New | 3516B Generator Set

The 3516B diesel generator sets are made to meet your mission critical, continuous, standby and prime applications. Producing reliable power from 1750 to 2500 kVA at 50 Hz, each generator set has been 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. 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. Find flexible packaging to fit unique spatial requirements and environmental conditions. Our 3516B generator sets are developed for such prerequisites, so that you can meet your specific power needs.
