Marine Generator Sets

Industry-leading technology allows Caterpillar to create the most reliable commercial engines for a variety of applications. From tugs and container vessels to yachts and sport fishers, Cat and MaK engines have demonstrated their efficiency countless times. With remarkable reliability and durability, these engines will exceed your expectations for decades.

M 32 E Marine Generator Set

The M 32 E is designed for the offshore market focused on generator set application. The 720/750 rpm concept will reduce generator costs. Charge air cooler housing and charge air cooler allow easier disassembly and cleaning. The new design still supports operation at any ambient condition without load reduction. We offer a generator set application for customers operating the engines mainly below 47 %.
