Overview
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. Generator sets offer efficiently lower fuel consumption and emissions.
Q. Can we burn HVO (hydrotreated vegetable oil) in this generator to help achieve our Sustainability goals?
A. Yes, the 3512B can burn HVO to help reduce emissions.
