Cat 3516C-HD SCR Gen-Sets Certified To Tier 4i

Posted on September 12, 2011

Caterpillar Inc. has announced the availability of the new Cat 3516C-HD diesel generator set, certified to meet United States EPA Tier 4 interim standards. The 60 Hz package is rated at 2500 kW for standby power, 2250 kW at prime power and 2050 kW at continuous power. Primarily applications are expected to be prime power, peak shaving, standby and mission critical applications, Cat said.

“Tier 4 interim certified generator sets are required for high-hour applications, such as rock crushers, peaking plants and remote installations,” said Robert Koval, global product director of Caterpillar Electric Power Division. “Our emergency standby customers will also realize benefits with this gen-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 Tier 4 interim certified generator set is optimized for use with the Cat clean emissions module. This aftertreatment system features a diesel oxidation catalyst combined with a selective catalytic reduction 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 Cat EMCP 4 control panel.
