We offer a full range of standard marine alternators, alongside custom-made marine alternators to suit any vessel.

Our standard machines are equipped with high performance features and class-leading efficiency to suit marine applications, with 12-wire reconnectable winding that can handle all the standard various voltage and frequency requirements.

Custom builds and designs are also available including dedicated windings like the 690V 50/60Hz for windfarm support vessels or small compact designs for use where space is at a premium.

If the application demands more than the standard marine insulation, then we have a number of additional protection systems to choose from.

The most advanced insultation system is developed with harsh environments in mind. This V-Type insulation system adds class-leading resilience in harsh environments, all backed by an extended manufacturer’s warranty.

Mecc Alte marine alternators incorporate standard features to meet primary marine requirements, including the MAUX Power Boost Auxiliary System providing >300% short circuit maintenance, IP23 ingress protection. All alternators incorporate low reactance values in order to handle sophisticated marine loads and drives.

With a modular design system, upgrades such as IP43 and IP45 protection levels can be provided. IP45 is often requested in the latest water-based fire-fighting systems. In addition heaters and sensors can be retrofitted.

Most ECO and ECP Marine Range models have full type approval from Bureau Veritas (BV) and DNV. For other classification societies, type approval has been obtained for selected products within the range. Full marine classification and project-specific certification can be supported with all major classification societies upon request.

Type approval coverage by product and classification is detailed in the Type Approval Matrix, available for download below.

Alternators have BV type approval as standard, and for other marine societies, we can carry out marine testing in one of our in-house, state-of-the-art marine facilities.
