If you think you know the Cat® C4.4 ACERT™ marine generator set, think again. The latest model is all new — and the updates combine to deliver better performance, lower costs and easier operation aboard your vessel.
New fuel system for clean, reliable operation
The C4.4 ACERT now features a common rail fuel system that generates all the power you need for onboard operations with less fuel burned and fewer emissions generated. This electronic engine is extremely reliable, exceptionally quiet and virtually smoke-free.
New cooling system for simpler installation
The days of needing two keel coolers are over. With its single-circuit cooling system, the new C4.4 ACERT allows for plug-and-play installation on new or existing vessels. Repowering? Use your current keel cooler to save time and money.
