Overview
1230 - 1500 ekW Diesel Generator Set
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.
FAQS
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.
Q. Does the Cat generator meet 10 second starting requirements?
A. Yes, with the appropriate configuration our generators are capable of 10 second starting to meet emergency needs or customer requirements.
