Overview

The 3512C diesel generator sets have been developed to meet your continuous, standby and prime applications. Producing reliable power of 1750 ekW at 60 Hz, each generator set is designed to meet ISO 8528-5 transient response requirements and accept 100 percent rated load in one step. Our 3512C generator sets operate to the EPA Stationary Emergency (Tier 2) emissions levels. Seismic certification is also available for selected models, maintaining your power after an unexpected disturbance. Our integrated control system, including ATS and switchgear ensures a consistent power supply and connection to your fleet through on site and remote monitoring options. Our EMCP 4 control panel options feature a user-friendly interface and offer management and diagnostic tools. The EMCP 4.4 controller provides multi generator set paralleling capability, giving you the ability to add generator sets to match your growing power requirements. It's not just quality that matters but customization, choose from a broad range of accessories and bolt-on system expansion attachments. Discover our upgradeable packaging options to work with your spatial restrictions and environmental conditions. Our 3512B generator sets are developed for such prerequisites, so that you can meet your specific power needs. For added safety select from one of the UL 2200 and CSA certified package options.
