  • Overview

    The 3516C diesel generator sets have been developed to meet your continuous, standby and prime applications and match your power standards. Producing reliable power from 1650 to 2500 ekW at 60 Hz, each generator set has been designed to meet ISO 8528-5 transient response requirements and accepts 100 percent rated load in one step. Depending on the model, 3516C generator sets are EPA Stationary Emergency (Tier 2) or Tier 4 Interim certified. With industry leading innovation our Tier 4 Interim models have emissions reduced up to 90 percent — it's technology that has benefits well beyond todays regulations. Seismic certification is also available for select models, maintaining power after unexpected disturbances. The integrated control system, including ATS and switchgear, ensures a consistent power supply and connection to your fleet through on-site and remote monitoring options. With an user friendly interface our EMCP 4 control panel provides flexible options putting your management and diagnostic tools in one. The EMCP 4.4 controller provides multi-generator set paralleling capability, giving you the ability to add generator sets to provide expanded capacity and generator set redundancy to match your requirements. As no two power requirements are the same we offer a broad range of accessories and bolt-on system expansion attachments. Find flexible packaging options to work with your spatial requirements and environmental conditions. Our 3516C generator sets are developed for such prerequisites, so that you can meet your specific power needs — customize them to match your requirements. For added safety select from one of the UL 2200 and CSA certified package options.
