3512B Diesel Generator Sets

DESCRIPTION

1230 - 1500 kW at 60Hz Diesel Genset
Our industrial diesel generators produce reliable power from 1230 to 1500 kW at 60 Hz. The 3512B diesel gensets are made to provide continuous power solutions for your business operation as well as supply standby and emergency power. Diesel engines are parallelable and meet prime applications. We've designed each to ISO 8528-5 transient response requirements and to accept 100% rated load in one step. Cat® generators are available in low fuel consumption and low emissions configurations.
