Overview

Producing reliable power from 1640 to 2000 ekW at 60 Hz, our 3516B diesel generator sets are made to meet your mission critical, continuous, standby and prime applications. We've designed each to ISO 8528-5 transient response requirements and to accept 100 per cent rated load in one step. Generator sets offer both low fuel consumption and low emission systems.
