Caterpillar Introduces 3516C-HD Tier 4 Interim Certified Diesel Generator Set

Caterpillar's Electric Power Division recently introduced the new Cat® 3516C-HD diesel generator set, certified to meet U.S. EPA Tier 4 Interim standards. This 60 Hz package is rated at 2500 ekW for standby power, 2250 ekW at prime power and 2050 ekW at continuous power, offering highly efficient fuel consumption rates, compact footprint and lower emissions for prime power, peak shaving, standby and mission-critical applications.  

"This is the first diesel generator set producing more than 2MW that has been certified by the EPA," said Robert Koval, global distribution director of Caterpillar Electric Power Division. "Tier 4 Interim certified generator sets are required for high-hour applications, such as rock crushers, peaking plants and remote installations. Our emergency standby customers will also realize benefits with this generator set, particularly in areas with especially stringent local standards. The lower emissions from the Tier 4 Interim generator set should eliminate or minimize the amount of additional aftertreatment needed to comply with local emissions regulations."

The 3516C-HD is the latest addition to Caterpillar's line of Tier 4 Interim certified generator sets. Ranging from 455 kW to 2500 kW, Caterpillar offers the widest range of Tier 4 Interim certified generator sets in the industry.

To provide customers with the most economical and efficient emissions solutions, Caterpillar continues to develop generator sets engineered to deliver flexibility, expandability, reliability and cost-effectiveness, while at the same time addressing the emission reduction levels required by EPA regulations. The 3516C-HD Tier 4 Interim certified generator set is optimized for use with the Cat clean emissions module (CEM). This aftertreatment system features a diesel oxidation catalyst (DOC) combined with a selective catalytic reduction (SCR) module and an air-assisted urea injection system.

This diesel generator set also features integrated electronics for monitoring, protection and closed loop NOx control, an ADEM™ A4 controller, Air-to-Air After Cooler cooling system, MEUI fuel system and state-of-the-art Cat EMCP 4 control panel. This simple-to-use control panel delivers a more intuitive, user-friendly interface and navigation, and is scalable to meet a wide range of customer power requirements.

Available with a full range of factory designed and tested attachments, the 3516C-HD offers flexible packaging options for easy installation and optimal performance, while minimizing impact on generator set space requirements and maintenance hours. Cat Tier 4 generator sets are capable of integrating into larger power systems that could include UPS, Switchgear and ATS products. To support this new line of generator sets, Cat dealers and technicians will be factory trained in emissions technology installation and service.

Caterpillar is a leader in the power generation marketplace with power systems engineered to deliver unmatched durability, reliability and value. The company offers worldwide product support, with parts and service available globally through the Cat authorized service and dealer network. In addition, dealer service technicians are trained to service every aspect of Cat equipment.
