For” Excellence At Sea”, Power Your Watercraft With A Marine-Grade Alternator.
- The choice to upgrade your vessel’s charging system will often include considerations regarding your engine’s alternator.
- A marine alternator is designed to withstand the rigors of the maritime environment- a special kind of alternator that's designed to handle damp and humid conditions.
- They come with plated fans, pulleys, and hardware for corrosion resistance and even flame arrestor screens to meet Marine certification.
- These devices can be installed directly on the main engine or on a generator set.
How To Choose?
- Alternators are extremely useful when a vessel carries equipment with high power demands such as thrusters, windlass, and air conditioning.
- Determine electrical needs over 24 hours, both for charging and direct use, to calculate power requirements. Some supplementary power alternators are compatible only with specific engine makes and models. Be sure to supply this information to the manufacturer.
What To Look For In Marine-Grade Alternator?
It should meet U.S. Coast Guard Title 33 safety protection standards. If the alternator is being installed on a gasoline engine, the alternator should also comply with international SAE standards for ignition protection.
- Heavy-duty construction:
As Marine alternators operate at sustained high output for much of their lives they require high-temperature grease, large cooling passages, large or multiple fans, heavy-duty bearings, and high-amperage diodes
Why Do Standard Automotive-Type Alternators Not Used In Marine Charging Systems?
- Standard automotive-type alternators rarely offer the construction required to meet the demands of large marine charging systems.
- On most stock marine engines, the factory-supplied alternators are inadequate for charging a large heavily depleted house bank of batteries. In almost all cases they are simply not designed for extended heavy-duty operation charging large banks of batteries.
- Dual alternators are an increasingly popular alternative on many engines. If excited by a single multi-stage regulator, both alternators can work together to handle large single battery banks.
- A step-down/step-up alternator may be used along with a standard model to serve as a supplementary power source.
Steyr Motors, Balmer, WEG Automation, ENAG, Mastervolts, Dynawatt, Volvo Penta are some of the trusted International brands that offer alternators from small boats to cruise ships and for Trawlers to Fishing fleets.
