3512 with Upgradeable Package

The 3512 diesel generator sets with ugradeable packaging have been developed to meet your mission critical, continuous, standby and prime applications. Producing reliable power from 890 to 1250 eKW 60 Hz, each generator set is designed to meet ISO 8528-5 transient response requirements and to accept 100 percent rated load in one step. Our integrated control system keeps you connected through on-site and remote monitoring options. We offer easy-to-use EMCP control panel options, combining your management and diagnostic tools in one step. The EMCP4 control panel provides a flexible control platform, with an easy-to-use display — it's your single source for management and diagnostics 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 flexible packaging options to work with your spatial restrictions and environmental conditions. Our 3512 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.
