas power plant. It offers an easy-to-use control system to parallel with other Cat generators or with an electric utility.

“Many factors have contributed to development of Cat natural gas generator set rental units,” said Electric Power Rental marketing manager, Scott Heppner, Caterpillar Inc. “The industry is demanding cleaner, more efficient mobile power. Customers want to be able to meet both budget and sustainability targets. Given the rising demand for lower carbon fuels, increased gas pipeline availability and decreased natural gas pricing—the XQ1250G is a good fit for those in the market for 1MW+ mobile units.”

The XQ1250G power module employs a low emission G3516B engine with integrated exhaust after treatment to comply with July 2010 United States Environmental Protection Agency's New Source Performance Standard for Spark Ignited Engines (USEPA SI NSPS). If local emission requirements are more stringent, the XQ1250G product design is suitable for the addition of after treatment devices beyond the standard oxidation catalyst.

The G3516B operates on low pressure natural gas (3-7 psi) and is equipped with an active air-to-fuel ratio controller to allow for varying fuel energy content. With units generating millions of operating hours worldwide, the G3516B engine offers proven, best-in-class performance with low maintenance costs.

The G3516B engine, fuel regulation components, control and distribution system, and cooling package are housed in a sound-attenuated 40 foot ISO container. It is CSC-certified for nine unit high stacking. Greatly reducing installation time at the project site, the XQ1250G offers a fully integrated cooling and exhaust system. The operator can simply connect the natural gas supply line and the load cables to ready the unit for operation. The innovative design of the XQ1250G includes 100 percent spill containment of all engine fluids.

Caterpillar supports the XQ1250G through its’ worldwide network of independent dealers. Cat dealers provide complete rental solutions including engineering services, logistics, electrical distribution equipment, temperature control and compressed air solutions, and equipment service support. Extended service coverage options are also available.
